Bloating and farting may be caused by dietary problems, irritable bowel syndrome and intestinal flora imbalance. 1. Dietary problems: If the patient eats a lot of spicy food, easy to produce gas food such as soy, etc., it will stimulate the gastrointestinal mucosa, causing abdominal distension and increased exhaust. 2. Irritable Bowel Syndrome (IBS): If the patient has too much mental stress and is often anxious, it may lead to IBS. It affects the digestive function and makes the intestines susceptible to irritation, leading to bloating and farting. 3. Intestinal bacteria imbalance: If the intestinal flora is imbalanced, gas-producing bacilli increase, which can lead to bloating and farting. Bloating and farting may also have other causes, if the patient can not be relieved within a short time and other symptoms, should go to the hospital in time.
