What do you suggest if my doctor gave me treatment for h pylory clarithromycin ,metronidazole,omeprazol is it correct?

Treat the H.pylori: H.Pylori status is checked with the intention of treating the infection to eradication, when found. There are a lot of multi-drug regimens of variable durations that have efficacy against this organism. None are perfect., including the one you mentioned. If that is however what your doctor recommends, then take it as prescribed and to completion please.
