Who is an endocrinologist?

The most common diseases treated by an endocrinologist include diabetes mellitus type 1 and type 2, Thyroid disorders, hypothyroidism, hyperthyroidism, and goiter.

An endocrinologist is a specialist doctor who treats imbalances of hormones or the endocrine system of the body. An endocrinologist is trained for almost two to three years in endocrinology after completing four years of medical schooling and three years of post-graduation in internal medicine.

Hormones are secreted by the endocrine glands of the body. Different hormones have different actions. Each hormone acts on a specific body part. They help in the growth and development of the body and regulate various bodily functions. Some hormones help in your growth and development, some help in regulating your blood pressure and temperature, and others help a woman to conceive or become pregnant.

Endocrinology is a branch of the medical field that deals with diseases related to hormones and the glands that secrete them (endocrine glands). The glands that secrete the hormones include:

  • Pancreas: A gland located in your abdomen that makes insulin and glucagon.
  • Thyroid: A butterfly-shaped gland in your neck that controls your metabolism, energy, and brain growth and development.
  • Pituitary gland: A pea-sized gland located at the base of your brain that controls all the other hormones.
  • Adrenal glands: A pair of glands, one on each side of the abdomen, located on the top of your kidneys. They exert control on your blood pressure, metabolism, stress response, and sex hormones.
  • Parathyroid glands: Four small glands in your neck that control the level of calcium in your blood.
  • Hypothalamus: A small gland located at the base of your brain that controls body temperature, hunger, and thirst.
  • Ovaries: Reproductive glands (gonads) in females that contain eggs.
  • Testes: Reproductive glands (gonads) in males that contain sperms.
  • Pineal gland: A gland found near the center of the brain that may be linked to sleep patterns.
  • Thymus: A gland in the upper part of your chest that helps in the development of the body’s immune system during the early stages of your life.
