Growth hormone therapy refers to the use of growth hormone (GH) as a prescription medication—it is one form of hormone therapy. Growth hormone is a peptide hormone secreted by the pituitary gland that stimulates growth and cell reproduction. In the past, growth hormone was extracted from human pituitary glands. Growth hormone is now produced by recombinant DNA technology and is prescribed for a variety of reasons. GH therapy has been a focus of social and ethical controversies for 50 years. This article describes the history of GH treatment and the current uses and risks arising from GH use. Other articles describe GH physiology, diseases of GH excess (acromegaly and pituitary gigantism), deficiency, the recent phenomenon of HGH controversies, growth hormone in sports, and growth hormone for cows. Medical uses
HGH deficiency in children
Growth hormone deficiency is treated by replacing growth hormone.Lonapegsomatropin was approved for medical use in the United States in August 2021. HGH deficiency in adults
The Endocrine Society has recommended that adult patients diagnosed with growth hormone deficiency (GHd) be administered an individualized GH treatment regimen. With respect to diagnosis, their guidelines state that "adults patients with structural hypothalamic/pituitary disease, surgery or irradiation in these areas, head trauma, or evidence of other pituitary hormone deficiencies be considered for evaluation for acquired GHd" and that "idiopathic GHd in adults is very rare, and stringent criteria are necessary to make this diagnosis.
Because in the absence of suggestive clinical circumstances there is a significant false-positive error rate in the response to a single GH stimulation test, we suggest the use of two tests before making this diagnosis. "GH replacement therapy can provide a number of measurable benefits to GH-deficient adults. These include improved bone density, increased muscle mass, decrease of adipose tissue, faster hair and nail growth, strengthened immune system, increased circulatory system, and improved blood lipid levels, but long term mortality benefit has not yet been demonstrated.A peer-reviewed article published in 2010 indicates that "Growth hormone (GH) replacement unequivocally benefits growth, body composition, cardiovascular risk factors and quality of life. Less is known about the effects of GH on learning and memory." Other
As of 2004, GH has been approved by the U.S. Food and Drug Administration for treatment of other conditions such as:

In adults, wasting (or cachexia) caused by AIDS. Turner syndrome epitomizes the response of non-deficient shortness. At doses 20% higher than those used in GH deficiency, growth accelerates. With several years of treatment the median gain in adult height is about 2–3 in (5.1–7.6 cm) on this dose. The gains appear to be dose-dependent. It has been used successfully in toddlers with Turner syndrome, as well as in older girls. Short-stature homeobox gene deficiency 
Chronic kidney failure results in many problems, including growth failure.
