There is no such thing as “farting a lot and loud but not smelly is a sign of what disease”, farting a lot and loud but not smelly is not necessarily a disease, it may be caused by physiological factors, or it may be caused by intestinal flora imbalance, acute gastroenteritis, dyspepsia and other disease factors. The loudness of farting is generally related to the amount of gas, the pressure of gas in the rectum and other factors, and the odor of farting is generally related to diet, disease and other factors. 1. Physiological factors: eating a lot of gas-producing food, such as beans, sweet potatoes and so on, will cause farting more and loud but not odor. 2. Disease factors: intestinal dysbiosis when the balance of normal flora in the intestinal tract is disrupted, an increase in gas-producing bacteria can cause farting to increase and loud but not smelly; acute gastroenteritis when the gastrointestinal peristalsis function is abnormal, resulting in farting, but not smelly, diarrhea, abdominal pain and other symptoms; dyspepsia when the gastrointestinal peristalsis is slowed down, the food in the body continues to ferment and produce gas can cause farting, but loud, but not smelly. If you have excessive farting that is loud but not smelly, you are advised to go to the hospital and ask the doctor to make a judgment and identify the cause of the problem after eliminating the physiological factors.
