The pituitary gland is a small, pea-sized organ located at the base of the brain that plays a crucial role in regulating critical bodily functions and general health. As the master endocrine gland, it governs the activity of most other glands in the endocrine system and produces hormones that trigger essential physiological processes.
Some key facts about the pituitary gland:
- It is divided into two lobes - the anterior and posterior lobes - with each lobe responsible for releasing specific hormones
- The anterior lobe produces trophic hormones that target other endocrine glands, including thyroid-stimulating hormone, adrenocorticotropic hormone, follicle-stimulating hormone, luteinizing hormone, growth hormone and prolactin
- The posterior lobe releases oxytocin and antidiuretic hormone which control childbirth/lactation and water balance in the body
- The pituitary gland works closely with the hypothalamus in the brain to integrate the endocrine system and is often referred to as the "master gland of the body"
What are some key functions of pituitary hormones?
- Growth hormone stimulates growth and cell reproduction
- Thyroid-stimulating hormone controls thyroid activity and metabolism
- Adrenocorticotropic hormone regulates the adrenal glands and stress response
- Luteinizing hormone and follicle-stimulating hormone govern sexual development and function
- Prolactin stimulates breast milk production during lactation
- Oxytocin induces uterine contractions during childbirth and lactation
- Antidiuretic hormone manages fluid balance in the body
Given its integral role in coordinating hormones, disorders of the pituitary gland often cause
hormonal imbalances and other system-wide effects. Common disorders include:
- Pituitary tumors like prolactinoma
- Overproduction or underproduction of specific pituitary hormones
- Pituitary failure (hypopituitarism)
- Growth hormone excess (acromegaly) or deficiency
Luckily, many pituitary abnormalities are treatable, especially when caught early. Medications can correct hormonal imbalances while surgeries are available for pituitary tumors. Consult an endocrinologist or make an appointment at
