Anemia Causes

http://anaemic.org/anemia-causes.php

Anemia is generally caused by blood loss, lack of red blood cell production or high rates of blood cell destruction. Some anemias are caused by more than one of these causes.

Before we talk about anemia causes, let us explain how the circulatory system functions. Red blood cells are oxygen carriers which transport oxygen from the lungs to different parts of the body. A protein called hemoglobin enables these cells to do that and carry carbon dioxide from various parts of the body to the lungs so that they could be exhaled. Red blood cells, as well as other blood cells, are produced in the bone marrow.

The most common anemia cause is blood loss, especially the type called iron-deficiency anemia. It may be caused by very heavy menstrual periods or internal bleeding in the urinary or digestive tract. Other anemia causes may be surgery, trauma or cancer and cancer treatments.

Not having enough blood cells is also one of the anemia causes. This phenomenon may be either acquired or inherited.
