In general, most of the megaloblastic anaemia that occurs in our country is nutritional in nature, that is, it is caused by a deficiency of folic acid, vitamin B12 or both in the diet, and all recover more quickly when the deficiency is replenished.
Other cases of megaloblastic anaemia due to absorption disorders, drug interferences, etc. also have a good outcome when the cause is removed and treated with supplements.
In megaloblastic anaemia with a corresponding primary cause, the focus is on whether the primary cause can be effectively eradicated.
