Anemia is a condition in which the red
blood cell (RBC) count or hemoglobin is less than normal.
RBCs in the blood have a very crucial role to play as
they contain hemoglobin, which carries oxygen to the body tissues. Anemia leads
to a host of health complications as body tissues are deprived of the required
amount of oxygen to keep them healthy. Thus, victims of anemia often complain
of extreme fatigue.
General malaise, weakness, fatigue, breathlessness on exertion, palpitations,
and angina are some of the symptoms of anemia.
Anemia can be caused due to nutritional deficiencies, especially iron and
vitamin deficiency. Inherited disorders also cause anemia. Exposure to a
particular drug or toxin, and certain kinds of cancer also cause anemia. Anemia
can set in either due to abnormal loss of blood, or insufficient production of
RBCs or when RBCs are destroyed due to an existing medical condition.
Anemia is diagnosed after conducting a complete blood cell (CBC) count, which
examines the different types of cells in the blood.
Treatment for anemia is targeted towards the cause of the condition and its
outcome depends upon the cause, extent of the condition and general health of
the patient. Generally, the prognosis is good for victims of anemia.
