Normally, blood glucose levels are tightly controlled by insulin, a hormone-produced by the pancreas. Insulin lowers the blood glucose level. When the blood glucose elevates (for example, after eating food), insulin is released from the pancreas to normalize the glucose level. In patients with diabetes, the absence or insufficient production of insulin causes hyperglycemia. Diabetes is a chronic medical condition, meaning that although it can be controlled, it lasts a lifetime.
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 26 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.
