Question: What are the treatments for Hypoglycemia ?
Answer: Signs and symptoms of hypoglycemia vary from person to person. People with diabetes should get to know their signs and symptoms and describe them to their friends and family so they can help if needed. School staff should be told how to recognize a child's signs and symptoms of hypoglycemia and how to treat it.
People who experience hypoglycemia several times in a week should call their health care provider. They may need a change in their treatment plan: less medication or a different medication, a new schedule for insulin or medication, a different meal plan, or a new physical activity plan.
Prompt Treatment for Hypoglycemia
When people think their blood glucose is too low, they should check the blood glucose level of a blood sample using a meter. If the level is below 70 mg/dL, one of these quick-fix foods should be consumed right away to raise blood glucose:
- 3 or 4 glucose tablets - 1 serving of glucose gelthe amount equal to 15 grams of carbohydrate - 1/2 cup, or 4 ounces, of any fruit juice - 1/2 cup, or 4 ounces, of a regularnot dietsoft drink - 1 cup, or 8 ounces, of milk - 5 or 6 pieces of hard candy - 1 tablespoon of sugar or honey
Recommended amounts may be less for small children. The child's doctor can advise about the right amount to give a child.
The next step is to recheck blood glucose in 15 minutes to make sure it is 70 mg/dL or above. If it's still too low, another serving of a quick-fix food should be eaten. These steps should be repeated until the blood glucose level is 70 mg/dL or above. If the next meal is an hour or more away, a snack should be eaten once the quick-fix foods have raised the blood glucose level to 70 mg/dL or above.
For People Who Take Acarbose (Precose) or Miglitol (Glyset)
People who take either of these diabetes medications should know that only pure glucose, also called dextroseavailable in tablet or gel formwill raise their blood glucose level during a low blood glucose episode. Other quick-fix foods and drinks won't raise the level quickly enough because acarbose and miglitol slow the digestion of other forms of carbohydrate.
Help from Others for Severe Hypoglycemia
Severe hypoglycemiavery low blood glucosecan cause a person to pass out and can even be life threatening. Severe hypoglycemia is more likely to occur in people with type 1 diabetes. People should ask a health care provider what to do about severe hypoglycemia. Another person can help someone who has passed out by giving an injection of glucagon. Glucagon will rapidly bring the blood glucose level back to normal and help the person regain consciousness. A health care provider can prescribe a glucagon emergency kit. Family, friends, or coworkersthe people who will be around the person at risk of hypoglycemiacan learn how to give a glucagon injection and when to call 911 or get medical help.
Physical Activity and Blood Glucose Levels
Physical activity has many benefits for people with diabetes, including lowering blood glucose levels. However, physical activity can make levels too low and can cause hypoglycemia up to 24 hours afterward. A health care provider can advise about checking the blood glucose level before exercise. For those who take insulin or one of the oral medications that increase insulin production, the health care provider may suggest having a snack if the glucose level is below 100 mg/dL or adjusting medication doses before physical activity to help avoid hypoglycemia. A snack can prevent hypoglycemia. The health care provider may suggest extra blood glucose checks, especially after strenuous exercise.
Hypoglycemia When Driving
Hypoglycemia is particularly dangerous if it happens to someone who is driving. People with hypoglycemia may have trouble concentrating or seeing clearly behind the wheel and may not be able to react quickly to road hazards or to the actions of other drivers. To prevent problems, people at risk for hypoglycemia should check their blood glucose level before driving. During longer trips, they should check their blood glucose level frequently and eat snacks as needed to keep the level at 70 mg/dL or above. If necessary, they should stop for treatment and then make sure their blood glucose level is 70 mg/dL or above before starting to drive again.
Hypoglycemia Unawareness
Some people with diabetes do not have early warning signs of low blood glucose, a condition called hypoglycemia unawareness. This condition occurs most often in people with type 1 diabetes, but it can also occur in people with type 2 diabetes. People with hypoglycemia unawareness may need to check their blood glucose level more often so they know when hypoglycemia is about to occur. They also may need a change in their medications, meal plan, or physical activity routine.
Hypoglycemia unawareness develops when frequent episodes of hypoglycemia lead to changes in how the body reacts to low blood glucose levels. The body stops releasing the hormone epinephrine and other stress hormones when blood glucose drops too low. The loss of the body's ability to release stress hormones after repeated episodes of hypoglycemia is called hypoglycemia-associated autonomic failure, or HAAF.
Epinephrine causes early warning symptoms of hypoglycemia such as shakiness, sweating, anxiety, and hunger. Without the release of epinephrine and the symptoms it causes, a person may not realize that hypoglycemia is occurring and may not take action to treat it. A vicious cycle can occur in which frequent hypoglycemia leads to hypoglycemia unawareness and HAAF, which in turn leads to even more severe and dangerous hypoglycemia. Studies have shown that preventing hypoglycemia for a period as short as several weeks can sometimes break this cycle and restore awareness of symptoms. Health care providers may therefore advise people who have had severe hypoglycemia to aim for higher-than-usual blood glucose targets for short-term periods.
Being Prepared for Hypoglycemia
People who use insulin or take an oral diabetes medication that can cause low blood glucose should always be prepared to prevent and treat low blood glucose by
- learning what can trigger low blood glucose levels - having their blood glucose meter available to test glucose levels; frequent testing may be critical for those with hypoglycemia unawareness, particularly before driving a car or engaging in any hazardous activity - always having several servings of quick-fix foods or drinks handy - wearing a medical identification bracelet or necklace - planning what to do if they develop severe hypoglycemia - telling their family, friends, and coworkers about the symptoms of hypoglycemia and how they can help if needed
Normal and Target Blood Glucose Ranges Normal Blood Glucose Levels in People Who Do Not Have Diabetes Upon wakingfasting 70 to 99 mg/dL After meals 70 to 140 mg/dL Target Blood Glucose Levels in People Who Have Diabetes Before meals 70 to 130 mg/dL 1 to 2 hours after the start of a meal below 180 mg/dL
For people with diabetes, a blood glucose level below 70 mg/dL is considered hypoglycemia.
