Insulin-like growth factor 1, abbreviated as IGF-1, is known to regulate metabolism and promote growth and development.
Insulin-like growth factor 1 is a broad-spectrum class of growth promoters with a homologous single-chain polypeptide similar in chemical structure to insulinogen. It is usually divided into two types, IGF-1 and IGF-2. IGF-1, not only has an anabolic effect, but also promotes cell growth and differentiation. It is mainly used in children with dwarfism and tested during growth hormone therapy.
In addition, a variety of tissues, such as liver, kidney, lung, etc., can secrete insulin-like growth factor 1, the synthesis of which is regulated by growth hormone. However, growth hormone is susceptible to a variety of stress factors such as satiety, cold, exercise, etc., and is unstable in a single blood draw, whereas IGF-1 levels are more stable, which is important in diagnosing the disease.
If a patient has an abnormal insulin-like growth factor 1 value, go to the hospital promptly.
