Heart palpitations

A fast heartbeat that you may feel in your chest, throat, or neck is the most common symptom of heart palpitations. It may feel like your heart is stopping, pounding, or flip-flopping at times.

Heart palpitations, or noticeable heartbeats, are another symptom of iron deficiency anemia. The link between iron deficiency, anemia, and heart disease is still being studied, although it might be linked to oxygen supply. Hemoglobin is a protein found in red blood cells that helps in the transport of oxygen throughout the body. Low hemoglobin levels in iron deficiency mean the heart needs to work extra hard to transport oxygen. This might cause irregular heartbeats or the feeling that your heart is beating too quickly. As a result, iron deficiency can exacerbate heart conditions such as heart failure and coronary heart disease.
