When you're sick, your farts change. The smell shifts. The sound shifts. Even the timing shifts. And believe it or not, those changes are telling you something real about what's happening deep inside your gut.

In this video you'll discover why diarrhea farts come out wet, loud, and sour, while constipation farts turn dry, quiet, and shockingly potent. You'll travel inside your intestines to meet the trillions of bacteria that shape every fart you make, learn how the speed of your digestion changes the exact gases your body produces, and find out when a change in your gas is actually your body asking for help. By the end, you'll never hear a fart the same way again.
