What are the risks of HGH treatment?

HGH treatment can cause side effects for healthy adults, including:

• A hand condition called carpal tunnel syndrome.
• High blood sugar.
• Type 2 diabetes.
• Swelling in the arms and legs called edema.
• Joint and muscle pain.
• Enlarged breasts in men, also called gynecomastia.
• Higher risk of certain cancers.

Clinical studies of HGH treatment in healthy older adults have been somewhat small and short in length. So there's little information about the long-term effects of HGH treatment.
