Complications

By Mayo Clinic staff

Left untreated, anemia can cause numerous complications, such as:

  • Severe fatigue. When anemia is severe enough, you may be so tired that you can't complete everyday tasks. You may be too exhausted to work or play.
  • Heart problems. Anemia can lead to a rapid or irregular heartbeat — an arrhythmia. Your heart must pump more blood to compensate for the lack of oxygen in the blood when you're anemic. This can even lead to congestive heart failure.
  • Death. Some inherited anemias, such as sickle cell anemia, can be serious and lead to life-threatening complications. Losing a lot of blood quickly results in acute, severe anemia and can be fatal.
