Do I Need an Iron Infusion? What to Know
Could low iron be behind how you’re feeling? Find out when an iron infusion may be considered and what to expect before, during and after.
Low iron can show up in everyday life before you know what’s causing it. You might feel unusually tired, lose concentration at work, get out of breath more easily, or notice your usual energy isn’t there.
Could low iron be affecting you?
Signs can include:
- Feeling unusually tired despite sleeping normally
- Getting breathless walking uphill or climbing stairs
- Headaches or feeling light-headed
- Finding it harder to concentrate
- Restless legs, particularly at night
- Craving or chewing ice*
- Heavy or frequent periods
Low iron can affect women and men.
For men, low iron can show up as lower energy, reduced exercise stamina, trouble concentrating, or feeling unusually tired after a normal day.
For women, heavy periods and pregnancy can lower iron levels. Women’s Health Week is a timely reminder that ongoing tiredness or breathlessness can sometimes be linked to low iron.
*Why would you crave ice? Craving or chewing ice is called pagophagia and is linked with iron deficiency, although exactly why it happens isn’t fully understood.

How doctors check for low iron
A blood test called iron studies can help your doctor assess your iron levels. This usually includes a ferritin test, which helps show how much iron your body has stored.
Your doctor considers these results alongside your symptoms and why your iron may be low.
Iron tablets or an iron infusion?
Low iron doesn’t automatically mean you need an infusion.
Iron tablets may be recommended first. An infusion may be considered if tablets don’t suit you, cause side effects, aren’t working well enough, or your iron needs to be replaced more quickly.
What happens during an iron infusion?
At Turbot Street Medical Centre, the process starts with a 20-minute pre-consultation. Your doctor assesses whether an infusion is suitable and prescribes the iron if required.
You then return on another day for the infusion, which usually takes around 20–30 minutes.
What might you notice afterwards?
If iron deficiency has been contributing to your symptoms, treatment may help improve symptoms such as:
- Low energy or ongoing tiredness
- Difficulty concentrating
- Shortness of breath during activity
- Reduced exercise tolerance
- Restless legs
Improvement isn’t always immediate, and results vary between people. Your doctor can explain what to expect based on your iron levels, symptoms and the cause of your iron deficiency.
Iron infusions can also cause side effects. Some people may experience a headache, nausea, dizziness, flushing or muscle and joint aches.
One uncommon but important risk is skin staining if iron leaks into the tissue around the infusion site.
Can food increase your iron?
Iron-rich foods include meat, seafood, legumes, tofu and iron-fortified cereals. Vitamin C can also help your body absorb iron from plant foods.
Food alone, however, may not correct an established deficiency, particularly when blood loss or difficulty absorbing iron is involved.
