Yes they prevent acid but that's masking the root symptom (not enough and not low enough PH to stimulate closure of the LES). Not having enough might seem like it fixes it in the short term, but it causes knock-on effects that mean your food isn't being digested properly and you're more prone to bad bacteria making it's way to the small intestine. Once it gets there, it's very hard to get rid of so be careful on PPIs!
