When “a fat ruin all, thin that is beautiful” has become the creed of women’s beauty, many women in pursuit of good-looking and all kinds of weight loss to become thin. But the weight loss is excessive, thin into the “bone essence”, a lot of diseases also appeared. For example: uterine prolapse, cervicitis Without a sufficient amount of fat protection, the uterus is prone to fall from its normal position along the vagina, the cervix prolapses, or even out of the vaginal opening, the formation of the uterine prolapse that we have talked about, and may also lead to serious cervical infections, or even cervicitis. Anemia The problem of unbalanced nutritional intake is common among those who are too thin. The intake of iron, folic acid, vitamin B12 and other hematopoietic substances is insufficient; due to the fact that they eat less, their basal metabolism rate is also lower than that of the general population, therefore, their intestinal and gastrointestinal motility is slower, and the secretion of gastric acid is lower, which affects the absorption of the nutrients. These are the main causes of anemia. Infertility Women should have a body fat percentage of at least 17% to maintain a normal menstrual cycle and libido level, which is the minimum fat standard for them to be able to have a healthy pregnancy, childbirth and breastfeeding in the future. Because adipose tissue processes raw materials from the adrenal cortex into estrogen, it is an important place in the body, other than the ovaries, where estrogen is produced. When body fat is low, the synthesis of estrogen and its concentration in the blood will be affected, resulting in estrogen deficiency, which is one of the key criteria for fertility.
