Endocrinologists are specialists in hormonal problems and know the glands that produce these hormones. These specialists are very suitable in treating diabetes as this disease is given by the pancreas’ lack of production (which is a gland) and insulin (which is a hormone). The pancreas produces the insulin we need to regulate blood sugar. When a person has diabetes, the pancreas either does not produce insulin or does not work properly. An endocrinologist treats especially patients with type 1 diabetes.
