types of Anemia

Types of Anemia

  • Iron deficiency anemia

Iron deficiency Anemia is caused because of low levels of iron in the blood. It is the most common form of Anemia. The body needs iron for making hemoglobin and as hemoglobin helps in transport of oxygen, with low iron levels body can’t get the amount of oxygen it needs.

Lack of iron in blood may be due to blood loss because of long menstrual periods, ulcers, infections, severe injuries, poor diet or certain intestinal problems that affects the ability of body to absorb iron can also lead to iron deficiency anemia.

  • Vitamin deficiency anemia (megaloblastic anemia)

Our body requires vitamin B12 and folate for production of enough red blood cells. The deficiency of vitamin B12 causes “pernicious anemia”, usually this deficiency may be result of lack of vitamin B12 in the diet or if body is not able absorb vitamin B12 properly due to intestinal problems.

Anemia caused due to deficiency of folate (also known as folic acid) is known as folate deficiency anemia. These types of anemia caused due to vitamin deficiency is known as Megaloblastic anemia

  • Aplastic anemia

Aplastic anemia is a type of anemia in which the production of all types of blood cells (including red blood cells, white blood cells, and platelets) in the bone marrow decreases. It is a rare form of anemia and the cause is uncertain, it may be due to an autoimmune disorder, cancer treatments, exposure to toxic chemicals or a viral infection or may also be inherited.

  • Sickle cell anemia

Sickle cell anemia is a genetic disorder (i.e. it runs in the family) and is caused due to a problem with hemoglobin that causes red blood cells to have an abnormal crescent shape. The body destroys these cells quickly, but the new red blood cells cannot be made fast enough

  • Hemolytic anemia

Hemolytic anemia is caused because of premature death of red blood cells which may be due to the red blood cells themselves (inherited) or because of outside factors. In hemolytic anemia the red blood cells are destroyed faster than the bone marrow can produce new ones. The causes may include blood diseases, autoimmune disorders, and certain medications.
