Diabetes is a group of metabolic diseases that are characterized by high levels of glucose, or blood sugar. It is caused by the pancreas not producing a sufficient amount of insulin (Type 1), the cells in the body not properly responding to the insulin produced (Type 2), or occurs during pregnancy (gestational). While the cause of Type 1 Diabetes is unknown, Type 2 is commonly caused by excessive body weight and not enough exercise.
Symptoms include frequent urination, increased thirst and hunger. Type 1 Diabetes must be managed with insulin injections, and Type 2 may be treated with medications (with or without insulin).
