Human growth hormone (HGH) therapy is a prescription treatment for people with a medically diagnosed growth hormone deficiency, most often diagnosed in childhood or through specific pituitary and endocrine testing in adults. It is not an approved treatment for the normal decline in growth hormone that occurs with aging, and it is not a weight-loss, muscle-building, or anti-aging product. It carries real risks and requires diagnosis and ongoing supervision by a physician.
What growth hormone does
Human growth hormone is produced by the pituitary gland. It contributes to childhood growth and, throughout life, plays a role in muscle and bone maintenance, tissue repair, and metabolism. Growth hormone levels change across the lifespan and generally decline with age. This gradual, age-related decline is a normal physiological process, not in itself a disease, and it is not an indication for growth hormone therapy.
What growth hormone therapy actually treats
Growth hormone therapy uses synthetic somatropin to treat a diagnosed growth hormone deficiency. Diagnosis is made by a physician using clinical assessment and specific laboratory testing, not by symptoms alone.
In children
Physicians may prescribe growth hormone for children with conditions such as diagnosed growth hormone deficiency, Turner syndrome, and chronic kidney disease affecting growth. In children with a confirmed deficiency, treatment can support height progression toward the expected range [1].
In adults
In adults with a confirmed growth hormone deficiency (for example, following pituitary disease, surgery, or radiation), physician-supervised therapy is used to address the specific clinical consequences of that deficiency. Treatment decisions, dosing, and monitoring are individualized and managed by an endocrinologist or appropriately qualified physician.
An important boundary: growth hormone is sometimes misused for muscle-building, athletic performance, or cosmetic anti-aging purposes. These are not approved uses, they are not supported by adequate evidence, and they carry meaningful health risks.
Risks and side effects
Growth hormone therapy is not risk-free, which is why it is prescription-only and requires monitoring.
Commonly reported side effects include joint and muscle pain, fluid retention and swelling (edema) in the arms and legs, and carpal tunnel syndrome; these tend to occur early in treatment and often ease within the first couple of months [2].
More serious concerns include reduced insulin sensitivity and a higher risk of elevated blood sugar, and, in some populations, concerns relating to abnormal cell growth and cardiovascular effects [2]. Because of this risk profile, therapy is appropriate only after a confirmed diagnosis and only under ongoing medical supervision.
Who is evaluated for growth hormone therapy
Growth hormone therapy is considered only for people with a diagnosed deficiency, confirmed through appropriate testing:
- Children with a diagnosed growth disorder such as growth hormone deficiency.
- Adults with a confirmed growth hormone deficiency established through endocrine evaluation.
Symptoms such as fatigue, difficulty building muscle, or changes in body composition are common and have many possible causes. They are not, on their own, evidence of growth hormone deficiency, and they are not a reason to start growth hormone therapy.
Supporting your health through lifestyle
The following general habits support overall metabolic and hormonal health for most people. They are not a treatment for, or an equivalent substitute for, a diagnosed medical deficiency:
- Regular strength training and physical activity.
- Consistent, good-quality sleep.
- A balanced diet with adequate protein and micronutrients.
- Stress management, since chronically elevated cortisol affects many hormonal systems.
If you are experiencing persistent fatigue, unexplained changes in body composition, or other ongoing symptoms, these are worth discussing with a licensed healthcare provider, who can determine whether any testing is appropriate for you.
When to speak with a provider
If you have symptoms that concern you, speak with a licensed healthcare provider. Growth hormone deficiency is diagnosed clinically and through specific testing, and any decision about growth hormone therapy is a medical one made with a physician.
