    Why does my poop burn? It’s a question many people have, but most don’t ask it aloud. The truth is that burning poop happens to most people at some point. Often it goes away on its own; other times, it may be due to a more serious condition.

    Burning poop: possible causes 

    Does it hurt when you poop? Painful bowel movements, clinically referred to as dyschezia, are never pleasant. A painful bowel movement can have many related symptoms, including stomach cramping, gas, pelvic pressure, bloating, bleeding, and burning. 

    Burning poop can happen when the mucosal lining of your rectum is inflamed. Issues like diarrhea, constipation, bowel disease, and even sexually-transmitted infections like chlamydia can all cause inflammation that makes it painful to poop. 

    If it hurts when you poop, it could be due to a number of reasons. Read more to learn about the possible causes of burning poop, from the non-threatening to the serious.

    Constipation

    If you’re experiencing painful bowel movements, one of the main reasons could be constipation. Constipation can leave you feeling “backed up” because you’re not pooping as much as you should be. One to three spontaneous bowel movements daily is considered normal. If you’re having fewer than three bowel movements per week, you’re constipated.

    Some people experience constipation before their period, when the progesterone spikes after ovulation. If constipation is a PMS symptom, it will usually go away within a couple of days. Dairy products, coffee, tea, and alcohol can make constipation worse.
