Diabetes

Diabetes mellitus, often simply referred to as diabetes—is a group of metabolic diseases in which a person has a high blood sugar, either because the body does not produce enough insulin or because cells do not respond to the insulin that is produced.

Diabetes may increase the risk of complications in different parts of the body. One common complication is neuropathy, and it usually begins in the longest nerves and therefore affects feet first. Neuropathy means that nerves have become damaged, resulting in loss of sensation.
