Part 5 of our Understanding Your Labs series.
Iron Deficiency Anemia
If iron is the cause, iron replacement is started right away.
- Oral iron — most commonly ferrous sulfate — is the standard first-line treatment. It is inexpensive and effective, but it takes time and can cause GI side effects.
- IV iron infusions are used when oral iron is not tolerated, when the deficiency is severe, when GI absorption is impaired (for example after bariatric surgery), or when surgery cannot be delayed long enough for oral iron to work. IV iron corrects levels far faster.
The choice between oral and IV iron is a clinical decision made with your primary care physician or hematologist based on your timeline, severity, and tolerance.
B12 or Folate Deficiency
If MCV is elevated, the underlying vitamin deficiency is replaced directly.
- Methylcobalamin (vitamin B12) — either oral, sublingual, or injection depending on severity and cause.
- Methylfolate — oral supplementation.
Underlying causes matter here too. Pernicious anemia, poor absorption after gastric surgery, and dietary deficiencies each have different long-term management plans.
When Surgery Gets Delayed
Sometimes the right call is to delay surgery. That is frustrating — travel is booked, work is off, family is coming in — but a good surgeon knows the difference between a scheduling problem and a safety problem.
Optimizing your blood work first is not slowing you down. It is protecting the outcome you paid for. Rushing through poor labs raises the risk of complications, prolongs recovery, and can compromise the final result.
Key Takeaway
Fixing anemia before surgery is not optional — it is how you get the safest procedure and the best possible recovery. The exact treatment depends on the cause, but the principle is the same: optimize first, operate second.
