O no! What did I not eat?!

So I did a blood test or should I say a bunch of blood tests (that left me with a nasty bruise) and I got my results today. I am clear on the HIV front but apparently, I have anaemia and not the 'you don't have enough iron type' this one I had never heard of till today. Normochromic Normocytic Anaemia, yup quite a mouthful! Not sure what that is, have done a little research online but still not quite clear...
