Endocrinologists specialize in the diagnosis and treatment of disorders of the endocrine system, including diabetes, Cushing syndrome, and growth abnormalities.

When we think of "messages" being sent throughout the body, we usually think of the nervous system. But there is another communication system in the body, called the endocrine system.


The endocrine system is made up of the ductless glands, including the pituitary gland, the adrenal glands, the thyroid gland, the parathyroid glands, the islet cells in the pancreas, the ovaries (in women), and the testes (in men). These glands secrete hormones that travel as messengers throughout the body to direct and integrate a vast number of bodily functions.

Endocrinologists must complete an internship and a residency in internal medicine, followed by two years of training in endocrinology.
