HUMAN GROWTH HORMONE (HGH)
Human growth hormone
(HGH) is produced by the pituitary gland, which
is a pea-sized organ located at the base of the brain. In addition to spurring
childhood growth, it also helps regulate:
- Fat metabolism
- Bone growth
- Muscle growth
- Brain function
- Blood sugar
- Sleep
- Memory
As we age, however, the
amount of HGH produced by the pituitary gland decreases. This has prompted an
interest in producing the hormone synthetically to treat aging or age-related health issues.
But not only is there
little evidence to support the claim that synthetic HGH can counteract the
effects of aging,
experts recommend against using human growth hormone treatments because of its
associated risks.
What is human growth hormone treatment used for?
Growth hormone treatment
involves administering injections of synthetic HGH to adults who have a growth
hormone deficiency. HGH may be caused by a benign growth (tumor) on the pituitary gland or treatments
such as radiation or surgery.
Generally, HGH treatment
is used to treat:
- Muscle wasting associated with human immunodeficiency virus infection
and acquired immune deficiency syndrome (HIV/AIDS)-related
growth hormone deficiency
- Short bowel syndrome (inability of the intestine to
absorb nutrients)
- Genetic disorders, including:
- Turner's syndrome (a genetic disorder that affects a
girl's development)
- Prader-Willi syndrome (a genetic
disorder that affects muscle tone, sex hormones, and hunger)
- Chronic kidney
disease
- Babies born
with low birth weight
For adults with a growth
hormone deficiency, growth hormone treatment is used to:
- Improve endurance or exercise capacity
- Increase bone mass or density
- Increase muscle mass
- Decrease body fat
However, there are
limited studies on the benefits of growth hormone treatment in healthy adults.
Though some studies have shown that the treatment helps increase muscle mass in
older adults, there is no improvement in their strength.
What are the risks of taking growth hormones?
Approved forms of human
growth hormone are available only as injections. HGH is also sold in pill form,
but there is no evidence that these supplements are effective. Excess use of
injections or ingestion of these pills can cause:
- Swelling in the limbs
- Joint pain
- Muscle pain
- Carpal tunnel syndrome (a condition
in which the pressure on the median nerve in your wrist causes pain, tingling, and numbness in the hand)
- Type II diabetes
- Gynecomastia (breast enlargement in
men)
- Increased risk of certain cancers
To avoid these side
effects, growth hormones should be used with caution. Do not use injections
without getting a prescription from your doctor, and you should check in
regularly with your doctor while you are taking it.
If you do not have
growth hormone deficiency and want to improve your health, it’s best to find
other ways to do this, such as eating a balanced diet and exercising regularly.
