Stinky poop happens when bacteria in your gut produce gases like hydrogen sulfide, indole, and skatole during digestion. These compounds create the rotten egg smell you notice.
Your gut microbiome contains thousands of bacterial species that break down food. When these bacteria digest proteins and sulfur-containing foods, they release foul-smelling gases. The more protein and sulfur in your diet, the stronger the odor.
