5th January, 2026Do You Need an Iron Infusion? Signs of Low Iron You Shouldn’t Ignore

Feeling exhausted no matter how much sleep you get? Finding it harder to focus at work? You might brush these symptoms off as just part of a busy life, but they could be telling you something important. 

Iron deficiency is one of the most common nutritional deficiencies in Australia, and many don’t even realise they have it.

While dietary changes and supplements can help boost iron levels for some, others may need a more direct solution: iron infusion therapy. Understanding the signs of low iron and when to seek help can make a real difference to your energy and overall quality of life.

What Is Iron Deficiency?

Iron is an essential mineral that your body needs to produce haemoglobin, the protein in red blood cells responsible for carrying oxygen throughout your body. When your iron levels drop too low, your body can’t make enough healthy red blood cells, leading to iron deficiency anaemia.

Certain groups are at higher risk, including women with heavy periods, pregnant women, people with gastrointestinal conditions, and those with chronic health conditions.

Common Iron Deficiency Signs You Shouldn’t Ignore

Recognising the signs of low iron early can help you get treatment sooner and feel better faster. Here are the key symptoms to watch for:

Persistent Fatigue and Weakness

This is often the most noticeable symptom. If you’re feeling constantly tired, even after a full night’s sleep, low iron could be the culprit. This exhaustion happens because your body isn’t getting enough oxygen to fuel your cells and organs properly.

Pale Skin and Nail Beds

Iron deficiency can cause your skin to lose its healthy colour, appearing noticeably paler than usual. Your nail beds, the inside of your lower eyelids, and even your gums may also look paler. This happens because less haemoglobin in your blood means less of the red colour that gives your skin its normal tone.

Shortness of Breath

Finding yourself breathless during activities that never used to bother you? When iron levels are low, your body struggles to deliver oxygen to your muscles. This means even simple tasks like climbing stairs can leave you feeling winded.

Dizziness and Lightheadedness

Low iron levels can affect blood flow to your brain, leading to feelings of dizziness, particularly when you stand up quickly. Some people also experience frequent headaches as their brain tries to cope with reduced oxygen supply.

Cold Hands and Feet

If your hands and feet always feel cold, even in warm weather, it might be related to iron deficiency. Poor oxygen circulation means your extremities aren’t getting the warmth and energy they need.

Brittle Nails and Hair Loss

Iron plays a crucial role in maintaining healthy hair and nails. When levels drop, you might notice your nails becoming brittle or developing ridges. Hair may become dry, brittle, or fall out more than usual.

Unusual Cravings

Some people with iron deficiency develop cravings for non-food items like ice, dirt, or starch. This condition, called pica, should be addressed with a healthcare professional.

Difficulty Concentrating

Brain fog, poor concentration and difficulty remembering things can all stem from low iron levels. Your brain needs oxygen to function optimally, and iron deficiency can interfere with cognitive performance.

Restless Legs Syndrome

That uncomfortable urge to move your legs, especially at night? It’s been linked to iron deficiency. If you’re experiencing restless legs along with other symptoms, it’s worth getting your iron levels checked.

When Dietary Changes Aren’t Enough

While eating iron-rich foods like red meat, leafy greens and legumes can help maintain healthy iron levels, sometimes diet alone isn’t sufficient. Oral iron supplements can cause side effects like constipation and nausea. Additionally, some people have difficulty absorbing iron through their digestive system.

This is where iron infusion therapy becomes an effective solution. An iron infusion delivers iron directly into your bloodstream, bypassing the digestive system entirely. This allows for rapid replenishment of iron stores and faster relief from symptoms.
