Hi there, I've just finished my second dose of antibs for h.pylori as the first lot (taken in April) had little effect. The first lot I had in Italy and the doc only gave me 10 days worth of omeprazole to take in conjunction with the antibs..
When I saw my GP in the UK he said, as pps have said, that the omeprazole needs to be taken for much longer usually to get rid of the acid caused by the infection. I had the second dose of antibs and am currently on my second month of omeprazole...I still get days when I have twinges, but I'm pretty sure the actual infection, this time is gone. I'm now only taking the omeprazole every few days.
The GP told me that in the UK the tendency is to treat h.pylori twice only, then if it still persists to keep it under control with omeprazole etc. The antibodies in the blood can last for up to 6mths my doc said, (not forever) which is why the second test is usually the urea breath test or a stool test. (when my stepfather had it, his was diagnosed with a stool test) Here in Italy the doc wanted to send me straightaway for biopsies and feck knows what else, and tbh had me really freaking out it was Something Very Bad, but the UK GP was really relaxed about it which I think also helped me psychologically, to get rid of it, and not have twinges which might well have been stress related from the Italian doc scaring me!
Ask for a stool test (the h.pylori foundation website explains all of these tests) in fact, I believe IIRC, my stepfather's second test he did himself, asking the pharmacist for the kit and then sending it off to a lab in Yorkshire.
These are such simple tests I don't see why your GP is being so arsey about doing them.
Hope you get some joy.
I also find taking Holland and Barret extra strength peppermint oil capsules calm my stomach down (especially after a heavy meal) and I have a tub of gastrocote as well, which are better than most over-counter stuff.
