Anemia

Definition: Anemia is a haematological disorder that results in reduced capacity to carry oxygen in red blood cells due to a lack in hemoglobin, a lesser amount of hemoglobin per red blood cell or is caused by an overall lack/ dysfunction of red blood cells. Anemia can have different causes and is associated with a range of medical diseases and conditions. A common cause for anemia is a reduced capacity to synthesize sufficient hemoglobin as the oxygen carrying protein, e.g. resulting from a lack of iron, vitamins or malnutrition, or a substantial loss of blood due to major injury.

Alternative definition: (if applicable) Anemia is a condition in which normal hemoglobin content in the blood is reduced, resulting in insufficient oxygen supply to the body. This is mainly caused by iron deficiency and blood loss.
