The pituitary gland, located near the centre of your brain, produces the human growth hormone. It is produced at the highest level during childhood or adolescence. Our body continues to produce this hormone in short intervals during our sleep, and it does not stop when we grow older. This hormone is very important for the brain function, muscle growth, bone strength, tissue repair, metabolism and for our mental and physical health.
Once the human growth hormone is secreted, it effects the following:
- Metabolism: The fat in our body is utilized faster with the help of growth hormones. They break down the fat cells so that it is easy to utilize.
- Protein metabolism- HGH increases the rate of protein synthesis, intake of amino acids and decreases oxidation of proteins.
- Carbohydrate metabolism: the level of blood sugar is maintained at a normal level due to these growth hormones.
The effect of the human growth hormones on the body tissues can be described as building up or anabolic. Like most other proteins act, the HGH interacts with the specified receptors on the cell surface. The most common known effect of the HGH is the increase in height of the child. The simulation is done in the following mechanisms:
- The growth hormone directly stimulates multiplication and division of the important cells in the growing ends of the long bones in children.
- IFG-1 or insulin-like growth factor is hormone homologous to proinsulin. The production of IFG-1 is stimulated by these growth hormones. The target organ of this process is the liver.
