Hormones play an important role in human growth and development, the regulation of life activities and the metabolism of human substances. 1. The role of hormones in human growth and development: Hormones involved in growth and development in the body include thyroxine, growth hormone, sex hormones, etc. These hormones not only promote the increase in height and weight gain, but also promote the development of intelligence, reproductive ability and secondary sexual characteristics. When hormone levels are abnormal, abnormal developmental manifestations such as gigantism, dwarfism, cretinism and gynecomastia will occur. 2. Hormone regulation of life activities: when the human body suffers from trauma or drastic changes in the external environment, the body’s glucocorticoids, adrenaline and other hormones will increase rapidly to regulate the body’s blood circulation, respiration, urinary and digestive activities and other life activities, in order to adapt to the changes in the external environment. 3. The role of hormones on the body’s material metabolism: the metabolism of water, glucose, electrolytes and other substances in the human body depends on the regulation of hormones. For example, antidiuretic hormone can regulate the metabolism of water, insulin and glucagon can regulate the level of blood glucose, aldosterone can promote the metabolism of sodium ions and other electrolytes. If you have any of these abnormalities, or if you suspect a hormone metabolism disorder, it is recommended that you go to the hospital for prompt medical attention.
