Insulin information from trusted sources:
To help evaluate insulin production, diagnose an insulinoma, and to help determine the cause of hypoglycemia
Diabetes means your blood glucose, or blood sugar, is too high. If you can't control your diabetes with wise food choices and physical activity, you may need diabetes medicines. The kind of medicine you take depends on your type of diabetes, your schedule, and your other health conditions. With Type 1 diabetes, your pancreas does not make insulin. Insulin is a hormone that helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood. If you have type 1 diabetes, you will need to take insulin.
