Nutritional deficiency anemia

# Which of the following is nutritional deficiency anemia?
A. Aplastic anemia
B. Sickle cell anemia
C. Spherocytosis
D. Megaloblastic anemia


The correct answer is D. Megaloblastic anemia.

Iron deficiency and megaloblastic anemia are called as nutritional deficiency anemias.

Iron deficiency anemia is most common in hookworm infestations in children.
Megaloblastic anemias are due to impaired DNA synthesis and are characterized by delay in the maturation of nucleus. Cells primarily affected are those having relatively rapid turnover, especially hematopoietic precursors and gastrointestinal epithelial cells. 

The underlying defect for maturation arrest is due to deficiency of Vitamin B12 and/or folic acid.
