What is diabetes?
Type I diabetes is a disease that affects the way the body uses food. In a person with Type I diabetes, the body destroys the cells in the pancreas that produce insulin. Insulin is a hormone that regulates the level of sugar in the blood. Type I diabetes is also called immune-mediated diabetes, and was formerly known as insulin-dependent diabetes.

In Type II diabetes, once known as non-insulin-dependent diabetes, the pancreas does not make enough insulin or the body cannot use it properly. We will not discuss Type II diabetes any further.

Scientists do not know what causes Type I diabetes, but there appears to be a genetic component to the cause. Other factors also are likely to increase the risk for getting diabetes. Diabetes is not contagious.

Symptoms and diagnosis:
Signs and symptoms of diabetes are:
