What are the 5 gases that come out of farts?

The five main gases that can be found in flatulence are nitrogen, hydrogen, carbon dioxide, methane, and sulfur dioxide. Nitrogen makes up the majority of the gas, while hydrogen and methane are produced by gut bacteria during digestion. Carbon dioxide is also formed during the breakdown of food, and sulfur dioxide is responsible for the characteristic odor of some farts. The specific composition can vary based on diet and individual digestive processes.
