A proton pump inhibitor (PPI) is a type of medicine that helps your tummy when it is sore. Your tummy is called your stomach or your belly. Sometimes when you eat or drink things that are not good for your tummy, your stomach makes too much acid. Acid is like a strong sour juice that can hurt your tummy.
PPIs are like tiny helpers that go into your tummy and turn off some little pumps that make acid. These pumps are called proton pumps. By turning them off, the PPIs help reduce the amount of acid in your tummy, and that makes your tummy feel much better.
Sometimes your doctor might give you a PPI if they think you have too much acid in your tummy. They might also give it to you if you have something called reflux. Reflux is when some of the stuff in your tummy comes up into your throat and makes you feel like you want to cough or clear your throat. PPIs can help stop this from happening too.
It's important to take PPIs just like your doctor tells you to, usually with food. You should not take more or less than what your doctor says because it can make your tummy feel worse. And remember, you should always talk to a grown-up or a doctor if you have any questions or concerns about taking medicine.
