Eating garlic and farting frequently may be a normal phenomenon, but frequent farting may also be caused by improper diet, gastric ulcers, intestinal flora disorders and other reasons. 1. Normal phenomenon: garlic contains a large amount of allicin, which may stimulate gastrointestinal peristalsis. In addition, garlic also contains sulfur compounds, which will be broken down by intestinal flora in the intestinal tract and produce a large amount of gas, so frequent farting caused by eating garlic is a normal phenomenon. 2. Improper diet: If you often overeat or eat too fast and too quickly, it may cause a lot of air swallowed during meals, resulting in gas entering the intestines and frequent farting, which may be more obvious after eating stimulating foods such as garlic. 3. Gastric ulcer: when patients suffer from gastric ulcer, it may affect the digestive function, resulting in food not being fully digested, causing food to remain in the stomach for a long time, and after mixing and fermentation, frequent farting, loss of appetite, abdominal distension and other symptoms, accompanied by abdominal pain and other manifestations. 4. Intestinal flora disorders: If the patient has intestinal flora disorders, it will easily lead to abnormal proliferation of gas-producing bacteria, causing an increase in the number of bacteria that break down the food to produce gas, resulting in an increase in the accumulation of gas in the intestinal tract and the phenomenon of frequent farting. After eliminating the physiological causes of frequent farting, patients should go to the hospital in time, and actively treat the cause of the disease to avoid delaying the condition.
