The role of growth hormone

The body produces human growth hormone (HGH, or GH). This protein is vital not only in childhood but also during adulthood. The pituitary gland is responsible for the production of growth hormones. It is also known as the "master gland" because it releases many hormones that regulate the activity of other glands. The hypothalamus is a part of the brain that sends signals to the pituitary to produce growth hormones. This hormone then functions in other parts of your body via the bloodstream.

While scientific research has often focused on growth hormone's role in the growth process of the human body, it is also important for adult metabolism.

Growth hormone and its role in the growth

Many factors can influence growth, as most people know. Growth can be affected by nutrition, overall health, and hormones such as GH. Growth hormone isn't the only hormone that plays a role in growth. Other pituitary hormones, such as thyroid-stimulating hormone, Adrenocorticotropic Hormone, luteinizing Hormone, and follicle-stimulating Hormone, can indirectly influence growth via other glands. All hormones can influence growth but GH is the main growth regulator.

Growth hormone is responsible for stimulating bone and tissue growth in children. Growth hormone stimulates bone growth by stimulating the epiphyseal expansion plate. GH triggers the release of insulin-like growth factor I (IGF-I), which stimulates bone, muscle, and other tissue growth in response to GH. This regulates the release from the pituitary. The growth hormone is also important for proper bone density. This is important both in childhood and adulthood.

This mechanism, along with other complex bodily processes sustains human development from infancy through adulthood.

A clinical trial with 13 healthy men between 50 and 70 years old showed that GH stimulated collagen synthesis, which resulted in an increase in strength.

A second study of 16 healthy people over 60 showed that growth hormone accelerated protein synthesis, increasing strength and muscle mass.

For this reason, athletes and bodybuilders often use GH as a performance-enhancing drug.

People with growth hormone deficiencies tend to have lower muscle mass and strength than people with normal levels.

Acromegaly can be caused by excessive growth hormone. Acromegaly patients have large muscles but not enough strength. Uneven muscle composition can hinder power output.
