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 is reduced and the gastric peristalsis is weakened, which leads to gastroptosis.

Hazard 2, infertility

Medical experts pointed out that women's body fat percentage should reach at least 17% in order to maintain normal menstrual cycle and sexual desire level, which is also the minimum fat standard for their healthy pregnancy, delivery and breastfeeding in the future.

Being too thin will not only affect the fertility of women, but also affect the fertility of men. A study involving 53 16 men at the University of Aberdeen in the United Kingdom found that being too thin in men would lead to poor sperm quality, which in turn would affect fertility.

Hazard 3, anemia

Too thin people usually have the problem of unbalanced nutrient intake, eating less, lower basal metabolism than ordinary people, slower gastrointestinal movement and less gastric acid secretion, which affects the absorption of nutrients and directly causes anemia.

Hazard 4, memory loss

The main motivation for brain work comes from fat, which can stimulate the brain, accelerate the brain's ability to process information and enhance short-term and long-term memory.

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.

Hazard 5, hair loss

The main components of hair are protein and trace elements such as zinc, iron and copper. Too thin people have insufficient supply of body fat and protein, so their hair frequently falls off, and their hair color gradually turns yellow, thin and dull.

Harm 6, the mortality rate increases.

According to a study published in the Journal of Clinical Endocrinology and Metabolism, among Japanese patients with type 2 diabetes, people with body mass index between 18.5 and 24.9 kg/m2 seem to have the lowest mortality rate, while the mortality rate of obese people has not decreased, but the body mass index.
