Title: Electronic device and method for notification of biometric information by electronic device

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2019-0031241, filed on Mar. 19, 2019, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety. 
     BACKGROUND 
     Field 
     The disclosure relates to an electronic device and a method for providing a notification associated with biometric information by the electronic device. 
     Description of Related Art 
     Recently, various electronic devices are being developed to measure biometric information of users and to provide various health-related information on the basis of the measured biometric information. For example, measured biometric information may be used to determine whether there is an abnormality in a user&#39;s health condition. 
     In an electronic device, various applications (e.g., referred to as “apps”) may be installed and executed. The applications may monitor a user&#39;s health condition by periodically measuring the user&#39;s biometric information. 
     An electronic device may measure biometric information of a user and may provide state information related to various diseases. For example, the electronic device may determine whether a blood sugar level of the user corresponds to hypoglycemia. Hypoglycemia may occur when a patient has too much insulin, fails to eat a meal, or suddenly increases an exercise amount, and it is a side effect that occurs during diabetes treatment. When blood sugar drops, a patient has hunger, lethargy, trembles, shakes, sweats, dizziness, headaches, etc., and may lose consciousness in a severe case. 
     Moreover, a patient who already has hypoglycemia is more likely to relapse, and frequent occurrence of hypoglycemia may lead to decreased intelligence, a secondary accident, or the like, and may lead to loss of life in a severe case, so it is very important to predict an occurrence of hypoglycemia by monitoring pre-symptoms. 
     SUMMARY 
     Embodiments of the disclosure provide an electronic device and a method for determining health information by the electronic device that may enable an occurrence of hypoglycemia to be predicted and may allow various notifications based on blood sugar levels to be provided, based on various context information of a user. 
     An electronic device according to various example embodiments of the disclosure may include: a sensor module; an output device comprising output circuitry; a processor operatively connected to the sensor module and the output device; and a memory operatively connected to the processor, wherein the memory is configured to store instructions that, when executed, cause the processor to control the electronic device to: identify a blood sugar level measured at every first period via the sensor module; output a hypoglycemia prediction notification based on an amount of change in decrease of the blood sugar level exceeding a designated first value; and measure a blood sugar level at every second period, the second period being shorter than the first period via the sensor module based on a blood sugar level identified after the notification is output being equal to or less than a second value. 
     A method for biometric information notification by an electronic device according to various example embodiments of the disclosure may include: identifying a blood sugar level measured at every first period; outputting a hypoglycemia prediction notification via an output device based on an amount of change in decrease of the blood sugar level exceeding a designated first value; and measuring a blood sugar level at every second period, the second period being shorter than the first period, based on a blood sugar level identified after the notification is output being equal to or less than a designated value. 
     According to various example embodiments of the disclosure, an electronic device and a method for biometric information notification by the electronic device may enable occurrence of hypoglycemia to be predicted, and a blood sugar measurement period and a notification output to be configured based on movement information and a biometric signal to enable the user to predict occurrence of hypoglycemia in various situations and take action against hypoglycemia.

     According to various embodiments of the disclosure, the electronic device  200  may measure a biometric signal via the sensor module  176 , or may receive, via the communication module  190 , biometric information measured by an external electronic device (e.g., the electronic device  102 ). 
     According to various embodiments of the disclosure, the processor  120  may include various processing circuitry and control overall operations of the electronic device  200 . For example, the processor  120  may determine the possibility of hypoglycemia based on various information related to a user, and may provide a notification related to hypoglycemia to the user. 
     According to various embodiments of the disclosure, the processor  120  may determine a movement state of the user. For example, the processor  120  may determine whether the user is exercising, inactive (sedentary), sleeping, eating, or drinking. 
     According to various embodiments of the disclosure, the processor  120  may check a health record of the user. For example, the health record may be input by the user or may be transmitted from an external electronic device (e.g., a medical institution). The health record may include the user&#39;s gender, age, height, weight, disease information (e.g., the presence or absence of diabetes, or a frequency of occurrence of hypoglycemia), medication information, race, family history, the presence or absence of an allergy, or the like, and may further include various information related to the health of the user. 
     According to various embodiments of the disclosure, the processor  120  may check environment information of the user. The environment information may include information related to a surrounding environment of the electronic device  200 , and may include GPS information, temperature information, or humidity information. 
     According to various embodiments of the disclosure, the display device  160  may output image or text data. For example, the processor  120  may predict biometric information of the user, and may control the display  160  to output a notification relating to the prediction in the form of image or text data. 
     According to various embodiments of the disclosure, the sensor module  176  may include, for example, and without limitation, at least one of a gyro sensor, an acceleration sensor, a grip sensor, a proximity sensor, a temperature sensor, or a biometric sensor, and may include various sensors that sense the user&#39;s movement or biometric information. 
     According to various embodiments of the disclosure, the biometric sensor may sense a biometric signal of the user when the biometric sensor non-invasively contacts (or approaches) a part of the user&#39;s body. The processor  120  may determine, based on the biometric signal, at least one of electrocardiogram (ECG), photoplethysmography (PPG), impedance plethysmography, body temperature, blood sugar, electroencephalogram (EEG), blood pressure, heart rate (HR), or sweat components. 
     According to various embodiments of the disclosure, the processor  120  may determine the user&#39;s movement state based on a signal sensed via the sensor module  176 . For example, the processor  120  may determine a movement state in various situations, such as whether the user is exercising, inactive, sleeping, or eating, based on a signal of movement measured by the sensor module  176 . 
     According to various embodiments of the disclosure, the processor  120  may determine an appropriate blood sugar level, a direction of change in blood sugar, or a blood sugar change rate according to the user&#39;s movement state. For example, the processor  120  may predict occurrence of hypoglycemia, based on a blood sugar level that is lower than the appropriate blood sugar level, a direction of change in blood sugar, which indicates a decrease, or a blood sugar change rate that is equal to or greater than a designated value, in a state where the user is exercising, inactivity, sleep, or eating. 
     According to various embodiments of the disclosure, even when the user usually shows a normal blood sugar level, glucose concentrations in the blood may be lowered due to sudden exercise, and temporary hypoglycemia may occur. For example, the processor  120  may determine whether the user has experienced hypoglycemia, based on the user&#39;s health information, and may predict whether hypoglycemia is likely to be continued after the user finishes exercise. 
     According to various embodiments of the disclosure, if the possibility of occurrence of hypoglycemia is predicted, the processor  120  may output various types of data (e.g., image data or vibration data) to induce the user to stop exercising and measure blood sugar. 
     According to various embodiments of the disclosure, the user may develop nighttime hypoglycemia with an extremely low blood sugar level while sleeping. For example, the processor  120  may determine that the user is sleeping, based on a movement state, and may determine whether night hypoglycemia occurs. 
     According to various embodiments of the disclosure, if occurrence of night hypoglycemia is expected based on health information of the user, the processor  120  may output an alarm (e.g., vibration data) to allow the user to measure blood sugar at a specific time (e.g., 2 to 3 am), or may automatically measure blood sugar. 
     According to various embodiments of the disclosure, the processor  120  may configure a measurement period according to a hypoglycemia occurrence state, to measure a blood sugar level. For example, the hypoglycemia occurrence state may include a non-occurrence state, an initial hypoglycemia state, a hypoglycemia predicted state, a hypoglycemia occurrence confirmed state, or a recovering state. 
     According to various embodiments of the disclosure, the non-occurrence state may indicate a user state in which hypoglycemia has not previously occurred. For example, the processor  120  may perform control to measure blood sugar every first period (e.g., one week). 
     According to various embodiments of the disclosure, the initial hypoglycemia state may indicate a user state in which a blood sugar level is lower than a usual blood sugar level. For example, the processor  120  may perform control to measure blood sugar at every second period (e.g., five minutes) which is shorter than the first period. 
     According to various embodiments of the disclosure, the hypoglycemia predicted state may indicate a state in which occurrence of hypoglycemia is predicted based on previously measured blood sugar information when the rate of decrease in blood sugar level is equal to or greater than a designated value. For example, the processor  120  may output a notification informing prediction of occurrence of hypoglycemia, and may perform control to measure blood sugar at every third period (e.g., one minute) which is shorter than the second period, thereby rapidly measuring a change in blood sugar of the user. 
     According to various embodiments of the disclosure, the hypoglycemia occurrence confirmation state may be a state in which the user&#39;s blood sugar level is measured to be lower than a value corresponding to hypoglycemia, so that it is determined that hypoglycemia has occurred in the user. For example, the processor  120  may perform control to measure blood sugar at every fourth period (e.g., 30 seconds) which is shorter than the third period. 
     According to various embodiments of the disclosure, if it is determined that the user is in the hypoglycemia predicted state or the hypoglycemia occurrence confirmed state, the processor  120  may output a notification encouraging the user to intake sugar (e.g., cola, orange juice, milk, sugar cubes, etc.) which enables fastest absorption of blood sugar. For example, if a user input for the notification is not received, the processor  120  may make an emergency call or may transmit information related to the occurrence of hypoglycemia of the user to a designated contact or a medical institution. 
     According to various embodiments of the disclosure, the recovering state may be a state in which the user previously had hypoglycemia, but the user&#39;s blood sugar level has been measured to be normal for a predetermined period of time. For example, based on checking of a previous hypoglycemia occurrence history for the user, the processor  120  may perform control to measure blood sugar at every fifth period (e.g., 24 hours) which is longer than the second period that is shorter than the first period. 
     According to various embodiments of the disclosure, the electronic device  200  may determine a hypoglycemia occurrence state based on various determination conditions, may configure a blood sugar measurement period according to the hypoglycemia occurrence state, and may output a hypoglycemia prediction notification. 
     Table 1 relates to an output configuration of a hypoglycemia prediction notification and a blood sugar measurement period preconfigured for the hypoglycemia occurrence state according to various embodiments of the disclosure.

For example, when the sensor module  176  embedded in the display device  160  includes a biometric sensor (e.g., a PPG sensor), the biometric sensor may acquire biometric information (e.g., an amount of blood sugar) associated with a touch input via a partial area of the display of the display device  160 , which is exposed to the outside. 
     According to various embodiments of the disclosure, the at least one sensor may be disposed between pixels of a pixel layer of the display, or above or below the pixel layer. For example, the electronic device  101  may control the display device  160  to display an interface  410  configured to measure biometric information (e.g., an amount of blood sugar), wherein the interface  410  may include text for inducing contact of a part of the body, which is for measurement of biometric information, and an object indicating a part where the part of the body is in contact. 
       FIG. 4B  is a diagram illustrating a rear view of an example electronic device according to various embodiments of the disclosure. 
     Referring to  FIG. 4B , the electronic device  101 , in the form of a smartphone, may sense proximity (or touch) of a part of the body of a user  400  via the sensor module  176 . For example, the sensor module  176  may include a light emission unit and a light reception unit. 
     According to various embodiments of the disclosure, if proximity of the user  400  is sensed via the proximity sensor of the sensor module  176 , the electronic device  101  may control the light emission unit to output (or emit), to the user, a signal (e.g., light) for acquisition of information for a blood sugar level in blood. For example, transmitted light or light reflected by the output light may be received in the light reception unit. 
     According to various embodiments of the disclosure, the electronic device  200  may measure the amount of light received in the light reception unit to measure a biometric signal of the user.

     According to various embodiments of the disclosure, the electronic device  200  may output a notification informing the user to stop exercising or encouraging the user to ingest food that can immediately raise blood sugar, based on measured biometric information and whether the user has hypoglycemia. For example, if no user input is identified within a designated time after the output of the notification, the electronic device  200  may control an emergency message to be transmitted to a designated contact. 
       FIG. 5  is an flowchart illustrating an example operation of providing a notification associated with biometric information by an electronic device according to various embodiments of the disclosure. 
     Referring to  FIG. 5 , in operation  510 , an electronic device (e.g., the electronic device  101  of  FIG. 1 ,  FIG. 4A , or  FIG. 4B  or the electronic device  200  of  FIG. 2  and  FIG. 3 ) may check a blood sugar level of a user, which may be measured at every first period. 
     In operation  520 , if the amount of change in decrease of the blood sugar level exceeds a designated first value, the electronic device may output a hypoglycemia prediction notification. 
     In operation  530 , if the blood sugar level checked after the output of the notification is equal to or lower than a designated second value, the electronic device may measure a blood sugar level at every second period, the second period being less than the first period. 
     A method for providing a biometric information notification by the electronic device according to various example embodiments of the disclosure may further include: outputting a first notification informing the occurrence of hypoglycemia based on occurrence of hypoglycemia being determined based on the blood sugar level measured at every second period; and outputting the first notification at every second period. 
     The method for providing a biometric information notification by the electronic device according to various example embodiments of the disclosure may further include outputting the first notification at every third period corresponding to the amount of change in decrease of the blood sugar level. 
     The method for providing a biometric information notification by the electronic device according to various example embodiments of the disclosure may further include making an emergency call if no user input is received in response to the first notification within a predesignated time. 
     A data type included in the hypoglycemia prediction notification according to various example embodiments of the disclosure may include at least one of vibration data output via the haptic module  179 , voice data output via the sound output device  155 , text output via the display device  160 , or image data output via the display device  160 . 
     The method for providing a biometric information notification by the electronic device according to various example embodiments of the disclosure may further include: determining that the user is in a sleeping state; and in the sleeping state in which the user is sleeping, outputting the voice data or vibration data, which induces the user to wake up based on a rate of decrease in the blood sugar level measured at every first period exceeding a designated value. 
     The method for providing a biometric information notification by the electronic device according to various example embodiments of the disclosure may further include, outputting the hypoglycemia prediction notification including a content that induces glucose intake based on it being determined that the user is in a wake-up state. 
     The method for providing a biometric information notification by the electronic device according to various example embodiments of the disclosure may further include, outputting the hypoglycemia prediction notification at every configured period based on no predesignated user input being received within a designated time after the output of the hypoglycemia prediction notification. 
     The method for providing a biometric information notification by the electronic device according to various example embodiments of the disclosure may further include: measuring a biometric signal for the user; and determining whether hypoglycemia has occurred in the user based on a pattern of the measured biometric signal. 
       FIG. 6  is a flowchart illustrating an example operation of predicting hypoglycemia based on biometric information and providing a notification by the electronic device according to various embodiments of the disclosure. 
     Referring to  FIG. 6 , in operation  610 , the electronic device  200  may monitor biometric information of a user. The biometric information may include information indicating the user&#39;s blood sugar level, heart rate, blood pressure, stress (heart rate variability), or sweat amount. 
     In operation  620 , the electronic device  200  may measure the amount of change in blood sugar of the user. For example, the electronic device  200  may measure the amount of change in blood sugar at every designated period (e.g., at every 5 minutes). 
     In operation  621 , the electronic device  200  may determine whether the rate of blood sugar decrease exceeds a designated value (e.g., 1 mg/dl/min). 
     In operation  621 , if the amount of change in blood sugar is equal to or less than the designated value, the electronic device  200  may perform operation  620  to measure the amount of change in blood sugar. 
     In operation  621 , if the amount of blood sugar decreases at a rate exceeding the designated value, the electronic device  200  may determine, in operation  623 , whether the blood sugar level is lower than a first threshold value. For example, the first threshold value may be configured to determine whether the electronic device  200  outputs a hypoglycemia prediction notification when hypoglycemia has not occurred in the user but the possibility of occurrence of hypoglycemia is high. 
     As a result of performing operation  623 , if the blood sugar level is equal to or higher than the first threshold value, the electronic device  200  may perform operation  620  to measure the amount of change in blood sugar. 
     As the result of performing operation  623 , if the blood sugar level is lower than the first threshold value, the electronic device  200  may determine movement information of the user in operation  630 . For example, the movement information may include information indicating whether the user is exercising, sleeping, eating, or drinking. 
     In operation  640 , the electronic device  200  may output a hypoglycemia prediction notification based on the movement information of the user. 
     According to various embodiments of the disclosure, if the blood sugar level of the user is lower than the first threshold value and the user is exercising, the electronic device  200  may determine that the user is temporarily in a hypoglycemia state due to the exercise. For example, the electronic device  200  may output, as the hypoglycemia prediction notification, information for encouraging the user to stop exercising and take a rest. 
     According to various embodiments of the disclosure, the electronic device  200  may include information of a proper exercise time in the hypoglycemia prediction notification. For example, because the blood sugar level is measured at a highest value when 1 hour has passed after a meal, the electronic device  200  may output the hypoglycemia prediction notification including information for recommending to exercise when the blood sugar level is the highest value after the meal. 
     According to various embodiments of the disclosure, the electronic device  200  may determine that the user&#39;s blood sugar level is lower than the first threshold value, and the user is in an inactive state. For example, the electronic device  200  may output, as the hypoglycemia prediction notification, a notification for recommending to increase blood sugar by taking glucose. 
     In operation  650 , the electronic device  200  may determine whether the user&#39;s blood sugar level is measured to be less than a second threshold value. For example, the second threshold value is a value less than the first threshold value, and may be configured to a blood sugar level corresponding to occurrence of hypoglycemia. 
     As the result of performing operation  650 , if the user&#39;s blood sugar level is lower than the second threshold value, the electronic device  200  may determine hypoglycemia has occurred in the user. 
     As the result of performing operation  650 , if the user&#39;s blood sugar level is equal to or higher than the second threshold value, the electronic device  200  may perform operation  620  to measure the amount of change in blood sugar. 
     As the result of performing operation  650 , if it is determined that the blood sugar level is less than the second threshold value within a designated time, the electronic device  200  may determine, in operation  660 , that hypoglycemia has occurred in the user. 
     In operation  670 , the electronic device  200  may transmit an emergency message (or an emergency notification and contact). For example, the emergency notification and contact may allow transmission of information informing occurrence of hypoglycemia of the user to a predesignated institution (e.g., a fire department or a hospital) or a predesignated contact. 
       FIG. 7  is a diagram illustrating an example biometric information prediction notification output by the electronic device according to various embodiments of the disclosure. 
     Referring to  FIG. 7 , the electronic device  200  may include at least one among the display device  160 , the sound output device  155 , and the haptic module  179 . 
     According to various embodiments of the disclosure, the electronic device  200  may measure an amount of user&#39;s blood sugar, and may output a hypoglycemia prediction notification based on the measured amount of blood sugar and movement information of the user. For example, the electronic device  200  may determine that the user is exercising, and a blood sugar level is lower than a threshold value (90 mg/dl) for outputting of the hypoglycemia prediction notification. 
     According to various embodiments of the disclosure, the electronic device  200  may determine that, even if the amount of blood sugar, which is measured for the user, does not indicate occurrence of hypoglycemia, because the user is exercising, the amount of blood sugar corresponds to a range (e.g., 70-80 mg/dl) lower than usual. For example, the electronic device  200  may control the output device  210  (e.g., the display device  160 ) to display, as the hypoglycemia prediction notification, information  710  of the current amount of blood sugar and a content  720  (e.g., “Stop exercising and take a rest for 10 minutes”.) informing the user to stop exercising. 
     According to various embodiments of the disclosure, the electronic device  200  may output the hypoglycemia prediction notification in various forms according to the movement information of the user. For example, when it is determined that the user is exercising and is thus unable to check the electronic device  200 , the electronic device  200  may control the output device (e.g., the haptic module  179 , the sound output device  155 , or the output device  210  of  FIG. 2 ) of the electronic device  200  to output non-visual data (e.g., sound data  701  or vibration data  702 ). 
       FIG. 8  is a flowchart illustrating an example operation of outputting a hypoglycemia prediction notification by the electronic device according to various embodiments of the disclosure. 
     Referring to  FIG. 8 , in operation  810 , the electronic device  200  may predict a probability of occurrence of hypoglycemia for a user. For example, the electronic device  200  may monitor an amount of blood sugar, and if it is determined that the amount of a user&#39;s blood sugar decreases at a rate exceeding a designated value and a blood sugar level is higher than a value corresponding to hypoglycemia, the electronic device  200  may determine that hypoglycemia is likely to occur. 
     In operation  820 , the electronic device  200  may measure a heart rate of the user and may determine whether the measured user&#39;s heart rate is equal to or greater than a designated value. 
     As the result of performing operation  820 , if the user&#39;s heart rate is lower than the designated value, the electronic device  200  may predict the possibility of occurrence of hypoglycemia in operation  810 . 
     As the result of performing operation  820 , if the user&#39;s heart rate is equal to or greater than the designated value, the electronic device  200  may output a hypoglycemia prediction notification in operation  830 . 
     According to various embodiments of the disclosure, the electronic device  200  may determine that the change in the heart rate is caused by the response of sympathetic nerves when the heart rate is equal to or greater than the designated value. The electronic device  200  may determine not only the change in the heart rate but also a change the amount of sweat, tremor, or breath. 
     In operation  840 , the electronic device  200  may determine occurrence of hypoglycemia. For example, after the hypoglycemia prediction notification is output, if the amount of the user&#39;s blood sugar is measured to correspond to a value corresponding to hypoglycemia, the electronic device  200  may determine that hypoglycemia has occurred in the user. 
     In operation  850 , the electronic device  200  may transmit an emergency message to a designated contact if an occurrence of hypoglycemia is determined in operation  840 . For example, the designated contact may be the user&#39;s contact number preconfigured by the user, or may include a contact (e.g.,  911 ) of a rescue agency to transmit an immediate rescue request. 
     According to various embodiments of the disclosure, the electronic device  200  may output the hypoglycemia prediction notification, and may monitor biometric information of the user to determine whether hypoglycemia occurs. Based on the determination, the electronic device  200  may not only output the notification but also perform control to make an emergency call to contacts (e.g., a rescue agency or a hospital) allowing urgent help for the user. 
       FIG. 9  is a graph illustrating examples of change in a biometric signal of a user when hypoglycemia occurs, according to various embodiments of the disclosure. 
     Referring to  FIG. 9 , the electronic device  200  may check changes in electroencephalogram, blood pressure, and heart rate according to a hypoglycemia occurrence state of a user. 
     According to various embodiments of the disclosure, if a user is in an inactive state  910 , the electroencephalogram and blood pressure may be measured at a constant value without a change in the amplitude. 
     According to various embodiments of the disclosure, the electronic device  200  may check the amount of the user&#39;s blood sugar, and if the amount of the user&#39;s blood sugar has a value lower than a normal range but higher than a value for determination of hypoglycemia, the electronic device  200  may determine that the user is in an early hypoglycemia state  920 . For example, in the early hypoglycemia state  920 , the amplitude is increased compared to a graph of change in electroencephalogram for the inactive state  910 , and a reduced amplitude may (e.g., 80 mmHg) be measured compared to a graph of change in blood pressure. 
     According to various embodiments of the disclosure, in the electronic device  200 , a pattern (isoelectric pattern) with almost no change in electroencephalogram (e.g., 200 μV/sec) appears in a hypoglycemia state  930  due to the amount of the user&#39;s blood sugar, which is lower than a designated value, and the blood pressure and heart rate in the hypoglycemia state  930  may be measured to show increased amplitudes compared to an inactive (normal) state  910  and the early hypoglycemia state  920 . 
     According to various embodiments of the disclosure, if hypoglycemia occurs in the user and then the blood sugar level is measured to be normal, the electronic device  200  may determine that the user is in a recovering state  940 . In the recovering state  940 , the amplitude of the electroencephalogram may be measured to be higher than that in the normal state  910 , but may be measured to be lower than that in the early hypoglycemia state  920 . The blood pressure in the recovering state  940  is similar to the pattern in the hypoglycemia state  930 , but the amplitude may be measured to be low. 
     According to various embodiments of the disclosure, the electronic device  200  may determine a hypoglycemia occurrence state by means of a biometric signal measured for a user, based on graphs of changes in the biometric signal according to various hypoglycemia occurrence states. 
       FIG. 10  is a flowchart illustrating an example operation of determining whether to output a hypoglycemia prediction notification, by the electronic device according to various embodiments of the disclosure. 
     Referring to  FIG. 10 , in operation  1010 , the electronic device  200  may output a hypoglycemia prediction notification. The hypoglycemia prediction notification may be output if a blood sugar level of a user decreases at a rate equal to or higher than a designated value and has a value corresponding to a designated range. 
     In operation  1020 , the electronic device  200  may determine whether a user input for the notification is received. For example, the electronic device  200  may configure, in advance, a type of the user input according to a situation of the user, which corresponds to movement information of the user. 
     According to various embodiments of the disclosure, the electronic device  200  may determine that the user is sleeping. For example, the electronic device  200  may determine whether the user is sleeping, by checking movement pattern information of the user, which is acquired by a sensor (e.g., an acceleration sensor) of the electronic device  200 . 
     According to various embodiments of the disclosure, the electronic device  200  may determine that the user is sleeping, and may output the notification in various data forms in order to wake up the user. For example, the notification may include sound data or vibration data via a notification application. If it is determined that the user woke up within a designated time after the output of the notification, the electronic device  200  may determine that a designated user input has been received. 
     According to various embodiments of the disclosure, the electronic device  200  may determine that the user is in an inactive state. For example, the electronic device  200  may output a notification informing that, even if the user is in the inactive state, there may be a possibility of occurrence of hypoglycemia. For example, the notification may include a recommendation for immediate glucose intake. 
     According to various embodiments of the disclosure, the user may input a response to the notification, to the electronic device  200 . For example, the user input may include a specific action (e.g., sitting) or gesture input, or voice data (e.g., “yes” or “alright”), and various forms of data which can be input via various input devices may be additionally possible. 
     As the result of performing operation  1020 , if the user input for the notification is received, the electronic device  200  may stop outputting of the hypoglycemia prediction notification, in operation  1030 . For example, the electronic device  200  may determine that the user has checked the notification and taken a self-measurement to increase blood sugar, and may measure an amount of blood sugar in the background. 
     As the result of performing operation  1020 , if no user input predesignated for the notification is received, the electronic device  200  may determine whether hypoglycemia has occurred, in operation  1040 . For example, the electronic device  200  may determine whether the user&#39;s blood sugar level has a value corresponding to hypoglycemia. 
     According to various embodiments of the disclosure, the electronic device  200  may output a hypoglycemia prediction notification, and may stop outputting the hypoglycemia prediction notification or may determine whether hypoglycemia has occurred in a user, according to whether a user input has been received in response to the notification. 
       FIG. 11  is a diagram illustrating an example of a hypoglycemia prediction notification configuration in the electronic device according to various embodiments of the disclosure. 
     Referring to  FIG. 11 , the electronic device  200  may output a hypoglycemia occurrence notification via the display device  160 . 
     According to various embodiments of the disclosure, the electronic device  200  may measure an amount of blood sugar of a user, and may determine whether the measured amount of blood sugar has a value corresponding to hypoglycemia. For example, if the amount of blood sugar is measured to be a value less than 70 mg/dl, it may be determined that hypoglycemia has occurred in the user. 
     According to various embodiments of the disclosure, the electronic device  200  may output various notifications informing occurrence of hypoglycemia in the user. For example, the notification may include information (e.g., “extremely low”)  1120  alerting that the user&#39;s blood sugar level (e.g., 65 mg/dl)  1110  or the amount of blood sugar is extremely low. 
     According to various embodiments of the disclosure, the electronic device  200  may determine whether a user input is made within a designated time after the hypoglycemia occurrence notification is output. For example, the user input may include various types of data indicating whether the user has checked the notification. 
       FIG. 12  is a diagram illustrating an example of a hypoglycemia occurrence notification configuration in the electronic device according to various embodiments of the disclosure. 
     Referring to  FIG. 12 , if it is determined that hypoglycemia has occurred in a user, the electronic device  200  may transmit a call to an emergency contact. 
     According to various embodiments of the disclosure, the electronic device  200  may determine that hypoglycemia has occurred in the user when a blood sugar level  1210  of the user is measured to be lower than a value (e.g., 70 mg/dl) corresponding to hypoglycemia. For example, the electronic device  200  may display, via the display device  160 , a current blood sugar level  1210 , an emergency call origination notification  1220 , and a button  1230  that allows termination of a call. 
     According to various embodiments of the disclosure, the electronic device  200  may transmit an emergency call (e.g., 911) or may transmit a message including information related to occurrence of hypoglycemia in the user to a designated contact, according to whether movement information of a user or a user input for a previous hypoglycemia prediction notification has been received. 
     For example, if movement information of the user cannot be checked, there is no movement change, or no record for reception of a user input for the hypoglycemia prediction notification within a designated time, the electronic device  200  may determine that the user is unable to perform self-measurement for hypoglycemia and may transmit an emergency call. 
     According to various embodiments of the disclosure, if the user has recovered from hypoglycemia or has failed to check the emergency call origination notification  1220 , the user may select the button  1230  to stop the emergency call. For example, when the button  1230  is selected, the electronic device  200  may stop transmitting the emergency call, and periodically measure the user&#39;s blood sugar to determine whether hypoglycemia occurs in the user. 
       FIG. 13  is a diagram illustrating an example data configuration for designing a hypoglycemia prediction notification model by the electronic device according to various embodiments of the disclosure. 
     Referring to  FIG. 13 , the electronic device  200  may check data  1300  related to a user. For example, the data  1300  may include the user&#39;s movement state, biometric signal, health record, or environment information. 
     According to various embodiments of the disclosure, the movement state may include information indicating a current activity state of the user, which indicates whether the user is exercising, sleeping, eating, drinking, or the like. The biometric signal may include biometric information of the user, which is measured via a sensor module  176  of the electronic device  200 , and may include information indicating blood sugar, heart rate, heart rate variability (stress), amount of sweat, degree of tremor, or the like. The health record may include information related to the user&#39;s health, and may include information, such as gender, age, height/weight, the presence or absence of diabetes, medication information, or a frequency of hypoglycemia. The environment information may include information of the user&#39;s surrounding environment and may include GPS information, temperature information, or humidity information. 
     According to various embodiments of the disclosure, in operation  1310 , the electronic device  200  may extract various features related to hypoglycemia based on the data  1300 . For example, the various features related to hypoglycemia may include a blood sugar level for occurrence of hypoglycemia, a rate value of decrease in blood sugar, hypoglycemia occurrence context information, or the like. 
     According to various embodiments of the disclosure, the electronic device  200  may determine movement information of the user and a blood sugar level measured for the user, and if the movement information and blood sugar level correspond to the extracted feature, the electronic device may determine to output the hypoglycemia prediction notification. 
     According to various embodiments of the disclosure, in operation  1320 , the electronic device  200  may design a hypoglycemia prediction notification model. For example, the hypoglycemia prediction notification model may include various configurations related to output of the hypoglycemia prediction notification, such as a notification output period, an output time, a type of data included in the notification, a blood sugar measurement period, an output method, etc., for each of the extracted various features. 
     According to various embodiments of the disclosure, the electronic device  200  may extract various features for determining occurrence of hypoglycemia, and may perform modeling for extracting a hypoglycemia prediction notification therefor, based on the data  1300  for a user.
