What is diabetes?   * It is a high metabolic disease that causes high blood sugar (“Diabetes Basics”).   * Sugar also known as glucose is a body’s necessary fuel to sustain.   * Insulin is a hormone that ensures the transfer of sugar from the blood and delivers it into the muscle, liver and fat tissues where sugar is used as energy source or stored for the body to use later.   * If a person does not have enough insulin, sugar accumulates in his blood stream, causing diabetes. Symptoms of Diabetes The onset of symptoms may appear suddenly or gradually depending on each case.   * Unexplained weight loss;   * Excessive thirst or hunger;   * Fatigue;   * Frequent urination;   * Blurred vision;   * Nausea and/or vomiting (“Diabetes Basics”). Once symptoms are notices, immediate medical care is needed. Hypo and Hyperglycemia in the Context of Diabetes   * Hypoglycemia is a condition where the level of sugar is lower than normal. People with diabetes who take insulin more than they need may end up with hypoglycemia. Symptoms of low sugar level if a person has diabetes are weakness, headaches, lightheadedness, and dizziness.   * Hyperglycemia is otherwise a condition where the level of sugar is too high due to lack of insulin in a body. Associated with diabetes, hyperglycemia can lead to vomiting, excessive thirst, rapid heartbeat, hunger, vision problems and other symptoms. Neglecting hyperglycemia can lead to serious health problems. Types of Diabetes   * There are three main type of diabetes: Type 1, Type 2 and gestational diabetes (“Types of Diabetes”).   * Type 1 diabetes is caused by autoimmune reaction that prevent realization of insulin in a body. Estimated 5-10% of people who have diabetes have type 1.   * Type 2 diabetes is caused by a body’s disability to control normal blood sugar level. Most people with diabetes have type 1 diabetes.   * Gestational diabetes develops in pregnant women who have never had diabetes. It leads to high risks of health problems for a baby. After birth, the diabetes stops, but mother has chances to develop type 2 diabetes. Type 1 and Type 2   * Similarities:       + Type 1 and Type 2 diabetes both occur when the body cannot store and use glucose.       + Both can lead to complications, such as cardiovascular disease, kidney disease, vision loss and other diseases.       + Both types diagnose with A1C or glycated hemoglobin test.   * Differences:       + People with Type 1 do not produce insulin, while the ones with Type 2 do not respond to it or make not enough insulin.       + The cause of Type 1 is the immunes system that attacks insulin-producing beta cells. Type 2 is caused by insulin resistance, the body unable to use insulin.       + Type 2 is more common that Type 1 diabetes.       + Type 1 cannot be prevented, while it is possible to lower risks of Type 2. (“Types of Diabetes”). Risk Factors of Type 2 If a person:   * is over overweight;   * is 45 years or older;   * has a family member with Type 2 diabetes;   * is not physically active;   * has ever had gestational diabetes;   * is African American, Hispanic/Latino American, American Indian, or Alaska Native, Pacific Islander or Asian American. He or she has higher risks of developin
