Farting loudly in the morning is not necessarily a problem, may be due to diet and other physiological factors, but may also be indigestion, intestinal flora imbalance, constipation and other gastrointestinal tract pathology. 1. Physiological factors: intestinal peristalsis will be relatively slow at night when you go to bed, if you eat a lot of easy-to-gas-producing food, such as sweet potatoes, beans, etc., or laugh or talk loudly during dinner, resulting in more gas entering the gastrointestinal tract, in the morning when you get up, gastrointestinal peristalsis resumed, you may fart very loud situation. 2. Indigestion: patients with indigestion are usually accompanied by gastrointestinal dysfunction such as abnormal digestion and absorption or peristalsis of the gastrointestinal tract, resulting in the food eaten at dinner cannot be digested, absorbed and emptied in time, accumulating in the gastrointestinal tract and decomposing to produce a large amount of gas under the action of intestinal bacteria, which may cause loud fart in the morning. 3. Intestinal flora imbalance: when the beneficial bacteria in the patient’s intestinal tract decreases and the harmful gas-producing bacteria increases, it will increase the gas produced by the decomposition of food in the gastrointestinal tract, resulting in loud farts in the morning. 4. constipation: constipated patients feces and food residues, etc. in the intestinal tract stays longer, by the intestinal flora decomposition of gas will increase, the night intestinal peristalsis slows down, so that the gas accumulates in the gastrointestinal tract, resulting in the morning gastrointestinal tract to restore peristalsis, fart very loud. There are many other causes of loud farting, such as gastroenteritis, gastrointestinal polyps, gastrointestinal tumors, etc. If the patient has a long term or repeated presence of loud farting in the morning, it is recommended to consult a doctor in time to avoid delaying the condition.
