Growth hormone can promote height growth is self-evident , but in the actual process, often there are many factors prevents body react with growth hormone. Wherein the greatest impact is thyroxine, normal amount of thyroxine is necessary to maintain healthy growth . If secretion deficiency, causes the pituitary gland to stop secreting the normal amount of growth hormone , And can prevent the body’s tissues,for the hormone has been released, to respond appropriately. Conversely, if hypersecretion, will accelerate the healing of the bone marrow , the body stopped growing . You can see, thyroxine for the entire growth process always plays a limited role.Therefore, only the active cooperation of growth hormone and thyroxine, can play a role in growth in height..

Hormone is secreted by the endocrine glands , a chemicals directly into the blood . So far , about 60 hormones have been found in the body , each one has its own specific organ affected , such as the skin darkening hormones ,breasts secrete milk hormones, vascular spasm hormones . If for some reason that no secretion of hormones, it will not produce a corresponding effect . Human growth process is also a biochemical reaction in the hormone action. This slow biochemical reactions work together with several hormones in the mutual cooperation. Therefore , As long as the secretion of a hormone which has been destroyed, or they were upset in the normal human body proportions, can lead to stunted growth . Conversely, if excessive secretion of hormones , can lead to uncontrolled growth . These growth-related hormone secreted by the pituitary gland , pancreas , gonads and thyroid . So how hgh affect human height growth?

Affect the height growth is also testosterone ( a male hormone ) , secreted by the gonads of male or female , can promote bone growth and formation . Androgens in sexual maturity was most active, young people from 14 to 16 years old, You can see the most significant increase in height velocity

In addition, the height growth also depends on the support of the pancreas secretes insulin , although it itself has no direct effect on the height, but only in the insulin hormone sufficient conditions can stimulate the growth.

In the same genetic condition , why some people grow faster , some people grow slowly, while others are simply not grow ? Why some people in all aspects of growing conditions are good, but not growing taller ? In Fact, this is the body ‘s hormones to cause trouble.
