What Is Diabetes?

Diabetes affects the way the body uses food. It is caused by a lack of insulin, a hormone made in the pancreas that is essential for converting energy from food. Insulin is necessary for the body to process nutrients (carbohydrates, fats, and proteins), and its absence causes high sugar (glucose) levels in the blood.There are two types of diabetes:In type 1 diabetes, which usually starts in childhood, the pancreas stops making insulin altogether. It is also called insulin-dependent diabetes.In type 2 diabetes, which starts in adulthood (and in some teenagers) the body still makes some insulin. But it doesn't make enough insulin, or the body can't use it properly. It is also called non-insulin-dependent diabetes.
