The medical specialty and scientific field focused on the study of hormones, endocrine glands, and their related disorders and functions in living organisms.

Overview

Endocrinology is a branch of medicine and biology that investigates the complex system of hormones, endocrine glands, and their effects on bodily functions. This field encompasses both the clinical practice of diagnosing and treating hormonal disorders and the scientific research of endocrine system mechanisms.

Key Components

Endocrine Glands

The major endocrine glands in the human body include:

Pituitary gland - often called the "master gland"
Thyroid gland
Pancreas - crucial for diabetes mellitus regulation
Adrenal glands
Gonads (ovaries and testes)
Parathyroid glands

Hormones and Signaling

Endocrine signaling occurs through various types of hormones:

Clinical Applications

Common Disorders

Endocrinologists diagnose and treat various conditions including:

Diagnostic Methods

Modern endocrinology employs various diagnostic techniques:
