Answer:
Anemia is a very common, but also partially neglected disease. It is characterized by low levels of hemoglobin in the blood or decreased levels of erythrocytes. Since erythrocytes carry oxygen to all organs, it is clear that their deficiency seriously endangers the work of the whole organism.

Anemia can occur if the body produces too few blood cells or if the blood cells do not function properly.
Some types of anemia are:
Megaloblastic anemia
Congenital dyseritropoiesis.
Hemolytic anemia
