Thank God for antibiotics! Right now they are hard at work fighting the nasty Mr. H. Pylori in my stomach. I think the antibiotics are winning! I went many years before this was diagnosed (and only diagnosed when I suggested we test for it). It would not be pleasant living with this the rest of your life.
I think H.Pylori was responsible for many cases of ‘ulcers’ for a long time before they realized it was involved.
