Human growth hormone (HGH): Does it slow aging?

What are the risks of HGH treatment?

HGH treatment might cause a number of side effects for healthy adults, including:

  • Carpal tunnel syndrome
  • Increased insulin resistance
  • Type 2 diabetes
  • Swelling in the arms and legs (edema)
  • Joint and muscle pain
  • For men, enlargement of breast tissue (gynecomastia)
  • Increased risk of certain cancers

Clinical studies of HGH treatment in healthy older adults have been relatively small and short in duration, so there's little to no information about the long-term effects of HGH treatment.
