Sudden increase in farting may be due to physiological factors such as diet, or pathological factors such as gastroenteritis, irritable bowel syndrome and peptic ulcer. 1. Physiological factors: If you have recently eaten a lot of onions, sweet potatoes, beans and other gas-producing foods, or high protein foods such as beef and mutton, or greasy and other indigestible foods, it will lead to an increase in the amount of gas produced in the intestines, resulting in an increase in the number of sudden farts. 2. Pathological factors: gastrointestinal diseases such as irritable bowel syndrome, peptic ulcer, inflammatory bowel disease, intestinal flora imbalance, etc., will affect the digestion, absorption and peristaltic function of the gastrointestinal tract, so that the food in the gastrointestinal tract stays longer, and the decomposition of the gas produced by the increase in the number of sudden increase in farting, which may be accompanied by abdominal pain, abdominal bloating, acid reflux, belching (hiccups), nausea, vomiting and other discomforts. If the patient suddenly farts more and accompanied by abdominal discomfort, it is recommended to consult a doctor in a timely manner to identify the cause of the disease and carry out targeted treatment to avoid delaying the condition.
