The causes of farting without stinking farts are dietary factors, intestinal flora imbalance, gastrointestinal tract dysfunction and so on. 1. Dietary factors: due to eating a lot of gas-producing food, such as sweet potatoes, groundnuts, soybeans, etc. When gas-producing food enters the gastrointestinal tract, it will be digested and absorbed, generating a large amount of carbon dioxide gas, resulting in an increase in the patient’s exhaust, but with little flavor. 2. Intestinal flora imbalance: due to the increase of beneficial flora in the intestinal tract and the decrease of harmful flora, resulting in intestinal dysfunction and increase of gas production, which causes the patient’s exhaust to increase, but these gases do not have any flavor. 3. Gastrointestinal dysfunction: Due to the dysfunction of gastrointestinal tract, the secretion of digestive enzymes and gastric acid is reduced, resulting in the food not being fully digested and absorbed, and staying in the intestinal tract for a longer period of time. Fermentation occurs and a large amount of gas is produced, which triggers the patient to experience increased anal exhaust, but the farts do not necessarily smell bad. If the patient appears to fart not smelly but more farts, it is recommended that the patient go to the hospital in time. Improve the relevant examination, clarify the cause of the disease, and follow the doctor’s instructions for treatment.
