People farting all the time may be caused by physiological factors such as eating easily gas-producing foods and swallowing a lot of air, or it may be caused by other reasons such as irritable bowel syndrome, intestinal dysbiosis, and indigestion. 1. Physiological factors: If you often eat soy, onions and other foods that are easy to produce gas, or eat too fast, talk during meals may lead to swallowing too much air. At this time, a large amount of gas will be produced in the stomach, and the human body will have the manifestation of farting all the time. 2. Irritable bowel syndrome: The cause of irritable bowel syndrome is still unclear, and it is considered to be caused by abnormal gastrointestinal dynamics, visceral hypersensitivity, and intestinal infections. Patients will have abdominal distension, abdominal pain, diarrhea, constipation, etc. If the patient’s abdominal distension is obvious, he/she may have the symptom of old fart. 3. Intestinal dysbiosis: Intestinal dysbiosis may be caused by intestinal immune dysfunction, abnormal intestinal dynamics, and drug factors. After eating, the food cannot be completely digested and absorbed, and the undigested food will be decomposed by the intestinal bacteria, thus producing gas in the gastrointestinal tract. At this time, the patient will not only have the symptom of farting a lot, but also have the performance of abdominal pain. 4. Other: Farting can also be caused by indigestion, chronic pancreatitis and other diseases. It is recommended that the symptoms of farting should be treated in time, and the doctor will choose the appropriate measures to treat the patient’s condition.
