What is HGH
Human growth hormone, usually termed HGH, is a natural hormone that is present in all humans. It is produced in the pituitary gland of the brain, the master gland of the body located in the endocrine system. This hormone is similar to estrogen and testosterone. HGH stimulates growth in children and plays an important role in adult metabolism. In humans, the amount of growth hormone after the age of 21 to 31 falls about 14% per decade. Human growth hormone deficiency exists when this hormone is absent or produced in inadequate amounts. Too much or too little growth hormone can result in various medical problems.
For centuries, scientists assumed that human growth hormone had a significant role only till the time of puberty and that it was not a component in growth or any other function after that. Recent studies reveal HGH is involved in many physiological processes throughout life, including the turnover of muscle, bone and collagen, the regulation of fat metabolism and the maintenance of a healthier body composition in later life.
Diet, exercise and sleep patterns are influential in the secretion of the hormone. Human growth hormone secretion can be triggered by a number of natural stimuli, the most influential of which are sleep and exercises. Deficiency of HGH produces different problems at various ages. In children, growth failure, short stature and delayed puberty are the major symptoms of HGH deficiency. In adults the effects of deficiency are more difficult to detect, and may include deficiencies of strength, energy, and bone mass, in addition to increased cardiovascular risk. This hormone is vital for a number of reasons in older individuals. The main feature is that it can slow down the aging process.
Excess growth hormone in children causes gigantism, which is characterized by tall stature. In adults, increased levels of HGH can lead to swelling of the soft tissues in the body, excessive hair growth, high blood pressure, a greater propensity to sweat and abnormal growth of the hands, feet and face.
Human growth hormone replacement therapy is suggested for children and adults with scientifically proven growth hormone deficiency. Synthetic human growth hormone made through genetic engineering became extensively obtainable after 1985.
