What is Endocrinology?

Endocrinology is a medical field that deals with the endocrine system. This system controls hormones in your body. Endocrinologists diagnose and treat various conditions. These conditions affect the endocrine system and cause disorders like diabetes mellitus, thyroid disorders, osteoporosis, growth hormone deficiency, infertility, cholesterol problems, hypertension, obesity, and many others.

The endocrine system operates through glands and organs that release hormones. Hormones regulate vital body functions. The Glands involved in producing hormones are the hypothalamus, pineal body, pituitary, thyroid, parathyroids, adrenals, pancreas, testes, and ovaries. Each hormone in your body has a specific role. There can be up to 40 different hormones circulating in your blood at any given time. Hormones travel through your bloodstream and reach their specific destinations, called targets. These targets are found on other endocrine glands or on organs in the body.

When a hormone reaches its target, it provides instructions. It tells that part of your body what to do, when to do it, and for how long. Hormones are often referred to as “messengers.” They facilitate communication between different parts of the body. It can be said that hormones are responsible for controlling all vital body functions, such as blood sugar control, growth, and development, metabolism, and regulation of heart rate and blood pressure. They are responsible for sexual development, function, reproduction, and mood regulation.
