Can iron deficiency cause tremors and fatigue?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

I am just wondering if it is possible to have neurological symptoms with low ferritin levels. My hemoglobin is 13, but the last check on ferritin said it was 5.3. I am suffering severe internal tremors, fatigue, cold hands and feet and weak, shaking legs. My symptoms improve while on a short course of iron, but the minute my period arrives, I am a mess again with my symptoms back to square one. Any advice would be appreciated.

Kindly help.

Hello,

Welcome to icliniq.com.

  • Low ferritin levels can cause fatigue and weakness.
  • A full iron deficiency panel needs to be done. This includes:
  1. CBC (complete blood count)
  2. Differentials.
  3. Hemoglobin.
  4. RBC (red blood cell).
  5. Hematocrit.
  6. RDW-CV.
  7. MCV.
  8. MCH.
  9. Serum iron.
  10. TIBC (total iron binding capacity).
  11. Saturation rate.
  12. Ferritin.

I would advise you to continue taking iron tablets till your ferritin levels are at least 65. You could try taking iron tablets with lemon juice in water, as this can increase absorption.

I hope this helps.
