Megaloblastic anemia is a type of macrocytic anemia. An anemia is a red blood cell defect that can lead to an undersupply of oxygen. Megaloblastic anemia results from inhibition of DNA synthesis during red blood cell production. When DNA synthesis is impaired, the cell cycle cannot progress from the G2 growth stage to the mitosis (M) stage. This leads to continuing cell growth without division, which presents as macrocytosis. Megaloblastic anemia has a rather slow onset, especi… Webwith a non-regenerative macrocytic anaemia (haemoglobin concentration 69 g/l; mean corpuscular volume 95 fl; reticu-locytes 53 9 109/l), neutropenia (0 6 9 109/l) and mild thrombocytopenia (137 9 109/l).

WebIn megaloblastic anemia, cells have a hard time making DNA (because there’s a lack of B12 and/or folate) – but RNA production proceeds normally. So you end up with cells that have normally maturing cytoplasm, but slowly-maturing nuclei. This means that the cell grows pretty large before the nucleus gets mature enough to signal division (so ...
