It's really common for us to have anemia of chronic disease due to chronic inflammation, but it's important to have your doctor check to see if you may have iron deficiency. Sometimes, vitamin B12 or folate deficiency can also cause anemia with larger than usual red blood cells, which your doctor can tell from your labs. We women who are still menstruating often get iron deficiency if we have heavy periods.
Take care!

There are different kinds of anemia. I have iron deficiency without anemia, anemia of inflammation. My iron levels look fine but ferritin should usually be about 100 in someone with chronic inflammatory conditions. Mine was 23, Don never offered me treatment. I finally have it up to mid fifties.
You may have another kind of anemia.

Only that when I developed anemia my rheumatologist suspected the medication I was on first and decreased it. I am on Imuran and Prednisone.
