2, gastroptosis. When the human body is excessively emaciated, the abdominal wall in the body is slack and the abdominal muscles are weak, which leads to the weakness of the muscles and ligaments that suspend and fix the position of the stomach, and the abdominal pressure drops, so the physiological position of the whole stomach will be reduced and the gastric peristalsis will be weakened, thus causing gastroptosis.

3, gallstones. Bile is secreted by the liver and contains cholesterol, bile salts, calcium and lecithin. And they keep a certain proportion. People who are too thin generally have insufficient calorie intake, so the consumption rate of fat precipitated in body tissues is accelerated, and cholesterol moves with it, resulting in its content in bile increasing, becoming sticky, precipitating crystals and forming stones.

4. infertility. Under normal circumstances, women can only maintain normal sexual characteristics if their body fat content exceeds 22%. Because fat is an important place for women to produce estrogen, the estrogen converted by mature women accounts for one-third of the total estrogen in the body. This is also the minimum fat standard for their healthy pregnancy, childbirth and breastfeeding in the future.

5. Osteoporosis. The incidence of hip fracture in thin women is higher than that in standard weight women 1 times. This is because the estrogen level in thin people is insufficient, which affects the combination of calcium and bone and cannot maintain normal bone density, so osteoporosis and fractures are prone to occur.

6, anemia. People who are too thin generally have the problem of unbalanced nutrient intake. Iron, folic acid, vitamin B 12 and other hematopoietic substances are not enough, and nutrients are not absorbed enough. These are the main causes of anemia.

7. Memory loss. The thin human body is short of fat intake and storage, and the body is short of nutrition, which seriously damages brain cells and directly affects memory, so we become more and more forgetful.
