A member asked:

Is it true that taking a proton pump inhibitor for acid reflux can cause bad breath by allowing bacteria / fungi to accumulate in high ph environment?

Not really: I have a lot if patients on ppi therapy and this is definitely not a common complaint. If this happens it is rare.

Doubtful: Much more likely that acid reflux will cause bad breath, as well as increase risk of oral pharyngeal cancer & ulcers. I'd take the prescribed medication unless advised otherwise by your doctor.
