What is growth hormone?

Growth hormone is crucial for normal growth and development.

It determines how the body is built and how it functions.

In addition to causing children to grow taller, growth hormone plays a number of other vital roles, including:

  • Ensuring strong, healthy bones
  • Regulating the body’s metabolism, specifically the balance between muscle and fat
  • Developing and maintening the body’s organs
  • Promoting general well-being and energy levels

Growth hormone works by causing other hormones and growth factors to be produced in the body. These growth factors, along with growth hormone itself, travel through the bloodstream and cause growth and development to occur throughout the body.

In particular, they act on a part of the bones called the growth plates, which is where bone growth occurs. Growth hormone and growth factors cause the cells in these growth plates to multiply, thus adding to the length of the bone. And this increase in the length of the bones, particular the long bones in the legs, causes a child to grow taller.
