Growth hormone treatment

Growth hormone treatment 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.

Growth hormone deficiency is treated by replacing GH. All GH prescribed in North America, Europe, and most of the rest of the world is a human GH, manufactured by recombinant DNA technology. As GH is a large peptide molecule, it must be injected into subcutaneous tissue or muscle to get it into the blood. Nearly painless insulin syringes make this less trying than is usually anticipated, but perceived discomfort is a subjective value.

When treated with GH, a deficient child will begin to grow faster within months. Other benefits may be noticed, such as increased strength, progress in motor development, and reduction of body fat. Side-effects of this type of physiologic replacement are quite rare.
