Fart Smell Could Save Your Life! Eating Healthy Can Still Cause Smelly Gas - Doctor Warns: 'One Type of Odor' May Indicate Colon Cancer
Everyone passes gas daily, and the odor of flatulence can be an indicator of health. Dr. Huang Yu-Chun, a colorectal surgeon, explains that passing gas 5-20 times a day is normal. Foods like asparagus, spinach, and garlic produce hydrogen sulfide, which can lead to foul-smelling gas - like rotten eggs. However, if the odor is unusually strong or smells like rotting meat or sewage, it could signal gut imbalance, constipation, or even colon cancer.On her YouTube channel, Dr. Huang notes that most gas is odorless, consisting mainly of carbon dioxide and hydrogen. The smell comes from methane and compounds like hydrogen sulfide and methanethiol. She warns that persistent foul-smelling gas, especially with symptoms like watery stool, frequent small farts, and fatigue, may be signs of colorectal issues and warrants medical attention.
