Anaemia Due to Iron Deficiency
Anaemia caused by the deficiency of iron is:
- Normocytic and Normochromic
- Microcytic and Hypochromic — Correct Answer
- Macrocytic and Hyperchromic
- Aplastic anaemia
Explanation:
Correct Answer: Microcytic and Hypochromic
Iron deficiency anaemia produces Microcytic (small RBCs) and Hypochromic (pale/less hemoglobin in RBCs) anaemia because iron is essential for hemoglobin synthesis.
Classification of Anaemia by RBC Morphology
| Type | Deficiency | Example |
|---|---|---|
| Microcytic & Hypochromic | Iron (Fe) | Iron deficiency anaemia |
| Macrocytic & Hyperchromic | Vitamin B₁₂, Folic acid, Cobalt | Pernicious anaemia, Megaloblastic anaemia |
| Normocytic & Normochromic | Chronic disease (no specific nutrient) | Anaemia of chronic disease |
| Aplastic anaemia | Failure/destruction of bone marrow | Radiation, drugs |
Note on Cobalt
Cobalt deficiency leads to Vitamin B₁₂ deficiency (cobalt is a component of B₁₂/cobalamin), resulting in macrocytic hyperchromic anaemia. In ruminants, cobalt deficiency is common on cobalt-deficient soils.
