Can Low Iron Cause Heart Palpitations?

Yes, low iron (iron deficiency anemia) can cause heart palpitations. When iron levels drop, your body produces fewer red blood cells, reducing oxygen transport throughout your body. To compensate for this decreased oxygen delivery, your heart works harder and beats faster, often creating the sensation of palpitations or irregular heartbeats. Studies show that up to 69% of people with iron deficiency anemia experience cardiac symptoms including palpitations. Other symptoms typically accompany palpitations, such as fatigue, shortness of breath, and weakness. If you're experiencing persistent palpitations along with these symptoms, blood tests measuring ferritin, iron, and complete blood count can help determine if iron deficiency is the underlying cause.
