"Can HGH injections anti-aging and build muscle?" "Can children with insufficient height take HGH?" In recent years, Human Growth Hormone (HGH) has frequently appeared in public view, with endless related questions. Reporters learned from multiple endocrine specialist institutions around the world that HGH, as a strictly controlled prescription drug, is not a "panacea". Its clinical application has clear definitions, and only specific groups can use it under professional guidance.
"Can HGH injections anti-aging and build muscle?" "Can children with insufficient height take HGH?" In recent years, Human Growth Hormone (HGH) has frequently appeared in public view, with endless related questions. Reporters learned from multiple endocrine specialist institutions around the world that HGH, as a strictly controlled prescription drug, is not a "panacea". Its clinical application has clear definitions, and only specific groups can use it under professional guidance.
Core Positioning and Clinical Application Boundaries of HGH
HGH is a peptide hormone secreted by the anterior lobe of the human pituitary gland. It dominates growth and development in childhood and maintains tissue repair and metabolic balance in adulthood. "Its application has always centered on 'pathological deficiency' or 'adjuvant treatment of specific diseases'. Abuse by healthy people is not only ineffective but may also cause serious risks such as diabetes and joint damage," Dr. Mark Wilson, Director of the Department of Endocrinology at Johns Hopkins Hospital in the United States, emphasized in an interview.
Target Group 1: Children and Adolescents with Growth and Development Disorders
This is the most important clinical application scenario of HGH, which is mainly applicable to growth retardation caused by insufficient HGH secretion or related diseases. It specifically includes three types of situations: First, primary growth hormone deficiency (GHD). Children with this condition have abnormal pituitary function, and their annual height growth is usually less than 4 cm, with bone age lagging behind chronological age by more than 2 years. After standardized treatment with recombinant HGH, the annual height growth can be increased to 8-10 cm in the first year. According to data from the European Society for Paediatric Endocrinology, about 150,000 such children worldwide receive HGH treatment every year, and their adult height can reach the genetic potential height.
Second, hereditary growth disorders, such as Turner syndrome (X chromosome deletion in females) and Prader-Willi syndrome (obesity-related growth retardation caused by abnormal genetic imprinting). Taking Turner syndrome as an example, if children start HGH treatment before the age of 10, combined with adolescent sex hormone intervention, their final height can be increased by an average of 10-15 cm. Third, growth retardation caused by acquired diseases, such as chronic renal failure and severe malnutrition. On the basis of etiological control, HGH can be used as an adjuvant treatment.
Target Group 2: Adults with Severe HGH Deficiency
HGH secretion naturally decreases in adulthood, but there is an essential difference between "physiological decline" and "pathological deficiency". Adult HGH deficiency defined clinically is mostly caused by pituitary tumor surgery, hypophysitis, head trauma, etc. Patients not only experience symptoms such as fatigue, decreased muscle mass, and visceral fat accumulation but may also be accompanied by metabolic problems such as decreased bone mineral density and insulin sensitivity.
"Diagnosis requires professional tests such as insulin hypoglycemia test and arginine stimulation test, and symptoms must be highly consistent with test results," Professor Li from the Department of Endocrinology at Peking Union Medical College Hospital explained. The quality of life of such patients can be significantly improved after HGH replacement therapy. A 2024 study by the Japanese Society of Endocrinology showed that after 1 year of standardized medication, diagnosed patients had an average increase of 3.2 kg in muscle mass, a 15% decrease in visceral fat, and a 2.1% increase in bone mineral density.
Target Group 3: Patients Receiving Adjuvant Treatment for Specific Diseases
In the treatment of some special diseases, HGH can play an adjuvant role. For example, patients with HIV-related muscle wasting syndrome have protein metabolism disorders due to viral infection, and HGH can promote muscle synthesis and relieve emaciation symptoms; burn patients using HGH during the recovery period can accelerate wound healing and reduce the risk of infection; patients with short bowel syndrome can improve intestinal absorption function through HGH. However, such applications must follow the principle of "low dose and short-term use" and must be carried out simultaneously with the treatment of the primary disease.
Clear Contraindications: People Who Absolutely Cannot Use HGH
The contraindications for HGH use are also clear, including patients with active tumors (HGH may promote tumor cell proliferation), patients with severe diabetes (HGH can increase blood sugar), patients with uncontrolled acute infection or trauma, and patients with severe liver and kidney dysfunction. In addition, blind use of HGH by healthy children due to "height anxiety" may lead to premature closure of epiphyseal plates, which instead affects the final height; abuse by healthy adults pursuing "anti-aging and muscle building" has been listed as an illegal act in many countries.
Expert Warning: Three Evaluations Must Be Conducted Before Medication
Dr. Mark Wilson emphasized that HGH medication requires three evaluation processes: "etiological evaluation + functional testing + individual adaptability analysis": "First, clarify whether there is a disease that causes HGH deficiency or requires adjuvant treatment; second, quantify HGH levels through professional testing; third, formulate a personalized plan based on age, underlying diseases, liver and kidney function, etc." He also reminded that HGH treatment requires regular re-examinations, and the dosage should be adjusted according to the efficacy and side effects. Long-term follow-up monitoring is required after stopping the medication.
