Anemia is a condition that occurs when there is a significant drop in red blood cells (erythrocytes), and/or their main building blocks – hemoglobin, in the blood. Hemoglobin binds oxygen to itself and its role is to transport this oxygen through the bloodstream to all tissues and organs in the body so that they can function normally.
Therefore, if there is a drop in red blood cells or hemoglobin below normal values, the tissues and organs will not be nourished, and various symptoms will begin to appear.
Why does anemia occur?
There are several types of anemia, as well as many different causes and methods of treatment. Some are mild, transitory, and are not a sign of concern, while some others represent more serious, chronic disorders. Anemia can also be an indicator of some other diseases that cause it.
