To lose weight needs to be weighed

Why does the amenorrhea appear after the weight loss? Menstrual flow is a symbol of sexual maturity in women. It is the process of periodic hyperplasia and exfoliation of endometrium under the influence of ovarian hormones. It is regulated by the hormone in the body accurately. Human adipose tissue is not only a simple storage of energy, but also an important endocrine function. It can affect the female reproductive function by secreting leptin on the hypothalamus – pituitary – gonadal axis, while participating in human sex hormone metabolism in the human body, which can promote the formation of estrogen. Besides, the ovaries need to synthesize the sex hormones through the intake of cholesterol in the body. Therefore, when the body fat is lower than the normal lower limit, the synthesis of estrogen in the body can be reduced, and the decrease of estrogen level will lead to abnormal regulation between the pituitary and ovary, and then cause menstrual disorder and even amenorrhea.

Body fat plays an important physiological role in women. It should be controlled within a reasonable range. The normal body fat range of women is about 20-25%, and different races may be different. Obesity can be diagnosed when the body fat rate exceeds 30%. The maintenance of female reproductive function requires the body to maintain at least the minimum amount of fat, that is, the lower body fat rate of women, generally not less than 15%, and the low body fat rate may affect the women’s menstrual flow or even the reproductive function.

Water, lipids, protein and minerals account for 99.4% of the body composition. Currently, some components of human body can be analyzed by means of some detection methods. The biological component analysis of bioelectrical impedance is the most widely used in clinical practice. The principle of the principle is to make use of the principles of adipose tissue, muscle tissue, body moisture and so on. It can analyze the composition of body fat, muscle, bone and body moisture. We used this method to measure the body fat rate of the above female patients. The results showed that she was only 3%, far below the normal lower body fat rate of women, which was also an important cause of its amenorrhea.
