The recent frequent exhaustion is related to the recent improper diet, imbalance of intestinal flora, and irritable bowel syndrome. Some foods contain a large amount of starch and protein, and frequent consumption of such foods will increase the number of exhausts because of the large amount of carbon dioxide gas produced during the digestion of starch and protein, and after stopping the intake of such foods, the exhaust reaction will also decrease. Some people eat and drink a lot of food, and at the same time, a lot of gas will enter the digestive system with the food, so the exhaust will also increase. When there is an imbalance of intestinal flora, there will be a large number of harmful bacteria in the intestinal system, especially when there is an excessive growth of gas-producing bacilli, which will react with food residues and produce more gas. During the onset of irritable bowel syndrome, not only does the intestinal peristalsis become hyperactive and produce large amounts of gas, but also the function of the intestine is impaired and it is not able to absorb the gas in the intestinal cavity, so the number of outgassing increases.
