Causes of Anemia | What Causes Iron Deficiency Anemia

Anemia Causes

Anemia is caused by a few things, but two of the main avenues of the development of anemia stems from either the decrease of the hemoglobin or red blood cell production of the body or by a person losing a lot of blood due to an injury or because of the destruction of this blood due to an illness.

Here are other causes that can be cited for why a person may have anemia:

  • One of the major reasons why a person may have anemia is the low intake of iron in the diet or in the system in general. Iron deficiency can indeed cause anemia and is actually one of the most common causes of this problem.
  • Acute anemia is caused by bleeding or hemorrhaging due to an internal or external injury. This is due to the excessive loss of blood brought about by this event. This is usually an anemia that occurs after a person has an accident or a traumatic physical injury.
  • Pernicious anemia can be caused by a deficiency in vitamin B12.
    This is usually an anemia that afflicts severe vegetarians and long-term alcoholics. This inability to absorb vitamin B12 into the system from natural sources and from supplements usually is because of these problems.

Sickle Cell Anemia Causes

Main cause of anemia of this kind is inheritance. Sickle cell gene is inherited from each parent. This gene causes inadequate hemoglobin production by the body.

Aplastic Anemia Causes

Aplastic anemia is due to the bone marrow injury which slows down or stops producing red blood cells. Damage to the bone marrow can be due to intake of certain drugs, autoimmune disorders like lupus, chemotherapy or infectious viruses like Epstein-Barr, HIV.

Pernicious Anemia Causes

This type of anemia causes due to the presence of wrong bacteria in the intestine, abnormal absorption of Vitamin B12 by the intestine, due to the intake of medicines which changes the growth of bacteria.
