Pituitary Adenomas

 Pituitary nodules are growths in the pituitary gland. The pituitary gland, or master gland, is located at the base of the brain and controls growth, metabolism, and reproduction. The gland produces several hormones, including corticotropin (ACTH), which causes the adrenal glands to produce corticosteroids, and thyroid-stimulating hormone (TSH), which causes the gland to produce corticosteroids. Thyroid that produces thyroid hormones In addition, growth hormone (GH), which regulates the body's growth, prolactin, which is necessary for breast development and milk production. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which work in sexual development and reproduction; antidiuretic hormone which are necessary for water balance and blood pressure; and oxytocin, which helps the uterus contract during childbirth. Adenomas can cause the pituitary gland to overproduce or produce little hormone. Very large tumors can press on the brain and cause headaches and other symptoms.
