Vitamin B12 Deficiency
Nutritional focus for megaloblastic anemia, often seen in vegans or patients with absorption issues (Pernicious anemia).
Dietary Sources
- Animal products: meat, fish, eggs, and dairy.
- Fortified nutritional yeast or breakfast cereals.
- Advise vegans to take supplements or consume fortified foods.
Clinical Considerations
- Pernicious anemia requires lifelong B12 injections as it lacks intrinsic factor.
- Monitor for neurological symptoms (numbness, tingling, ataxia).
- Assess for glossitis (smooth, beefy-red tongue).
