Endocrinology is a branch of biology and medicine that deals with the endocrine system, its diseases, and its specific secretions known as hormones. It is also concerned with the integration of the events of development, proliferation, growth and differentiation, as well as the psychological or behavioral activities of metabolism, growth and development, tissue function, sleep, digestion, respiration, excretion, mood, stress, lactation, movement, reproduction and hormone-driven sensory perception.
Hormones are released in one part of the body, travel into the bloodstream and have an effect on another part of the body. This helps different parts of the human body to communicate with each other. Hormones are secreted by endocrine glands, such as the pituitary, thyroid or adrenal glands.
Endocrinologists are doctors who specialize in diagnosing and treating health conditions related to problems with the body's hormones, hormone glands, and related tissues.
