Gas is perfectly natural, but excessive gas, accompanied by bloating or distension, can be painful, interfere with daily activities, or cause embarrassment. A few simple lifestyle measures will help you get rid of it.
Gas in the gut: a fermentation problem
Gas in the small intestine or colon is usually caused by digestion or fermentation of undigested food, such as plant fibers or certain sugars (carbohydrates), by bacteria in the colon. Gas can also form when your digestive system does not completely break down certain components of foods, such as gluten or sugar in dairy products and fruits.
Other sources of intestinal gas may include:
- – Poor carbohydrate absorption, which can upset the balance of helpful bacteria in your digestive system
- – Constipation, the longer food remains in your colon, the more time it has to ferment
- – A digestive disorder, such as lactose or fructose intolerance or celiac disease
– Food residue in your colon
– A change in the bacteria in the small intestine
