What is my belly button smells like poop?

As an AI language model, I cannot diagnose medical conditions or provide medical advice. In general, if you are experiencing an unusual or foul odor coming from your belly button, it could be a sign of an infection or other medical issue. It is always best to consult with a healthcare provider for proper diagnosis and treatment. In the meantime, you can practice good hygiene by keeping the area clean and dry, avoiding harsh soaps or cleaning agents, and wearing loose-fitting clothing to allow for ventilation.
