What is iron deficiency?
Iron deficiency is the most common nutritional deficiency worldwide and is particularly prevalent in Australia, affecting an estimated one in five women of reproductive age. Iron is essential for producing haemoglobin, which carries oxygen in the blood. When iron levels are low, your body cannot produce enough healthy red blood cells, potentially leading to iron deficiency anaemia.
Symptoms of iron deficiency may include fatigue, weakness, pale skin, shortness of breath, dizziness, cold hands and feet, brittle nails, and difficulty concentrating. Some people may be iron deficient without obvious symptoms, which is why blood testing is important if iron deficiency is suspected.
When to see a doctor about iron deficiency
You should see a GP if you are experiencing persistent fatigue, unusual shortness of breath, dizziness, or other symptoms that may suggest iron deficiency. It is also important to see a doctor if you have heavy menstrual periods, are pregnant or planning pregnancy, follow a vegetarian or vegan diet, or have a condition that may affect iron absorption.
Your GP can arrange a full blood count and iron studies to confirm whether you are iron deficient. Identifying and treating iron deficiency early may help prevent progression to anaemia and improve your energy levels and overall wellbeing.
How a telehealth GP can help with iron deficiency
A telehealth GP can efficiently manage iron deficiency without requiring an in-person visit. During your consultation, your GP can discuss your symptoms, review your diet and medical history, and provide a pathology referral for blood tests. Once results are available, a follow-up appointment can be used to discuss your results and treatment plan.
Your GP can prescribe iron supplements, provide dietary advice, investigate potential underlying causes, and arrange specialist referrals if further investigation is needed. They can also monitor your progress with follow-up blood tests to ensure your iron levels are improving.
Treatment options for iron deficiency
Treatment typically begins with iron supplementation. Your GP will recommend an appropriate dose and formulation based on the severity of your deficiency and your individual circumstances. They may also provide guidance on how to optimise iron absorption, such as taking supplements with vitamin C and avoiding certain foods or drinks that may reduce absorption.
Dietary modifications may also help. Your GP can discuss iron-rich foods and dietary strategies to support your iron levels alongside supplementation. For vegetarians and vegans, specific advice on plant-based iron sources and absorption enhancers may be provided.
Identifying and addressing the underlying cause is also important. Your GP may investigate potential causes such as heavy periods, gastrointestinal blood loss, or absorption issues. In some cases, referral to a specialist may be recommended for further investigation or alternative treatment approaches such as iron infusions.
