In many cases, gas doesn’t have any smell, and nobody will notice—which is a good thing if you’re in public. Swallowing air usually causes this gas and is odor-free. However, if you notice that your flatulence odor is getting worse you should contact a medical professional about the bad smells.

Most of the strong smells result from sulfur chemical compounds that are made, when certain foods are consumed like eggs, meat, and some veggies.
