I was diagnosed with iron deficiency anaemia in the summer. My haemoglobin is back to normal but my iron is still borderline low, although much better than it was. While I don't feel as horrific as I did with low haemoglobin, I'm still not feeling well. I am breathless upon exertion and very, very fatigued. I've seen a respiratory specialist who did lung function tests and a CT scan, so we know there's nothing else going on. Is this normal with low iron? My GP was spectacularly unhelpful and I've restored to turning to others for advice. Thanks in advance.
