Hi Its Been 4 Months Now That I Taking 40mg

Hi its been 4 months now that I taking 40mg omeprazoles, sometimes taking also a gaviscon for my stomuch if my stomuch pain is not manageable and OSOSAN to dissolve my gallstones but still I have feeling uncomportable in my stomach. Sometimes go and come back again in few days. I have checked my boold count FBC, SE E/LFT, SE CRP all normal but my ALT is 69 the normal range (0-45) and my lipase too is slightly elevated which is 260 the normal is 60-250. Can you please tell me what is this cause? Right now I am feeling uncomportable again with my stomach.
Thanks,
Emmanuel
