You’ve tried sleeping more. You’ve cut back on coffee, then upped it again out of desperation. You’ve told yourself it’s just a busy season of life. But if you’re still dragging yourself through every day, it might be worth asking a different question: could this actually be low iron?
Iron deficiency is far more common than most people realise โ it’s thought to affect over a billion people worldwide, and a huge number of them have no idea that’s what’s going on. Here’s what to look out for.
Quick Self-Check: Tick What Sounds Familiar
Grab a mental (or actual) tally as you read through these. The more you recognise, the more worth mentioning to your GP or clinician.
- Fatigue that sleep doesn’t fix
- Brain fog โ struggling to concentrate or feeling mentally “slow”
- Pale skin, or looking “washed out”
- Breathlessness doing things that never used to bother you
- Hair thinning or noticeably more shedding than usual
- Restless legs, especially at night
- Cracked skin at the corners of your mouth
- Cold hands and feet more often than seems normal
- Craving or chewing ice (this one surprises people, but it’s a genuinely recognised sign)
Ticked three or more? That’s worth a conversation with a clinician โ not a diagnosis, just a reason to get it checked.
Why Does This Happen?
Iron isn’t just about “energy” in a vague sense โ it’s what your red blood cells use to carry oxygen around your body. When iron runs low, your whole system is quietly running on less oxygen than it needs, even if nothing shows up on the outside. That’s why the symptoms can feel so disconnected โ fatigue, brain fog, and restless legs don’t obviously seem related, but they all trace back to the same root cause.
Who’s Most Likely to Be Affected?
Certain groups are at higher risk, including:
- Women with heavy periods
- People who are pregnant, particularly in the second and third trimester
- Vegetarians and vegans
- Regular blood donors
- People with digestive conditions that affect absorption (like coeliac disease or IBD)
- Endurance athletes
If you fall into one of these groups and recognised a few symptoms above, it’s genuinely worth getting your iron levels checked with a simple blood test โ it isn’t something you have to just live with.
What Actually Confirms It?
Feeling exhausted doesn’t automatically mean low iron โ plenty of things cause fatigue. The only way to know for sure is a blood test checking your ferritin levels (your iron stores) as part of a proper clinical assessment. This isn’t something to self-diagnose or self-treat โ it’s the first step your clinician takes before recommending anything.
What Happens Next?
If a blood test does confirm iron deficiency, there are a few different paths depending on how severe it is and what’s causing it โ from dietary changes and iron tablets, through to iron infusions for people who need a faster, more direct route. We’ll cover exactly what an iron infusion actually involves in our next post โ including what it feels like, how long it takes, and the questions patients ask us most.
