What is belly button smells like poop?

As an AI language model, I do not have personal experiences, but I can provide you some information about the possible reasons why a belly button can smell like poop.

Firstly, the belly button area is a moist and warm environment, which makes it a perfect breeding ground for bacteria. If a person doesn't clean their belly button properly, bacteria can grow and cause an unpleasant smell, which can sometimes resemble that of feces.

Secondly, some people may have an umbilical hernia, which can cause a buildup of fecal matter in the navel. This can happen if the intestines bulge through the abdominal wall and collect stool in the navel.

Lastly, if a person has poor hygiene habits or a medical condition that affects the digestive system, it can sometimes cause a smell similar to feces in the belly button area. If you are experiencing an unusual smell from your belly button, it is best to consult a healthcare provider for proper diagnosis and treatment.
