Feeling exhausted is one of the most common reasons people come to see us. And while there are plenty of things that can cause fatigue, iron deficiency is one of the most frequently missed.
It’s not that doctors don’t check for it. It’s that a lot of people assume being tired is just part of life. Work, kids, stress, late nights. They push through, drink more coffee, and put it down to being busy.
Sometimes that’s true. But if the tiredness doesn’t shift no matter how much sleep you get, iron deficiency is worth ruling out.
What Does Iron Actually Do?
Iron is essential for making haemoglobin, the protein in red blood cells that carries oxygen around your body. When your iron levels drop, your body struggles to get enough oxygen to your muscles and organs. The result is fatigue that goes beyond normal tiredness.
Low iron exists on a spectrum. You can have depleted iron stores without being anaemic, and still feel genuinely unwell. A full iron study, not just a basic blood test, gives a much clearer picture of where your levels actually sit.
Symptoms of Iron Deficiency
The symptoms can be surprisingly wide-ranging. Common ones include:
- Persistent tiredness or exhaustion that doesn’t improve with rest
- Difficulty concentrating or brain fog
- Shortness of breath during activities that shouldn’t wind you
- Pale skin
- Headaches
- Cold hands and feet
- A rapid or irregular heartbeat
- Brittle nails or hair loss
- Restless legs, particularly at night
- Cravings for non-food items like ice, dirt, or chalk (this is called pica and is a classic sign of significant iron deficiency)
Not everyone gets all of these. Some people feel mainly tired. Others notice the brain fog more than the physical symptoms.
If any of this sounds like you, it’s worth getting checked. Book an appointment at Southport Metro and we can run a full iron study. Book online or call 07 5612 7830.
Who Is Most at Risk?
Iron deficiency is more common than most people realise. Groups at higher risk include:
Women with heavy periods, as monthly blood loss is one of the most common causes of iron deficiency in women of reproductive age.
Pregnant women, because iron requirements increase significantly during pregnancy.
People who follow a vegetarian or vegan diet, as iron from plant sources is less readily absorbed than iron from meat.
People with gut conditions like coeliac disease, Crohn’s disease, or a history of gut surgery, as these affect how well iron is absorbed.
Regular blood donors, endurance athletes, and adolescents going through rapid growth spurts are also at higher risk.
How Is It Treated?
Treatment depends on how low your levels are and what’s causing the deficiency.
For mild to moderate iron deficiency, oral iron supplements are usually the first step. They work well but do take time, typically several months to fully restore iron stores. Some people experience gut side effects like constipation or nausea, which your GP can help you manage.
When oral iron isn’t tolerated, isn’t absorbing well, or levels are significantly depleted, an iron infusion is an option. At Southport Metro, we offer iron infusions onsite, which means you don’t need to go to hospital to get one.
Want to know if an iron infusion is right for you? Come in and we’ll check your levels and talk through the options. Book online or call 07 5612 7830.
Finding the Cause Matters
Treating low iron without understanding why it’s low means it’s likely to come back. Your GP will look at the underlying cause, whether that’s diet, absorption, blood loss, or something else, and address that as part of the plan.
