Endocrinology is a medical specialty that focuses on the diagnosis, treatment, and management of disorders related to the endocrine system. The endocrine system comprises a network of glands that produce and release hormones, which are chemical messengers that regulate various physiological processes in the body. Endocrinologists are medical doctors who specialize in endocrinology and work to maintain hormonal balance and address conditions that arise due to hormone-related imbalances.
