Growth hormones HGH have many functions. They directly stimulate the reproduction of growth cells in children. This will help them grow taller. Growth hormones HGH also stimulate bone growth by stimulating activity in the osteoblast and chrondocytes. Growth hormones also produce an insulin-like substance which is used by the liver. Growth hormones also stimulate the growth of all internal organs except the brain. Growth hormones HGH also increase calcium retention, muscle mass and protein synthesis. Growth hormones also play a role in stimulating the immune system.

Growth hormone HGH deficiency can lead to reduced growth, short stature and even sexual immaturity. This can be treated by external injection of HGH. Excessive secretion of growth hormones HGH can lead to thickening of the jaw, insulin resistance and abnormal growth, referred to as pituitary gigantism. This condition is usually treated by removing the growth hormone tumors in children. These tumors are very rare in children, but when they are apparent, they must be removed surgically.HGH can be used to treat short stature caused due to reasons other than growth hormone HGH deficiency. The results are not as successful as when treating short stature due to growth hormone HGH deficiency, but it makes a difference to the patients.

HGH can be used to increase muscle mass and reduce body fat. HGH can also be used to maintain the muscle mass from wasting in AIDS patients. HGH is also used as an anti-aging agent. It delays the symptoms of aging and is a great help to menopausal women.
