What is anemia?
Anemia is a condition in which the body does not have enough healthy red blood cells to carry oxygen to the body's tissues. Anemia can cause fatigue, shortness of breath, dizziness and other symptoms.
How Does a Blood Transfusion Help Anemia?
A blood transfusion is a common treatment for anemia, as it can increase the amount of healthy red blood cells in the body. During a blood transfusion, a person receives healthy red blood cells, either from a donor or from their own body. Blood transfusions can provide a person with the oxygen-carrying capacity needed to relieve symptoms of anemia.
How Long Does a Blood Transfusion Help Anemia?
The effects of a blood transfusion can last for several weeks or months, depending on the type and severity of anemia. In some cases, a person may need to have recurrent transfusions to maintain their red blood cell levels. However, the effects of a blood transfusion are usually temporary and anemia may return if the underlying cause is not addressed.
