How common is dizziness in iron deficiency anaemia?

Iron is needed to make haemoglobin, the part of red blood cells that carries oxygen. When iron deficiency leads to anaemia, you may feel tired, weak, breathless with activity, lightheaded, headachy, or notice a fast heartbeat. Symptoms can build gradually, so they may be easy to attribute to stress or lack of sleep.

Dizziness has many possible causes, and it does not by itself establish Iron Deficiency Anaemia. Heavy menstrual bleeding, pregnancy, low iron intake, poor absorption, or bleeding in the digestive tract can contribute. Blood tests help confirm anaemia and iron status, while further assessment looks for the reason.

Arrange an appointment if dizziness is recurrent or accompanied by ongoing tiredness, pale skin, breathlessness, headaches, or a racing heartbeat. A clinician may ask about menstrual bleeding, diet, digestive symptoms, previous conditions, and medicines before deciding which tests are appropriate.

Do not start high-dose iron without medical advice. Iron supplements are not suitable for every cause of anaemia and can cause side effects. Follow the prescribed plan and attend follow-up testing so treatment and the underlying cause can be checked.

Seek urgent help for fainting, chest pain, severe breathlessness at rest, confusion, a very fast or irregular heartbeat, or sudden heavy bleeding. Dizziness with black stools, vomiting blood, or marked weakness also needs prompt assessment.

Contact a clinician soon if symptoms are worsening, affect walking or work, or persist despite rest. Sudden dizziness with facial drooping, one-sided weakness, trouble speaking, or new vision loss is an emergency.

Could iron deficiency explain my symptoms, and which blood tests are appropriate? What might be causing low iron? Should I change my diet or take a supplement, and how will we check whether treatment is working?
