Hey all, I was diagnosed with PA over a year ago due to a general check-up and got a full blood count done. My b12 levels were seriously low and iron too.I never really had any symptoms or felt overly tired it was quiet a shock for me. My doctor then referred me on to a GI specialist who recommended a endoscopy. My results found I had widespread non-erosive gastritis and also they found a small lesion in my stomach that was atrophic gastritis and did several biopsies. Everything came back normal with some inflammation there too. I have to go back now soon for a follow up endoscopy and colonoscopy as colon cancer ruins in my family. Its scary how you can have all this going on and only for my doctor recommended an endoscopy I would of never known. Does anyone else have autoimmune gastritis due to b12?
