The pituitary gland is a small, pea-sized organ located at the base of the brain that has an enormously important role in regulating our bodies. Often referred to as the "master gland," it secretes hormones that control key functions including growth, metabolism, reproduction, mood, and tissue function.
The pituitary gland is divided into two main lobes:
| Hormone | Function |
|---|---|
| Growth hormone (GH) | Stimulates growth of bones and tissues |
| Thyroid stimulating hormone (TSH) | Stimulates the thyroid gland |
| Adrenocorticotropic hormone (ACTH) | Stimulates the adrenal glands |
| Follicle stimulating hormone (FSH) | Regulates ovulation and testosterone production |
| Luteinizing hormone (LH) | Regulates ovulation and testosterone production |
| Hormone | Function |
|---|---|
| Oxytocin | Stimulates uterine contractions during childbirth and milk let-down during breastfeeding |
| Antidiuretic hormone (ADH) | Regulates fluid balance in the body |
The pituitary gland works closely with the hypothalamus, a region of the brain that connects the nervous system to the endocrine system. The hypothalamus produces hormones that either stimulate or inhibit pituitary hormone release, creating a negative feedback loop that keeps hormone levels balanced.
Some key facts about the pituitary gland:
Pituitary gland disorders can lead to a variety of health problems. Common disorders include:
Symptoms of pituitary problems depend on which hormones are involved but may include irregular periods, infertility, headaches, vision changes, excessive thirst/urination, abnormal growth, and more.
Fortunately, pituitary disorders can often be managed with medication, surgery, radiation therapy, or hormone replacements. Close monitoring by an endocrinologist is recommended.
The pituitary gland plays a crucial role in regulating various bodily functions through the hormones it secretes.
