Explanation

A suppository is a medicine that goes up your bum, instead of in your mouth.

It's usually a small capsule, but sometimes it can be a liquid.

Doctors call this liquid an enema. Sometimes an enema can be difficult to hold in, because it feels like you need to go to the toilet.

If this is a problem, the enema might come as a foam instead of a liquid. You might need suppositories if you have Crohn's disease.
