Anemia, Iron, and B12 Before Pregnancy

Review anemia history, iron and B12 labs, heavy periods, diet pattern, supplements, and treatment questions before pregnancy. It is designed as preparation for a preconception visit, not a personal treatment plan.

Educational boundary: this guide is general health information. It does not diagnose, treat, adjust medicine, or replace care from a qualified clinician.

Bring lab history

List prior hemoglobin, ferritin, iron studies, B12, folate, and any treatment side effects.

Name possible causes

Mention heavy periods, GI symptoms, vegetarian or vegan diet, bariatric surgery, bleeding history, or medicines that affect absorption.

Plan monitoring

Ask when to repeat labs, what dose is appropriate, and what symptoms should prompt earlier care.

Questions to bring

  • What is the safest next step before trying to conceive?
  • Which medicines, labs, symptoms, or records should be reviewed first?
  • What should I do if pregnancy happens before the plan is finished?
  • Should another clinician, pharmacist, counselor, or specialist be involved?
