I'm 61 and living in Australia. I was diagnosed with PA in March 2015 (Chronic atrophic gastritis with no Intrinsic Factor) and am having maintenance B12 injections every 3 months. I am considering self injection because my symptoms return around week 7-8 and I am pretty worn out by week 12. I have not been able to find any information on the foods to avoid for my overall good health and this is the most urgent question I have. GP said no alcohol, carbonated drinks or coffee and prescribed Nexium for reflux which I have never had.I have stopped Nexium as it made me feel sick. When I asked about diet the specialist said,"Go live your life and come back when you have diabetes or thyroid disease." Not a lot of use. Any websites with recommendations?
