A person with anemia will feel tired and weak. That's because the body's tissues are not getting enough oxygen. In fact, fatigue is the main symptom. The severity of symptoms is in part related to how severe the anemia is. Mild cases can occur without symptoms and may be detected only during a medical exam that includes a blood test.
Symptoms of anemia include:
Heart palpitations (rapid or irregular beating)
Ringing in the ears (tinnitus)
Common signs include:
The normally red lining of the mouth and eyelids fades in color
Rapid heartbeat (tachycardia)
Abnormal menstruation (either absence of periods or increased bleeding)
Other signs depend on the cause. These can include spoon-shaped finger nails and toenails in iron-deficiency anemia, mild jaundice in hemolytic anemias, and leg ulcers in sickle cell anemia .
