Here are possible reasons why your fart smells terrible

The bugs in your gut
During digestion, gut bacteria produce sulfur-containing compounds like hydrogen sulfide that create a stench in your gas. The food you eat can increase the bacteria that live in your colon and that can affect your farts.

Sulfur-rich foods
Foods rich in sulfur can make your farts smell like rotten eggs. Sulfur-rich foods include garlic,onions, legumes, dried fruits, beer, wine, cabbage and nuts. Animal protein rich in sulfur like eggs, meat and fish could also be the reason.

Lactose intolerance
Lactose passes through the small intestine without being absorbed, travelling downstream to the colon where bacteria feast on it which result to smelly gas, since milk and certain cheese have a high sulfur content. You can also be intolerant to other sugar like sucrose and fructose.

Beans are rich source of protein, antioxidants, vitamins and minerals and could also make you fart. Beans contain raffinose, a group of sugars that are at least partially responsible for the bloating and gas that can occur after a bean meal.

Sugar alcohol
Sugar alcohols like sorbitol and xylitol canbe found in diet drinks, sugar free candy and some chewing gum. These sweetners cannot be fully absorbed by the body, so they travel to the colon where they can contribute to awful-smelling gas. Giving extra care to your food will help you know if it suagr alcohol are causing your stinky fart or candy.


When you are constipated, feaces hangs around your colon for too long and then bacteria can realy travel down and cause lots of gas.

Certain prescription drugs, vitamins and supplements can make your fart smelly. How badly that gas stinks varies from one person to another.
