09 | Why Am I So Tired All the Time? The Truth About Iron & Thyroid


Listen Later

If you’ve ever found yourself saying “I’m just so tired all the time” - you’re not alone.

Fatigue is the number one complaint I hear from women, yet too often it gets brushed off as “just being a busy mum” or “just getting older.”


But here’s the truth: constant exhaustion is not normal. And if your doctor has told you that your blood tests are “fine” but you still feel drained, there’s a good chance you’ve been dismissed or misdiagnosed.


Two of the biggest and most overlooked drivers of fatigue in women are iron deficiency and hypothyroidism. Both are underdiagnosed, both impact far more than just your energy, and both could be the missing piece you’ve been searching for.

In this episode of She Knows Her Body, we’ll cover:

  • Why “normal” blood test ranges don’t always mean optimal health.

  • The key roles of iron and thyroid in your energy, mood, hormones, and metabolism.

  • The most common (and often ignored) symptoms of deficiency or imbalance.

  • What tests you actually need to get accurate answers.

  • Practical ways to support your iron and thyroid so you can finally reclaim your energy.


Your exhaustion is not in your head, and it’s not something you just have to put up with. When you understand your biology, you stop blaming yourself — and start taking back your power.


Because you deserve to feel energized, clear, and strong.
