One of the most important components required for normal functioning of the body are hormones. They are instrumental in smooth functioning of the body including digestion, respiration, growth, reproduction, sleep, and even our moods. Produced in the endocrine glands that are located in various parts of the body, hormones are chemical messengers that trigger many body functions. And, when the endocrine gland has any disease, it results in hormonal disorders.

Hormones travel throughout the body, yet they can trigger action only on a specific organ. Upon reaching the target organ, these hormones initiate or inhibit certain functions of the body. For example, the thyroid-stimulating hormone produced in the pituitary gland acts on the thyroid glands and influences the production of thyroid hormones. Aldosterone produced in the adrenal glands acts on the kidneys and regulates electrolyte balance and helps in balancing fluids.
