What is megaloblastic anaemia?
Here, the red blood cells (RBC) count is low and the RBCs are larger in size. This is a
macrocytic anaemia, and is commonly due to vitamin B12 and folic acid deficiency.
Pernicious anaemia is a variety of megaloblastic anaemia where there is atrophy of
gastric mucosa which leads to loss of parietal cells and thereby leading to deficiency
of intrinsic factor resulting into disturbance in absorption of vitamin B12.
Remember, iron deficiency anaemia is a microcytic anaemia.
