Diabetes, the most common disorder of the endocrine (hormone) system, occurs when blood sugar levels in the body consistently stay above normal. It affects more than 30 million people in the U.S. alone.

Diabetes is a disease brought on by either the body’s inability to make insulin (type 1 diabetes) or by the body not responding to the effects of insulin (type 2 diabetes). It can also appear during pregnancy. Insulin is one of the main hormones that regulates blood sugar levels and allows the body to use sugar (called glucose) for energy. Talk with your doctor about the different types of diabetes and your risk for this disease.
