There is no "stool" in human body. Qingchang tea with cathartic is harmful to health

"Qingchang slimming tea" is selling well in the market Relevant advertisements said that constipation patients and beauty loving women can achieve the effect of "clearing the excrement and expelling intestinal toxins" by drinking the tea Is Qingchang tea so magical? We interviewed Liu Yecheng, chief physician of the emergency department of Peking Union Medical College Hospital According to Dr Liu, there is no such term as "stool" in both traditional Chinese medicine and Western medicine Normal people can defecate once or twice a day, once or twice a day, or even once every two to three days But more than 3 days may have the possibility of intestinal obstruction, constipation, need to come to the hospital for examination Businessmen say that "subEn" has been in the body for a long time, which is a kind of hype The gut is not a sewer and does not accumulate waste on the wall of the pipe There is regular movement of the intestine, and the movements of each segment of the intestine cooperate with each other, so there will be no long-term adhesion of some stool on the intestinal wall For example, Dr Liu said: "we make colonoscopy for patients The intestinal wall of normal people is pink A small number of people with tumors or local inflammation may have other changes There is no widespread phenomenon of" stool "and" intestinal wall blackening "that businesses say There is no "7 to 11 kg of stool in the body." There are bacteria in the normal human body, and about 30% of the fecal solid weight discharged is bacteria Having bacteria is not necessarily a bad thing Bacteria are part of the gut barrier It is called "microbial barrier" in medicine Microorganisms can help human body digest and absorb, and many people will supplement probiotics through yoghurt and so on Therefore, human health is inseparable from bacteria According to Liu, bacteria help break down food The bacteria in the colon may produce substances not needed by the human body when they decompose food, which is the "toxin" in the propaganda of the businessmen But there is no evidence that normal people's intestines absorb these toxins, causing so-called "harm." Cathartic slimming harms health the so-called "Qingchang tea" has cathartic ingredients Even with the "pure natural" gimmick, such as senna leaf price and rhubarb price are "pure natural" herbs, which are also classified as cathartic by Chinese and Western medicine So the principle of Qingchang tea is to use diarrhea to lose weight Fast passage of food through the intestine is not conducive to the absorption of nutrients, resulting in malnutrition, sallow complexion, and even dehydration Liu said that drinking this kind of tea is easy to form the dependence on cathartic In the end, if there is no cathartic, there will be no way to defecate, resulting in stubborn constipation Liu said that the use of cathartic will speed up the intestinal peristalsis, which may cause intestinal intussusception, volvulus and obstruction If the disease is serious, surgery is needed The most serious consequence of abuse of cathartic is that it will cause melanosis of colon and increase the probability of intestinal tumor Finally, he said, the human body can metabolize itself and has the mechanism of self eliminating toxin If it is not constipation (defecation once more than 3 days) or intestinal obstruction, it does not need to use external force to detoxify So don't trust the propaganda of the businessmen, which is harmful to your health.
