Gas builds up in the digestive tract through several common activities: Gastric acids breaking down food release carbon dioxide
Farting (flatulence) is the normal biological process of releasing intestinal gas through the rectum. The average person farts roughly 15 times a day, expelling between 500 and 2,000 milliliters of gas. This gas is primarily a byproduct of digestion, swallowed air, and the fermentation of food by trillions of gut bacteria. This gas is primarily a byproduct of digestion,
Gut bacteria feed on undigested carbohydrates (like fiber), producing gases such as hydrogen, methane, and nitrogen.
Certain "gas-producers" are harder to break down, including beans, onions, broccoli, cabbage, and carbonated beverages. Techniques: How to Pass Gas
