What you need to know — and what we can do together
Understanding the Basics
Carry oxygen from your lungs to your body and baby
Too few red blood cells, or too little hemoglobin to carry enough oxygen
Diagnosed when hemoglobin < 11.0 g/dL
A routine blood test at your prenatal visit

Anemia is very common in pregnancy — and very treatable.
Pathophysiology

~40% of cases
Megaloblastic anemia
Prevented by prenatal vitamins
Sickle cell disease
Thalassemia syndromes
Recognizing Anemia
Many women have no symptoms at all — which is why routine screening matters.
Clinical Significance
For Mother
For Baby
✓ With early treatment, most of these risks can be significantly reduced.
Monitoring
Ferritin < 30 µg/L indicates depleted iron stores — even before hemoglobin falls.

What to Expect
Treatment Comparison
| 💊 Oral Iron | 💉 IV Iron | |
|---|---|---|
| Best For | Mild to moderate anemia | Severe anemia or oral intolerance |
| Dose | 60–120 mg elemental iron/day | Calculated by your doctor (Ganzoni formula) |
| Side Effects | Nausea, constipation, dark stools | Minimal; infusion site reactions (rare) |
| Speed | Gradual (weeks) | Faster correction |
| Timing | Any trimester through postpartum | Preferred after 32 weeks |
Other Types of Anemia
Essential for red cell production and baby's neural tube development.
Needed for healthy red blood cells. More common in vegetarian/vegan diets or after weight-loss surgery.
Nutritional Support
Heme Iron (Best Absorbed)
From animal sources — absorbed 2–3× more efficiently
Non-Heme Iron
From plant sources — pair with vitamin C to boost absorption
Diet alone cannot fully meet pregnancy's iron demands — supplements remain essential.

Prevention
Every day — it contains iron, folate, and B₁₂
Include iron-rich, folate-rich, and B₁₂-rich foods
Routine screening catches anemia early
Tell your doctor about any dietary restrictions, surgeries, or conditions that may affect absorption.
Anemia is common, detectable, and treatable.
Most women see improvement within a few weeks of starting treatment.
Regular monitoring
Consistent treatment
Healthy outcomes
Always follow your doctor's recommendations about supplements and follow-up testing.
