The sudden increase in exhaustion is caused by improper diet, imbalance of intestinal flora, and indigestion. Many people have increased exhaustion because of dietary problems, such as a diet often eat potatoes, yams and other foods. It will be because the food contains a lot of sugar, fiber, in the intestinal tract in the accumulation of gas caused by the intestines. Soybean products contain a large amount of soybean oligosaccharides, and the lack of enzymes in the intestine to break down oligosaccharides can lead to a large amount of gas in the intestine, resulting in increased exhaustion. There are a large number of flora in the intestine, but some of them are harmful, and when there is an imbalance in the flora, the harmful bacteria will overgrow. This not only affects the absorption function of the intestine, but also reacts with food residues to produce gas, resulting in a sudden increase in gas emissions. In case of indigestion, half-digested food enters the intestinal tract, which will not only cause irritation to the intestinal tract but also produce gas by bad fermentation, thus inducing increased exhaust.
