The average person passes gas up to 20 times a day; farting is a normal part of the digestive process. However, certain factors can make you produce extra-smelly farts, such as the foods you eat, constipation, or food intolerances. Whether the smell resembles rotten eggs or another pungent odor, having smellier-than-usual farts can be embarrassing but usually isn't harmful.
