Endocrinology is a specialty of Medicine, some would say a subspecialty of Internal Medicine, which deals with the diagnosis and treatment of diseases related to the endocrine glands and tissues that secrete hormones.
What is the Endocrine System? The human endocrine system consists of a number of glands. These glands produce and secrete hormones which control the body’s metabolism, growth, sexual development and function. When the hormones leave the glands they enter the bloodstream and are transported to organs and tissues in every part of the body.
