The causes of bloating and frequent farting are both physiologic and pathologic. Physiological causes include irregular diet, eating gas-producing food, etc. Pathological causes include irritable bowel syndrome. 1. Physiological causes: irregular diet, eating gas-producing food (such as radish, onion), etc., can lead to increased peristalsis of the gastrointestinal tract, incomplete digestion of food, and increased gas production. 2. Pathological causes: Irritable bowel syndrome may have symptoms such as abdominal distension and active bowel sounds, and frequent farting due to abdominal distension, which can be clarified through colonoscopy combined with medical history and physical signs. For the case of abdominal distension and frequent farting, it is recommended to consult a doctor to clarify the cause with the necessary tests.
