Diabetes is a disease that is characterized by too much glucose (sugar) in the bloodstream. It occurs when the pancreas, a gland behind the stomach, does not produce enough insulin. In type 1 diabetes, the body cannot make insulin.
In type 2 diabetes, the body does not make enough insulin or use the insulin well enough to keep the body working well. Most people with diabetes have type 2 diabetes. Many don’t know they have it. Type 2 diabetes is usually associated with obesity... The test used to measure your control over time is the hemoglobin A1c test (A1c).
Insulin is produced by special cells in the pancreas, a large organ located behind the stomach. Insulin helps the body use and store glucose (sugar), which is produced during the digestion of food. Insulin is secreted into the blood at each meal and allows the body to use glucose as energy to fuel basic daily functions like moving and breathing.
