Some people turn to HGH in hopes that it will keep them feeling and looking youthful. But experts say that hope is unfounded. And worse, these products can be harmful. HGH, produced by the pituitary gland, spurs growth in children and adolescents. It also helps to regulate body composition, body fluids, muscle and bone growth, sugar and fat metabolism, and possibly heart function.
Because the body's HGH levels naturally decrease with age, some so-called antiaging experts have speculated and claimed that HGH products could reverse age-related bodily deterioration. But these claims are unproven. The use of HGH for antiaging is not FDA-approved.
Possible side effects of HGH use include:
nerve, muscle, or joint pain
swelling due to fluid in the body's tissues (edema)
carpal tunnel syndrome
numbness and tingling of the skin
high cholesterol levels
HGH can also increase the risk of diabetes and contribute to the growth of cancerous tumors.
