Sports Anaemia

My experience with developing anaemia through training, both lifting and cardio

2021 was the 3rd time I have become anaemic through iron loss leading to deficiency in red blood cells. I never want to go through this again. If this helps one person, I'll be happy with that.


It is torture - sure, you could do a 9 to 5 office job with low iron, ferritin and screwed up RBCs, but training on top? No chance. So, I'm documenting here for myself what not to do in the future.



Possible causes
  • Hypothyroidism / hypothyroid episodes may deplete iron
  • Celiac disease
  • Foot striking
  • Blood in stools - particularly from powerlifting squats/deads

Possible treatments
  • Iron supplementation OTC — good to maintain levels, takes months to replenish
  • Iron supplementation prescription (Ferrous fumarate) - I have restored iron quickly by megadosing this but do not recommend it
  • Iron infusion — intravenous. Harley street — if your time is valuable.
  • Keep thyroid levels (FT3) within range. Or adjust by TSH.
