What is Diabetes UK?

Diabetes is a chronic disease, which occurs when the pancreas does not produce enough insulin, or when the body can’t effectively use the insulin it produces. Insulin is a hormone that regulates blood sugar. Raised blood sugar (hyperglycaemia) is a common effect of uncontrolled diabetes. Over time uncontrolled diabetes leads to serious damage to many of the body's systems, especially the nerves and blood vessels.
