What causes anemia?

It includes any process which can interrupt the normal life span of red blood cells.120 days is the normal life of red blood cells and are made in bone marrow.

Anemia is caused through two pathways.

  • Decrease in the number and production of red blood cells
  • Loss of blood

Absence of enough iron in food and diet supplements can cause anemia as iron is the major component of hemoglobin. Accidental loss of iron will result in the low level of hemoglobin in the body which later on cause anemia. Such anemia which is caused due to low iron levels in the body is called iron deficiency anemia as iron deficiency is the major cause of anemia.

Women are more likely to have the deficiency of iron than men because every month there is a small and temporary blood loss through normal menstruation. Small and repeated bleeding from stomach ulcers and colon cancer can also cause cancer. Acute blood loss either through internal bleeding like ulcer bleeding or internal bleeding as from trauma can produce anemia. If the symptoms are not addressed properly; this type of anemia could result in severe consequences.

Pernicious anemia is caused by the deficiency of vitamin B12 and develops in people who are unable to absorb vitamin B12 due to many reasons which include:

  • Vegetarians who do not take vitamin supplements with diet
  • Long-term use of alcohol

Not only vitamin B12 but also folate is involved in making heme molecule. This can also be caused by improper absorbtion, long-term use of alcohol and under-consumption of green vegetables.

Anemia is also caused by a wide assortment of diseases related to bone marrow. For example, leukemia, multiple myeloma, chemotherapy for cancer treatment, kidney failure, AIDS and anemia of chronic disease.
