What Do Endocrinologists Do?

Endocrinologists are qualified to assist patients with the medical specialty of Endocrinology, which focuses on endocrine and metabolic disorders. The endocrine system is composed of organs (glands) that produce hormones that regulate certain body functions. Metabolism consists of the biochemical processes in the body that cause the breaking down of some substances (e.g. food) and the building up of others (e.g., fat, muscle or bone).

Endocrinologists primarily diagnose, evaluate, and treat conditions related, but not limited, to:

• diabetes
• obesity
• hormone issues (including estrogen and testosterone levels)
• decreased libido (sex drive)
• erectile dysfunction
• menopause
• osteoporosis
• thyroid disorders
• parathyroid disorders
• adrenal disorders
• pituitary disorders
• abnormal growth and development in children

In addition, the field of practice may overlap other medical specialties in the evaluation and treatment of patients who have various conditions including:

• high blood pressure (hypertension)
• abnormal cholesterol and/or triglyceride levels
• kidney stones
• infertility
• polycystic ovarian syndrome
• female hirsutism (excessive facial/body hair)
