All About Human Growth Hormone

Human growth hormone (HGH) is made all through out each individual’s life but is made in greater quantities in children and young adults. It is a protein substance, which is normally released during the first few hours of sleep and also as a response to stress. It is important in both children and adults as it stimulates growth in the young and plays a major role in the adult metabolism. The human growth hormone was first isolated by scientists in 1956 but wasn’t identified until 1972. Before the development of genetic engineering, the only source of the human growth hormone was humans. In order to provide people who had a growth hormone deficiency with the substance, the pituitary gland had to be removed from corpses and processed in order for the hormone to be extracted. Although, the human growth hormone has been successfully aiding the proper growth in children with a deficiency since 1959, all supplies are now manufactured using artificial procedures to avoid the risk of transmitting Cretzfeld-Jakob Disease (CJD). CJD is a side effect of the human growth hormone when it was made form the pituitary glands of human corpses. CJD is caused by an infective agent, which can be passed on from the corpse to the patient receiving the HGH and has an incubation period of up to 30 years. In recent years, 26 cases out of 7700 people who received the hormone as children, before 1977 have been identified as having CJD. Others who received the hormone before 1985 may still not know whether or not they will develop the disease in the future. Those who are affected can claim for compensation. It is because of concerns of transmitting CJD that this method hasn’t been used since the synthetic hormone was identified in 1985.

In 1959 it was considered a great medical breakthrough when children with a reduced height condition who normally grew to a height of around 130 cm by 18 years of age could reach a height of the average 180 cm when injected with HGH. It is now used in a number of other ways since it can be made in unlimited quantities in the lab. One such use is to reverse muscle deterioration in AIDS patients.

Many athletes consider using human growth hormones to increase the size and strength of their muscles to be an illegal performance enhancer. However, modern research has caused many people to doubt whether the hormone can in fact improve performance. HGH has also been promoted as an anti-aging treatment, although once again there is a lack of scientific evidence to support these claims.

High levels of human growth hormone can lead to high blood pressure, swelling of the body’s soft tissue and excessive sweating and hair growth, which is a known condition named acromegaly. Abnormally high levels of the hormone are usually due to benign tumours on the pituitary gland. People who inject the hormone without having a deficiency risk causing diabetes.
