Symptoms

Signs and tests

The doctor will perform a physical examination. Anemia can be confirmed by a red blood count or hemoglobin level.

Treatment

This type of anemia responds to treatment of the disease causing anemia. It is rarely severe enough to require blood transfusion.

Complications

Discomfort from symptoms is the primary complication of most cases.
