This is why I get a bit annoyed when friends and random people in the pub tell me that using a ppi longterm is bad for my health. I had severe ulceration of the oesophagus before I saw my GP and was told, after an endoscopy, that if it was left there was a high chance it would lead to cell changes and then cancer. I have a hiatus hernia so the acid goes where it shouldn't. Not much I can do to completely stop that happening. I hope you are ok Jules.
