Hi folks. I live in Australia and I used to be on the old forum which I found most helpful as was the entire web site. My B12 deficiency has been kept in check with monthly injections, though some doctors are reluctant to administer them this frequently. I have recently been diagnosed with some stomach inflammation and told the treatment is proton pump inhibitors. I am interested to hear how others manage with this kind of medications and if they have experienced worse b12 deficiency.
