if i was suffering from sort of normal iron deficiency - which is what it looks like, granted - then i should also be generating small blood cells. but, i'm not - my blood cells are unusually large and it seems like they get bigger and bigger as i eat less and less.
this combination - low ferritin and large rbcs - is weird.
now, i only have three data points and they're bunched up in time. but, it seems like the size of my red blood cells increases as i eat less, and decreases as i eat more. so, is it possible that my iron is low because i'm producing extra large rbcs, which kicks in when i don't eat enough?
whatever it is is weird, but that's just pointing more and more towards the marrow.
