More farts that don’t smell bad and are still loud may be caused by physiological reasons, such as dietary factors. But it may also be caused by indigestion, chronic gastritis and other pathologic reasons. 1. Dietary factors: If you eat too much gas-producing food within a short period of time, such as sweet potatoes, soybeans, etc., the digestion of these foods in the intestinal tract will produce a large amount of gas, resulting in an increase in the exhaust, the fart is still loud, but generally no odor. 2. Indigestion: If functional indigestion occurs, resulting in the intestinal tract food stays too long, breeding bacteria and flora imbalance, there will also be an increase in intestinal gas, resulting in farting and loud farts. 3. Chronic gastritis: because the gastric mucosa is in an inflammatory state, the food that enters the stomach can not be fully digested and decomposed, the intestinal tract accumulates too much food residue, and after bad fermentation produces a large amount of gas that causes farting to increase and also the phenomenon of ringing, usually without odor. The patient who has more farts without odor and also loud, should go to the regular hospital in time to find out the cause of the disease, under the guidance of professional doctors to take targeted treatment.
