Excessive farting can be caused by several factors including diet, eating habits, food intolerance, stress, and gastrointestinal conditions. Common causes are eating gas-producing foods like beans, cruciferous vegetables, and dairy; swallowing excess air while eating or drinking quickly; drinking carbonated beverages; and having food intolerances such as lactose intolerance. Stress can also increase farting due to swallowing more air or through conditions like irritable bowel syndrome (IBS). Additionally, underlying digestive issues such as IBS, celiac disease, or slow intestinal motility may lead to increased gas production and farting. If excessive farting is accompanied by other symptoms like abdominal pain, diarrhea, or sudden changes in bowel movements, it is advisable to see a healthcare provider for evaluation.
