Why Low Iron Is Making You Feel Exhausted

Low iron and low ferritin are incredibly common, particularly among women - but that does not mean they should be ignored.

In this episode of Diet Notes, we take a deep dive into iron: why it matters, what ferritin actually tells us, and why you can feel absolutely exhausted even when your haemoglobin levels are technically “normal”.

We explore the key signs that your iron stores may be low, including fatigue, brain fog, breathlessness, dizziness, poor immune function and that constant feeling of running on empty. We also look at why low ferritin is often under-treated, why “just take a supplement” may not always be enough, and when it may be worth speaking to your GP about further testing or an iron infusion.

This episode also covers the important medical checks to consider if your iron levels are chronically low, including heavy periods, endometriosis, coeliac disease, bowel health, thyroid function and other possible causes of blood loss or poor absorption.

Plus, we look at the dietary side of iron: the difference between haem and non-haem iron, why lean red meat can be so effective for meat eaters, how plant-based eaters can optimise their intake, and the foods that can help support better iron levels over time.

In this episode, we cover:

• Why ferritin matters, even when haemoglobin looks normal
• The common symptoms of low iron and low ferritin
• Why women, teenagers, runners, pregnant women and breastfeeding mums can be more vulnerable
• When low iron needs further medical investigation
• The difference between haem and non-haem iron
• Why supplements may not be enough when ferritin is very low
• When to speak to your GP about iron infusions
• The possible link between low ferritin and higher LDL cholesterol
• Practical ways to include more iron-rich foods across your day

If you have been feeling exhausted, foggy, breathless, dizzy or constantly run down, this is your reminder to check your bloods, know your ferritin level, and advocate for proper support if something does not feel right.
