I was diagnosed with a stomach ulcer caused by the helicobacter pylori infection in 2009 and, after the infection cleared, was prescribed a proton pump inhibitor which I have been taking ever since with increased dosage. In June 2010 I had a heart attack and in September 2010 was diagnosed with B12 deficiency. I have 3 monthly injections which are generally effective until the last couple of weeks. However, I still have awful gastritis - gnawing pain in my stomach and a hard, bloated abdomen. I used to think this was a symptom of B12 deficiency, but have now read that it is more likely to be a cause. Also that PPIs are a contributory factor, but if I try to wean myself off them my stomach symptoms get worse, especially as I am taking aspirin for my heart. All these symptoms/diseases/drugs seem to be connected and I feel that I am in a cycle that is spinning out of control. Anyone else got experience of anything like this?
