Thyroid Blood Test Normal… But Still Tired? Here’s What Your GP Might Be Missing

If you're exhausted, gaining weight without reason, foggy, anxious, and frustrated that your GP keeps saying "everything’s normal"- this is for you.

I see you.
And I’ve been you.

At age 17, I was diagnosed with Hashimoto’s - an autoimmune thyroid disorder that affects energy, metabolism, mood, and more. As a women’s health naturopath specialising in thyroid conditions, I help clients every week who’ve been told their thyroid is “fine” when it’s clearly not.

So let’s unpack what’s really going on—and what your blood test might be missing.

What Is the Thyroid, and Why Does It Matter?

Your thyroid is a small butterfly-shaped gland in your neck that plays a huge role in your health. It regulates:

  • Your energy levels

  • Your metabolism

  • Your brain function

  • Your menstrual cycle

  • Even your mental health

When the thyroid slows down (a condition known as hypothyroidism), every system in your body slows down too.

“Your Thyroid Is Fine” — But Is It?

Most GPs only test TSH (Thyroid Stimulating Hormone).
Here’s the problem: TSH isn’t made by the thyroid—it’s made by the brain.
It simply tells the thyroid what to do. It doesn’t tell us how the thyroid is actually performing.

That’s like shouting directions at a car without checking if the engine even works.

Here’s What’s Often Missing:

  1. Free T3 and Free T4 – These are your actual thyroid hormones. They control metabolism, energy, and mood.

  2. Thyroid antibodies (TPO, TgAb) – These can reveal autoimmune thyroid conditions like Hashimoto’s, even before hormone levels change.

  3. Urinary iodine levels – Iodine is essential for thyroid hormone production. I test this in nearly every client with thyroid symptoms.

Why You Still Feel Unwell Even with “Normal” Results

GPs often rely on wide reference ranges that allow for huge variation.
You could be told you’re "in range" when you’re experiencing classic signs of thyroid dysfunction:

Common Signs of Thyroid Imbalance:

  • Fatigue, even after a full night’s sleep

  • Brain fog and forgetfulness

  • Constipation and bloating

  • Low mood, anxiety or depression

  • Weight gain or inability to lose weight

  • Feeling cold all the time

  • Irregular or heavy periods

  • Thinning hair or dry skin

Sound familiar?

You’re not imagining it.
You’re not lazy.
And you absolutely deserve better care.

What Actually Causes an Underactive Thyroid?

There’s rarely one root cause. Often, it’s a combination of:

  • Genetics or family history

  • Autoimmune conditions like Hashimoto’s

  • Past viral infections (e.g. Epstein-Barr virus)

  • Toxin exposure (like fluoride, chlorine, BPA)

  • Chronic stress and burnout

  • Trauma or emotional suppression (throat chakra imbalances)

The Iodine Connection

Iodine is the key mineral your thyroid needs to function.
Most Australians are deficient, due to diets low in seaweed and seafood—and environmental toxins (like fluoride in tap water and toothpaste) can block iodine absorption entirely.

This is why I routinely test urinary iodine for my clients with fatigue, brain fog, and hormonal imbalances.

What To Do If You Suspect a Thyroid Issue But Your Doctor Won’t Test Further

This is where naturopathic care can make all the difference.
I work with clients across Australia to:

  • Run comprehensive thyroid and hormone testing

  • Assess nutrient levels like iodine, selenium, iron, and zinc

  • Identify root causes of dysfunction

  • Create a holistic healing plan (including herbal medicine, food therapy, and lifestyle changes)
