Human growth hormone (HGH) is a hormone produced in the pituitary gland that plays an important role in growth and development. As we age, HGH production naturally decreases, which can lead to changes in body composition and function.
Some signs that may indicate an HGH deficiency include increased body fat, decreased muscle mass and strength, reduced exercise capacity, changes in cholesterol levels, and emotional issues like depression and anxiety. Blood tests can help determine if HGH levels are abnormally low.
HGH therapy has been shown to reduce body fat and improve lean body mass when used to treat diagnosed deficiencies. The changes are gradual over months.
Clinical studies have found modest improvements in muscle strength and exercise capacity with HGH therapy. Benefits appear over the first 6 months.
By stimulating bone regeneration, HGH therapy can lead to small increases in bone mineral density. This may lower fracture risk.
Some people report feeling more energetic, motivated, and positive while undergoing HGH therapy. But findings vary across studies.
HGH therapy can help lower LDL ("bad") cholesterol while raising HDL ("good") cholesterol. The changes tend to be modest over 6-12 months.
By improving energy, body composition, and cholesterol, HGH therapy may have secondary benefits for emotional health. But more research is still needed in this area.
While an overview of HGH therapy has been provided, specific medical claims and recommendations cannot be made here. Those interested should speak to their healthcare provider about whether testing and treatment are appropriate for their individual health situation. Lifestyle improvements should be considered first before pursuing hormone therapies.
While often associated with illegal performance enhancement, HGH therapy is also legally prescribed to help children with growth disorders grow taller. When used properly under a doctor's care, it allows these children to reach normal heights they could not achieve on their own.
