1, the harm of improper weight loss
metroptosis
Without the protection of sufficient fat, the uterus can easily descend from its normal position along the female private parts, and the cervix will droop and even protrude out of the female private parts, resulting in what we call uterine prolapse, which may even lead to cervical infection and even cervicitis.
inability to get pregnant
Medical experts pointed out that women's body fat percentage should reach at least 17% in order to maintain normal menstrual cycle and desire level, which is also the minimum fat standard for their healthy pregnancy, delivery and breastfeeding in the future. Because adipose tissue can convert the raw materials provided by adrenal cortex into estrogen, it is an important place to produce estrogen in the body except ovaries. If there is too little fat in the body, it will affect the synthesis of estrogen and its concentration level in the blood, resulting in insufficient estrogen level, which is one of the key criteria affecting women's fertility.
anaemia
Too thin people generally have the problem of unbalanced nutrient intake, and iron, folic acid, vitamin B 12 and other hematopoietic substances are insufficient. Because of eating less, the basal metabolic rate is lower than that of ordinary people, so the gastrointestinal movement is slow and the gastric acid secretion is less, which affects the absorption of nutrients. These are the main causes of anemia. In addition, malnutrition reduces the body's immunity and is prone to secondary anemia.
haematuria
Our kidneys are surrounded by a dense layer of connective tissue. Too thin people have insufficient body fat content, which leads to the relaxation of this connective tissue and the weakening of muscle strength, and cannot provide external muscle protection for the kidneys. Therefore, the kidneys are prone to droop and lead to internal venous blood exudation, hematuria, and often accompanied by waist pain.
duodenal stasis
You may not be familiar with this disease, but your thinness may be the culprit. The cross section of the duodenum is located behind the peritoneum and is the most fixed part of the digestive tract. Too thin people, the mesentery and retroperitoneal fat are scarce, and the internal organs droop, which virtually narrows the gap between the spine and the proximal end of the superior mesenteric artery, resulting in duodenal compression. Therefore, it is difficult to digest what you eat, which is manifested as abdominal fullness and discomfort, accompanied by pain or vomiting after meals. Vomiting contains bile and food eaten, and the symptoms are intermittent and recurrent.
2, the harm of excessive weight loss
Memory decline
The main motivation of 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.
lose hair
The main components of human hair are protein called fish 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 loses its luster.
In this era of popular skinny beauty, many people have not seen its fatal harm. According to an article in the British Daily Mail, the research completed by Dr. Ruth Rose of Cambridge University and her colleagues found that people with a body mass index (body mass index = the square of weight/height) below 18.5 are too thin, which will greatly increase their risk in the following seven aspects.
gastroptosis
Don't envy the female colleagues around you who are always full after eating. A few mouthfuls of rice can cope with a lunch. Only she knows how much pain her stomach suffers every day: loss of appetite and always feeling flatulence and pain. If you do a painful gastroscopy for this, the diagnosis may be: gastroptosis. Yes, when the human body is too thin, the abdominal wall 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.
cholelith
Our bile is secreted by the liver, which 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.
