Pituitary Disorders Clinic

This small organ-about the size of a pea-is known as the body's master gland. Located at the base of the brain, it makes:

  • Prolactin, which stimulates milk production after childbirth
  • Growth hormone, which stimulates growth in childhood and is important for maintaining muscle and bone mass
  • Adrenocorticotropin (ACTH), which stimulates production of cortisol by the adrenal glands
  • Thyroid-stimulating hormone (TSH), which stimulates the thyroid gland
  • Antidiuretic hormone (ADH), which regulates water balance in your body
  • Luteinizing hormone (LH), which regulates testosterone in men and estrogen in women
  • Follicle-stimulating hormone (FSH), which promotes sperm production in men and stimulates the ovaries to enable ovulation in women

Often, the cause of pituitary disorders is pituitary gland tumors that interfere with the normal formation and release of hormones. These tumors are fairly common in adults. They are not brain tumors and are not cancer. The tumors can cause production of too much or too little, in either case creating a hormonal imbalance.

Our team members treat pituitary gland disorders by hormone therapy, surgery or radiation therapy.
