GH is the medical abbreviation for growth hormone, which increases the cellular response to amino acids to promote protein synthesis and promotes the growth and development of bones, muscles and organs as well as the division, proliferation and protein synthesis of cells in other tissues.GH induces the production of growth mediators, namely insulin-like growth factor and IGF2, in target cells.GH shifts the body’s energy source from glucose metabolism to fat metabolism, which facilitates Elevated GH predisposes to diseases associated with pituitary tumors, such as acromegaly and pituitary gigantism, and diseases associated with non-pituitary tumors, such as diabetes mellitus, renal insufficiency, and pancreatic cancer. decreased GH predisposes to pituitary dwarfism and hypopituitarism, and decreased GH due to non-pituitary diseases predisposes to cirrhosis of the liver and brain tumors near the pituitary gland.
