glossary:anemia

(1) The condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased.

Persons with anemia may feel tired and fatigue easily, appear pale, develop palpitations and become unusually short of breath (Dyspnea). Children with chronic anemia are prone to infections and learning problems.

Anemia has four basic causes. One or more of these causes must be operating to produce anemia:

Hemorrhage – bleeding Hemolysis – excessive destruction of red blood cells Underproduction of red blood cells Not enough normal hemoglobin

(2) Below normal levels of red blood cells or hemoglobin, or both, which can be caused by many different conditions, including iron deficiency. Symptoms may include fatigue, weakness, headache, and dizziness. Appropriate blood tests will confirm the diagnosis of anemia and shed light on its etiology.
