Sickle Cell Anemia: Symptoms & Signs

Medically Reviewed on 8/18/2020

Sickle cell anemia is a genetic (inherited) blood disease that results in the production of an abnormal form of hemoglobin. The abnormal hemoglobin causes the red blood cells to form an abnormal (sickled) shape under conditions of low oxygen. These red blood cells die off more easily than normal red cells, causing anemia (too few red blood cells), and they form clots in small blood vessels, preventing blood supply from effectively reaching body tissues.

Signs and symptoms of sickle cell anemia include

  • pain crises (sickle cell crisis),
  • joint pain,
  • chest pain,
  • dizziness,
  • fatigue,
  • malaise,
  • delayed development,
  • frequent infections,
  • swelling of the feet or hands,
  • pallor,
  • shortness of breath, or
  • yellow skin and eyes (jaundice).

Cause of sickle cell anemia

A genetic mutation causes sickle cell anemia. Children who inherit two copies of the sickle gene, one from each parent, have sickle cell anemia.
