Insulin is a hormone produced by the pancreas. Insulin regulates blood glucose or blood sugar levels in the body of humans and many other mammals. A pancreas that fails to produce enough insulin is the cause of diabetes. Victims of diabetes are often prescribed periodic insulin injections to regulate their blood sugar, which reduces or eliminates their symptoms. They also may be required to obey a strict diet. Although diabetes is a manageable condition, it has no cure.
