Growth hormone tumor, or growth hormone adenoma, is a type of pituitary tumor, which is mainly caused by tumor cells secreting too much growth hormone to affect the development of the body. Growth hormone tumor can occur in young adults, due to the excessive secretion of growth hormone, can lead to gigantism. When it develops after adulthood, it manifests as acromegaly. Growth hormone is an important hormone for human development. If it develops in adolescents, a large amount of growth hormone will induce rapid development, which is usually characterized by very high height, i.e. gigantism. If the disease develops after adulthood, the main manifestation is acromegaly, such as the bones become thicker and bigger, lips become thicker, forehead becomes wider, jaw widens, hands and feet increase in size, and even the internal organs become bigger such as the liver, heart, kidneys and so on, which causes a series of clinical symptoms. If the above symptoms occur, it is necessary to pay attention to the clinical situation and go to the hospital to do the nuclear magnetic examination of the brain, various endocrine experiments and routine physical examination in a timely manner.
