Endocrinology is the specialty of medicine that deals with the problems, diseases and medical conditions of the endocrine system. A medical endocrinologist is a physician specializing in the complex task of diagnosing and treating hormonal disorders and other metabolic disorders.
Because endocrinologists rely on laboratory tests to assist in determining the disorders of their patients, many have backgrounds in biochemistry and research. In addition, endocrinologists usually have background training in one of a number of different medical fields such as pediatrics, internal medicine, and obstetrics and gynecology. All medical endocrinologists have an MD or an analogous medical degree and some also have a PhD or another advanced science degree.
