**Abstract**

Growth hormone deficiency is one of the most common causes of short stature in response to growth hormone therapy, and deficiency occurs as a result of either a decrease in the pituitary hormones themselves, which is called hypopituitarism, or a deficiency of hypothalamus. Stunting is a condition that worries many parents because if the body's growth hormone deficiency is not diagnosed and the appropriate treatment is not taken early, which leads to a high body mass index, that is, weight gain after puberty, high fat and future risks. For type 2 diabetes, diabetes, insulindependent heart disease, atherosclerosis and other diseases, the incidence of this deficiency in European societies is about 4000/1 births which is comparable with the proportion in Iraq but increasing the incidence. This study was conducted to investigate the effect of growth hormone therapy on carbohydrate metabolism where growth hormone affects the shape and function of the developing body and apart from these functions such as stimulating growth, it has distinctive effects on the metabolism and energy, and plays a role in regulating blood sugar levels.
