Endocrinology is a branch of biology and medicine dealing with the endocrine system, its diseases, and its specific secretions known as hormones. Endocrinologists have the training to diagnose and treat hormone imbalances and problems by helping to restore the normal balance of hormones in the body. The common diseases and disorders of the endocrine system that endocrinologists deal with include diabetes mellitus, as well as adrenal, pituitary, and thyroid disorders, among others.
