Frequent smelly farts may be related to indigestion, intestinal inflammation, constipation and other factors. Specifically as follows: 1. Indigestion: Due to the slowing down of gastrointestinal peristalsis, food is not discharged in time. Fermentation in the body produces a lot of gas, and the gas is accompanied by the smell of rotting food, which leads to the frequent release of smelly farts. 2. Intestinal inflammation: when there is a bacterial infection in the intestines, it will stimulate the intestinal wall to secrete inflammatory substances. When bacteria gather in the intestine, it will lead to fermentation of food and produce a lot of gas, which is accompanied by bad smell. 3. Constipation: food residues can not be discharged in time, piling up in the intestinal tract, and constantly fermenting to produce a large amount of ammonia, which leads to frequent smelly farts. In short, there are many factors that cause frequent smelly farts, such as intestinal cancer, intestinal flora disorders, etc. Normal people may also occasionally appear similar situation. If you have frequent smelly farts for a long time, it is recommended to consult a doctor in time to identify the cause of the problem and then treat the symptoms.
