I have Lupus and my recent blood tests show anaemia with a very low ferritin level. My GP is blaming heavy periods but I am not convinced as they have been heavier in the past and my bloods were ok then.I am due to have folate, ferratin and B12 levels checked next week and I am wondering if it is more a problem with iron absorption. Thing is I can't tolerate oral iron supplements as they wreck my digestive system. I have tried changing my diet but there is only so much liver you can eat! Any ideas/advice? Is PA associated with auto-immune diseases?
