I am a 28-year-old female with recurrent iron-deficiency anemia for several years. My recent blood tests (18 Aug 2026) show Hb 9.4 g/dL, MCV 65.84 fL, serum iron 15.8 µg/dL, transferrin saturation 3.94%, RDW 17.1%,
Ferritin- 7.8,
vitamin D 6.01 ng/mL,
B12 182 pg/mL,
calcium 8.37 mg/dL and ESR 32.
I have heavy menstrual bleeding and have required several iron infusions in the past, but the anemia keeps recurring. I currently have significant fatigue, hair fall, irritability and mood changes. Also, gut issues.
My questions:
1. What could be causing my recurrent anemia despite IV iron?
2. What tests should I have to investigate heavy menstrual bleeding, iron malabsorption/coeliac disease, or other causes of recurrent iron deficiency?
3. Should I see a gynecologist, hematologist, or gastroenterologist?
4. What treatment would you recommend for my iron deficiency, severe vitamin D deficiency and low B12?
5. How can I prevent the anemia from recurring?
