Anemia can be described as a disease in which the red blood cell count or hemoglobin is decreased. Besides the decrease in red blood cell count or hemoglobin the shape of red blood cells (that is poor or malformed cells) also affects oxygen delivery to the tissues.
The normal level of hemoglobin depends on the age and sex of the person. Like in men hemoglobin level of less than 13.5 gram/100ml and in women hemoglobin level of less than 12.0 gram/100ml is considered to be a sign of anemia. Hemoglobin is the substance present in red blood cells which helps to transport oxygen to all the organs and cells in the body and removes harmful gasses (that is carbon dioxide). And its absence causes anemia.
There are several different types of anemia. Some of the common and well known anemia are iron deficiency anemia, vitamin B-12 anemia (pernicious anemia), thalassemia and sickle cell anemia.Whatever is the cause and type of anemia the entire body suffers. Consult your doctor if you or any of your family members appear pale (a common symptom of anemia).
