Growth hormone (GH), also known as somatotropin, is produced by the pituitary gland. Despite its name, it does much more than promote growth in children and adolescents.
What Growth Hormone Does:
GH stimulates growth of bones and tissues during childhood and adolescence. Throughout life, it helps maintain healthy body composition by promoting protein synthesis, breaking down fat for energy, and regulating metabolism. It works closely with insulin-like growth factor 1 (IGF-1).
Release Pattern:
GH is released in pulses throughout the day, with the largest surge occurring during deep sleep. This is why quality sleep is essential for growth and repair. Exercise, stress, and low blood sugar also trigger GH release.
GH Through Life:
Production peaks during puberty and gradually declines with age. This natural decrease contributes to age-related changes like reduced muscle mass, increased body fat, and decreased bone density. Deficiency in children causes growth failure, while in adults it can cause fatigue, decreased muscle mass, and emotional issues.
