Does anaemia cause palpitations?

Palpitations can feel like pounding, fluttering, racing, or skipped beats. With anaemia, reduced oxygen-carrying capacity can prompt the heart to work harder, particularly during activity. You may notice the sensation alongside tiredness, dizziness, headaches, or breathlessness.

Palpitations also have many other possible causes, such as stress, fever, dehydration, caffeine, thyroid problems, medicines, or a heart-rhythm condition. A clinician may check your pulse, blood pressure, heart rhythm, and blood tests rather than assuming anaemia is responsible.

Arrange an assessment if palpitations are new, recurring, or interfering with normal activity. Record when they happen, how long they last, whether the rhythm feels regular, and what you were doing beforehand. Mention caffeine, supplements, medicines, heavy periods, bleeding, or recent illness. Avoid taking iron unless a clinician has identified a reason for it.

Get urgent medical help if palpitations continue with chest pain, severe breathlessness, fainting, collapse, confusion, or marked weakness. Seek prompt advice for a very fast or irregular heartbeat that does not settle, especially if you have known heart disease or significant bleeding.

Ask whether a full blood count and iron-related tests are suitable, whether an ECG is needed, and what might be triggering the episodes. Clarify which pattern of palpitations is concerning and what to do if symptoms return before your results are reviewed.
