Feeling tired all the time? Struggling to concentrate? Getting breathless during everyday activities? While these symptoms can have many causes, one often-overlooked culprit is iron deficiency — and it’s more common in Australia than you might think.
Up to 5% of Australians have iron deficiency anaemia, with many more experiencing iron deficiency without anaemia. The condition is particularly prevalent among women of reproductive age, children, and pregnant women.
Why Iron Matters
Iron is essential for transporting oxygen throughout your body. When your iron levels drop, your body can’t make enough healthy red blood cells to carry oxygen efficiently. This leads to that persistent fatigue that no amount of coffee seems to fix.
Beyond just making you tired, iron deficiency can affect your immune system, cognitive function, and overall quality of life. In children, it can impact growth and development, while in pregnancy, it increases risks for both mother and baby.
Who’s at Risk?
Recent Australian research shows concerning patterns:
- Women under 50: About 10% have depleted iron stores
- Young children: Studies show 15-20% of toddlers are iron deficient
- Pregnant women: Up to 35% develop iron deficiency anaemia
- Indigenous Australians: Face particularly high rates, with some communities showing 55% of women affected
Heavy menstrual periods, rapid growth spurts, pregnancy, and inadequate dietary intake are common contributing factors.
Recognising the Signs
Iron deficiency often develops gradually, so symptoms can be easy to dismiss.
Signs your body may be running low on iron:
- Persistent fatigue and weakness
- Shortness of breath during normal activities
- Pale skin, nails, or inner eyelids
- Restless legs or unusual cravings for ice or starch
- Difficulty concentrating or “brain fog”
Boosting Your Iron Intake
Your body absorbs iron from meat, poultry, and fish (haem iron) much more easily than from plant sources. However, you can improve iron absorption from plant foods by:
- Combining iron-rich foods with vitamin C (think spinach with lemon, or beans with tomatoes)
- Cooking in cast iron pans
- Avoiding tea and coffee with iron-rich meals
Good sources include red meat, chicken, fish, eggs, leafy greens, legumes, and iron-fortified cereals.
When to See Your Doctor
If you’re experiencing persistent fatigue or other symptoms, don’t just assume it’s normal. A simple blood test can check your iron levels. This is especially important for men and post-menopausal women, as iron deficiency in these groups may indicate underlying health issues requiring investigation.
