Why do some people's breath smell like poop?


Bad breath stinks, but what can you actually do about it? Chew some gum? Suck on a mint? These strategies offer some benefit, but they’re short lasting.  And brushing your teeth? Very important, but not that effective as a treatment by itself, according to a scientific review by researchers in Brazil. You need a complete strategy.  So let’s start with the root cause of bad breath: volatile sulfur compounds (VSC). While they sound more like fumes you’d emit from your butt than your mouth, scientists say these substrates are what typically lead to halitosis.
