The pituitary gland is a small, bean-shaped gland located at the base of the brain behind the eyes. Despite its small size, the pituitary gland is often referred to as the "master gland" because it produces hormones that regulate critical bodily functions and work with the hypothalamus to control most of the other hormone-secreting glands in the body.
The pituitary gland has two main lobes that secrete different hormones:
- The anterior lobe produces hormones that regulate several physiological processes including growth, metabolism, and reproduction. Key hormones secreted by the anterior pituitary include:
- Growth hormone (GH) - stimulates growth of bones and tissues
- Thyroid-stimulating hormone (TSH) - regulates production of thyroid hormones
- Adrenocorticotropic hormone (ACTH) - stimulates the adrenal glands to produce cortisol
- Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) - regulate development of eggs and sperm and sex hormone production
- The posterior lobe stores and releases two hormones produced by the hypothalamus:
- Oxytocin - stimulates uterine contractions during childbirth and milk ejection during breastfeeding
- Antidiuretic hormone (ADH) - regulates water balance in the body
The pituitary gland works closely with the
hypothalamus, which connects the endocrine system and nervous system. The hypothalamus produces hormones that either stimulate or inhibit hormone production in the anterior pituitary. This feedback loop allows the body to maintain homeostasis.
Pituitary disorders can occur if the gland produces excessive or deficient amounts of one or more hormones. Common disorders include:
- Pituitary adenomas - benign tumors that may overproduce hormones
- Pituitary apoplexy - bleeding into a pituitary tumor
- Hyperpituitarism - overproduction of pituitary hormones
- Hypopituitarism - underproduction of pituitary hormones
Symptoms vary depending on which hormones are involved but may include vision problems, headaches, fatigue, weight changes, infertility, and more. Treatment also varies but may involve medication, surgery, radiation therapy, or hormone replacement therapy.
If you suspect a pituitary issue, consult an
endocrinologist for evaluation and treatment. Early diagnosis is key, as pituitary problems can disrupt many bodily processes when hormones are out of balance. Restoring proper hormone levels can dramatically improve symptoms and prevent complications.
