hi, I have perniciuos anemia and cause IF lack. I had hpylori about 20 years had 3 treatments just a bit of history there but have been cured of that issue. i also had severe vit D deficiency discovered at same time last october of pernicious anemia. I get B12 injetions every three weeks or i start having symptoms nerve wise. My question is. Can I heal the stomach IF issue? I was not a drinker of achohol most my life until about 40 I am 50 now and enjoy wine nightly at dinner. Is it harmful to drink to my stomach or is that damage already done?
