The Claim

Long-term regular blood transfusions for sickle cell disease can cause iron overload.

Verified by Lenz ·

The Short Version

Long-term regular transfusions in sickle cell disease are a well-established cause of transfusional iron overload. Multiple authoritative reviews and clinical studies show that repeated transfusions add iron faster than the body can remove it, causing iron accumulation over time. The risk may be lower with some exchange-based regimens, but the claim itself is accurate.

Caveats

  • Risk is not identical across transfusion methods; automated red-cell exchange can reduce iron loading compared with simple transfusion.
  • The claim says “can cause,” not that iron overload happens in every patient or every regimen.
  • Clinical impact depends on monitoring and management, including ferritin/liver iron assessment and iron-chelation therapy when indicated.
