Growth hormone fuels childhood growth and helps maintain tissues and organs throughout life. It’s produced by the pea-sized pituitary gland — located at the base of the brain. Beginning in middle age, however, the pituitary gland slowly reduces the amount of growth hormone it produces.
This natural slowdown has triggered an interest in using synthetic human growth hormone (HGH) as a way to stave off some of the changes linked to aging, such as decreased muscle and bone mass.
If you’re skeptical, good. There’s little evidence to suggest human growth hormone can help otherwise healthy adults regain youth and vitality. In fact, experts recommend against using HGH to treat aging or age-related conditions.
Do some adults need human growth hormone?
Yes. Adults who have true growth hormone deficiency — not the expected decline in growth hormone due to aging — might be prescribed synthetic human growth hormone by their doctors.
Growth hormone deficiency might be caused by a benign tumor on the pituitary gland (pituitary adenoma). It also might be caused by treatment of an adenoma with surgery or radiotherapy.
For adults who have a growth hormone deficiency, injections of human growth hormone can:
Increase exercise capacity
Increase bone density
Increase muscle mass
Decrease body fat
Human growth hormone is also approved to treat adults with AIDS- or HIV-related muscle wasting.
What can human growth hormone do for healthy adults?
Studies of healthy adults taking human growth hormone are limited. Although it appears that human growth hormone can increase muscle mass and reduce the amount of body fat in healthy older adults, the increase in muscle doesn’t translate into increased strength. It isn’t clear if human growth hormone might provide other benefits to healthy adults.
