Endocrinologists are medical doctors who specialize in diagnosing and treating health conditions related to problems with the body’s hormones, hormonal glands, and related tissues. They have specialized training in the endocrine system and can help diagnose, treat, and manage the illnesses that can arise when hormone imbalances or endocrine gland problems occur.
Increased or decreased levels of endocrine hormone may be caused by:
- A problem with the endocrine feedback system
- Disease
- Failure of a gland to stimulate another gland to release hormones (for example, a problem with the hypothalamus can disrupt hormone production in the pituitary gland)
- A genetic disorder, such as multiple endocrine neoplasia (MEN) or congenital hypothyroidism
- Infection
- Injury to an endocrine gland
- Tumor of an endocrine gland
