Overview
Vegan anemia, often iron-deficiency anemia due to limited dietary iron sources, can affect individuals adhering strictly to a vegan diet without proper supplementation or fortified foods 3.Diagnosis
Key Diagnostic Criteria: Low hemoglobin (Hb) levels, decreased packed cell volume (PCV), and reduced total erythrocyte count (TEC) 1.
Recommended Tests: Complete blood count (CBC) including Hb, PCV, and TEC; serum ferritin levels to assess iron stores 3.
Grading: Mild anemia indicated by Hb 10-12 g/dL, moderate 7-10 g/dL, severe <7 g/dL 3.Management
First-Line Treatments: Iron supplementation, preferably ferrous sulfate or ferrous gluconate, aiming for 100-200 mg elemental iron daily 3.
Adjunctive Treatments: Dietary modifications to include iron-rich plant sources (e.g., lentils, spinach) and vitamin C to enhance iron absorption 3.
Monitoring: Regular follow-up CBCs and ferritin levels to assess response to treatment 3.Special Populations
Pregnancy: Increased iron requirements necessitate higher iron supplementation doses, typically 60-90 mg elemental iron daily 3.
Pediatrics: Close monitoring and tailored supplementation based on growth charts and developmental stages 3.
Elderly: Consider potential interactions with other medications and ensure adequate absorption with vitamin C-rich foods 3.
Comorbidities: Individuals with chronic diseases may require individualized treatment plans, possibly involving higher iron doses or intravenous iron therapy 3.Key Recommendations
Screen vegans for anemia with CBC and serum ferritin levels to identify iron deficiency early (Evidence: Moderate 3).
Recommend iron supplementation tailored to individual needs, especially during pregnancy and in pediatric populations (Evidence: Moderate 3).
Encourage dietary modifications to include iron-rich plant foods and vitamin C to enhance iron absorption (Evidence: Expert opinion 3).References
