Complications
If not treated, anemia can cause many health problems, such as:
Severe tiredness. Severe anemia can make it impossible to do everyday tasks.
Pregnancy complications. Pregnant people with folate deficiency anemia may be more likely to have complications, such as premature birth.
Heart problems. Anemia can lead to a rapid or irregular heartbeat, called arrhythmia. With anemia, the heart must pump more blood to make up for too little oxygen in the blood. This can lead to an enlarged heart or heart failure.
Death. Some inherited anemias, such as sickle cell anemia, can lead to life-threatening complications. Losing a lot of blood quickly causes severe anemia and can be fatal.
