Why are you farting alot?

Answer 1

Farting happens because bacteria in the digestive tract produce hydrogen or methane gas as a waste product of their own metabolism. Different foods have different effects on these bacteria. Beans notoriously produce gas because they include a kind of carbohydrate that human beings don't digest, which therefore becomes a rich source of food for bacteria. Onions often stimulate bacterial gas production as well. For people who are lactose intolerant, lactose (also known as milk sugar) creates a huge amount of gas because the lactose intolerant person cannot digest it (due to a lack of the lactase enzyme) and therefore the bacteria do. If you have problems after drinking milk or eating other dairy products, you are probably lactose intolerant.
