5 basic causes of anemia
Anemia caused by insufficiency of iron for hemoglobin formation, and blood corpora have become pale and small, this type of anemia said to be hypochromic and microcystic anemia.
The deficiency of vitamin B12 and folic acid leads to impairments in their utilization and causes damaged DNA. Lack of these vitamins in the cells which they are entered in the bloodstream has become irregular in size and shape, but usually larger than normal this type of anemia knows as megaloblastic anemia.
If either iron or folate and vitamin B12 are deficient it gives rise to hypochromic macrocytic or dimorphic anemia.
