About endocrinology

Your endocrine system is a network of glands that makes your hormones and is responsible for almost every cell, organ and function. If your endocrine system isn’t healthy, you may experience a wide range of problems – spanning mood, menopause, metabolism and much more.

Endocrinology is the branch of medicine that manages the endocrine system and any hormonal problems, including diabetes, thyroid, pituitary disease and osteoporosis.

Issues with your endocrine system can arise at any stage of life.
