One number is not your whole thyroid
Your thyroid tests came back “normal”. You still feel rubbish!
There's usually a reason
AND it's often sitting in the part of the picture nobody measured.
Your thyroid is that butterfly-shaped gland quietly running the show behind the scenes.
When it's not firing on all cylinders you can feel absolutely rubbish - exhausted, foggy, cold when nobody else is, hair thinning, weight that won't budge - even when your doctor says your tests look fine.
Here's the thing most people are never told.
Standard testing usually measures TSH, & sometimes T4. TSH is your brain's message to your thyroid – essentially "Hey thyroid, wake up!" Then it’s telling your thyroid to “Make more (or less) hormones”. TSH tells us the message was sent. It tells us nothing about whether your body converted your inactive hormone into the active form needed to do the work, or whether the active hormone is actually getting inside your cells to do its job.
It's like confirming your phone has a full battery, but never checking whether it can connect to the network – or whether your apps actually run.
So if you've been told everything's normal & you still feel dreadful, you're not imagining it. You've just had 1 part of a 3-part picture measured.
The first job, then, is to get the fuller set of numbers & read them properly. Most people have never had that done. And then comes the part almost nobody mentions. Even with a complete set of results in front of us, there is far more to how your thyroid actually functions than any blood test can show.
Your bloods tell us what is happening. They can't tell us why – & with thyroid, the why is very often somewhere else in your body altogether.
That's not a reason to skip the bloods. It's the reason to start there, & then keep going.
Sound Familiar?
You're exhausted in the morning no matter how long you slept
You're cold when everyone else is fine, & your hands & feet never quite warm up
The weight won't shift, however carefully you eat
Your hair is thinning, your skin is dry, your nails break
Brain fog has become your normal, & you've started making lists for things you'd never have forgotten
Your TSH came back "within range", so the conversation ended there
Maybe you're on medication, & feel better than you did – but nowhere near well
The good news?
A great deal about thyroid function is genuinely influenceable. Not the gland itself, necessarily – but the conversion, the transport, the cellular uptake, & the nutrients the whole process runs on. That's a lot of levers, & most of them are within reach.
THE WHOLE SYSTEM, NOT JUST THE GLAND
YOUR THYROID ANSWERS TO YOUR GUT, YOUR STRESS LOAD & YOUR NUTRIENT STATUS. ALL OF IT GETS LOOKED AT – NOT JUST THE ONE NUMBER.
PROOF IT'S WORKING
WE TRACK YOUR SYMPTOMS EACH MONTH, NOT JUST YOUR NUMBERS – & REPEAT BLOODS WHEN THE TIMING'S RIGHT. YOU'LL SEE WHAT'S SHIFTED, INCLUDING THE THINGS YOU'D STOPPED NOTICING.
If you’re already on it, your medication stays your doctor's domain. My work is everything around it.
A PLAN BUILT ON YOUR RESULTS
FOOD, SLEEP & STRESS FIRST, THEN THE NUTRIENTS & HERBAL SUPPORT YOUR OWN BIOCHEMISTRY CALLS FOR. NOT A GENERIC THYROID PROTOCOL.
The 3 Questions that Matter
Your thyroid hormones have to clear 3 hurdles before you feel the benefit. Standard testing only checks the first.
Are you making enough?
Your thyroid produces mostly T4 – the storage form – plus a little T3, the active one. This is the part standard testing looks at, & it's a genuinely useful starting point.
Your bloods answer this question well.
Are you converting it?
T4 has to be converted into T3 before it can do anything useful. Under stress, inflammation or nutrient shortfalls, your body can make reverse T3 instead – the evil twin – which tells your system to slow everything down & conserve energy.
Your bloods can show us whether this is happening. Not why – & the why is where the fixing happens.
Is it getting into your cells?
This is the part nobody measures. Hormones can look perfectly respectable in your bloodstream & still not be getting inside your cells to do their job. That needs working cellular energy production, the right transporters, & vitamin A-dependent receptors – the welcome mat at the cell door.
Your bloods can't show this at all.
2 KEYS - 1 LOCK. REVERSE T3 COMPETES WITH ACTIVE T3 FOR THE SAME LANDING SPOTS ON YOUR CELLS.
PRODUCTION. CONVERSION. CELLULAR UPTAKE.
GET ALL 3 RIGHT & YOU FEEL FANTASTIC.
MISS 1 & YOU DON’T - WHATEVER YOUR TSH SAYS!
Your bloods open the investigation.
The rest of it is a conversation.
Your Thyroid Rarely Struggles Alone
Here's what I see over & over in clinic:
The thyroid is usually the first system to complain when something else is struggling. It's the canary in the coal mine – or the check engine light, for the younger crowd. Two relationships matter more than any others:
Your gut.
A meaningful share of your T4-to-T3 conversion happens in your gut. Gut inflammation directly affects thyroid function, & the bacteria living there help regulate your thyroid hormones.
Your adrenals.
Chronic stress makes your body prioritise cortisol over thyroid function. High cortisol blocks conversion & pushes production toward reverse T3. Stressed adrenals & struggling thyroids turn up together so often they're practically a package deal.
And in perimenopause the whole thing gets more interesting again. When oestrogen starts waving goodbye, your thyroid often throws a bit of a wobbly too – these hormones are practically besties.
This is why treating the thyroid alone so often disappoints. Supporting a struggling thyroid while ignoring stressed adrenals or an inflamed gut is like bailing out the boat without ever finding the leak. You can do it for years, & you'll be tired for all of them.
Which is also why your bloods are the beginning of this conversation, not the end of it.
If You’re Already on Thyroid Medication
If you're on levothyroxine or similar & still feel like you've been hit by a bus, you are absolutely not alone.
Your medication supplies T4. Your body still has to convert it, transport it, & get it inside your cells – & every one of those steps can be blocked by the things above. You can be perfectly medicated & still unwell.
To be completely clear: your medication is prescribed & adjusted by your doctor, & that's exactly where it belongs. Nothing here involves stopping or changing it.
What I work on is everything around it – the conversion, the nutrients, the gut, the stress load. With your permission, results & recommendations can be shared with your GP or specialist so everyone's working from the same information.
So What Actually Happens
STEP ONE
Read your bloods properly
Your Pathology Analysis reviews your existing results through an optimal-function lens: the full thyroid picture where it's available, plus your iron story (critical), zinc, vitamin D, B12 & the inflammatory markers your thyroid depends on.
But numbers on their own don't mean much. The same result can mean 2 completely different things in 2 different people. So your results are read alongside your symptoms, what you're finding hard day to day, anything you've already been diagnosed with, & whatever you're already taking. That's the context that turns a set of numbers into an actual picture.
You'll get a written Results & Recommendations Report. For some people this is enough – real answers, a clear direction, & changes you can start on straight away..
STEP TWO
Find out why
Step one tells us what is happening, & for a good number of people that's genuinely where the penny drops. But it almost always raises a sharper question: why is this happening to you?
Why isn't the conversion working? What's driving the inflammation? Why is your body behaving as though it needs to conserve energy?
That's what The Wellness Kickstart is for. Your whole story, properly heard – your history, your stress, your gut, your sleep, your symptoms, what you've already tried & what happened when you did. This is where the pattern usually becomes obvious. Where it adds real insight, targeted functional testing goes deeper.
Your bloods pointed us in the right direction. This is where we work out what to do about it.
STEP THREE
Support it, then check
Food & nutrients first. The things your thyroid genuinely needs are non-negotiable, & they come from your plate before they come from a bottle. Targeted herbal & nutritional support where your results call for it, chosen for you & checked against any medications.
Then we watch what actually changes. Your symptoms get tracked month by month – energy, temperature, sleep, mood, hair, digestion, how your brain is behaving – & I'll tell you what's shifting. That matters more than you'd think, because improvement is gradual & people genuinely forget how bad things were. One of my favourite parts of this work is pointing out something that's quietly resolved while you weren't looking.
And when the timing's right, repeat bloods to confirm it in black & white.
Hashimoto’s & Grave’s - Autoimmune Thyroid
If your antibodies are raised, the conversation changes. The thyroid isn't really the problem – it's the target. The question becomes why your immune system is behaving this way.
Hashimoto's is the common one. In countries like New Zealand & Australia it's behind most underactive thyroids. The immune system gradually slows the thyroid down, & the picture is the familiar one: exhaustion that sleep doesn't fix, weight that won't budge, feeling cold when nobody else is, dry skin, thinning hair, constipation, brain fog & low mood. Many people have it for years before anyone diagnoses it, because TSH can stay respectable for a long while as antibodies quietly climb.
Graves' works the other way. The immune system drives the thyroid too hard, & the result is the opposite picture: racing heart, weight dropping off you, heat intolerance, shakiness, anxiety, trouble sleeping, sometimes changes to the eyes. It needs medical management, & that is not negotiable.
What both have in common is that the immune system is the thing worth understanding. That's where investigation earns its keep: gut integrity, inflammatory drivers, nutrient status, stress physiology, & sometimes environmental factors. There's also a well-recognised relationship between gluten & autoimmune thyroid conditions, worth exploring properly rather than guessing at.
None of this replaces medical management, & with Graves' in particular your specialist leads. My work sits alongside theirs, on the terrain the medication doesn't reach.
How it Usually Works
Most people start in the same place, then take whichever next step actually fits. There's no package to sign up to & no set number of appointments – just a sensible order.
1. Start with your bloods
Your Pathology Analysis is the foundation – your results read for optimal function, with a written report & clear next steps. A complete standalone service, & for many people it's all they need to get moving.
2. Go deeper if it's warranted
Where your picture is more complex, or you want the full story heard properly, the Wellness Kickstart is the comprehensive deep-dive – your history, lifestyle & goals woven into a personalised Wellness Plan.
3. Keep it moving
Follow-up consultations are where the real change happens – adjusting as your body responds, troubleshooting what's difficult, & updating your plan each time so progress is visible.
4. Investigate further when it adds real insight
Sometimes standard bloods don't tell the whole story. Targeted functional testing fills specific gaps – gut, hormones, nutrients, cellular energy or genetics – but only where it will genuinely change what we do.
5. Then keep yourself there
Once you're feeling good, an Annual Health Review each year keeps you on track – your yearly WOF, reviewing updated bloods, revisiting goals & refreshing your plan. Healthy ageing isn't a twelve-week project.
Full pricing for each service is on its own page – no packages, no lock-in, & you only ever take the next step if it makes sense for you.

I have been seeing Caro for a 6 months so far and have highly recommended her to a number of people in my life. Caro’s warmth and openness immediately had me comfortable to open up on various health symptoms and together, with an extensive blood test and lifestyle tracking, she was able to a identify and start treating the sources of a lot of these symptoms.

Frequently Asked Questions
What is Hashimoto's thyroiditis?
Hashimoto's is an autoimmune condition where the immune system gradually attacks the thyroid, slowing it down over time. It's the most common cause of an underactive thyroid. It's diagnosed by testing thyroid antibodies (TPO & thyroglobulin) alongside thyroid hormones – & because antibodies can be raised for years before TSH shifts, plenty of people feel unwell long before anyone diagnoses it. Diagnosis & any medication are your doctor's domain. What I look at is everything influencing the immune picture underneath: gut health, inflammation, nutrient status & stress physiology.
What is Graves' disease?
Graves' is the other side of the autoimmune coin. Instead of slowing the thyroid down, the immune system drives it too hard, producing an overactive thyroid. Typical signs include a racing heart, unexplained weight loss, feeling hot when others don't, shakiness, anxiety & poor sleep, & sometimes changes to the eyes. Graves' needs medical management & your specialist leads – please don't delay that. Alongside their care, there's useful work to be done on the things that influence immune activity & on replenishing what an overactive thyroid burns through.
My TSH is normal – can I still have a thyroid problem?
Yes, & it's more common than you'd think. TSH is your brain's message to your thyroid, not a measure of what's reaching your cells. You can have a perfectly respectable TSH while your active T3 sits at the bottom of the range, or while thyroid antibodies are quietly climbing. This is exactly why looking at the fuller picture matters.
What is a full thyroid panel?
TSH, Free T4, Free T3, reverse T3 & thyroid antibodies (TPO & thyroglobulin) – ideally alongside full iron studies, zinc, vitamin D & B12, since thyroid hormone production & conversion depend on them. Not every marker is routinely funded, & we'll talk through what's realistic for your situation.
Will my GP order all of these?
Sometimes yes, sometimes not – funding rules mean some markers aren't routinely covered. The pathology request form includes what's most useful, & an honest conversation about wanting to understand your own health usually goes down well. Where markers aren't available through your GP, self-funded options exist & we can discuss them. It also helps to advise your GP if you have any family history of autoimmune disease.
Can a naturopath help with hypothyroidism or Hashimoto's?
Naturopathy doesn't replace medical diagnosis or management of thyroid disease – & it shouldn't. What it can do is investigate & support everything around it: conversion, nutrient status, gut health, inflammation & stress physiology. For a lot of people, that's where the real work sits.
I'm on levothyroxine & still feel terrible. Why?
One of the most common reasons people get in touch. Medication supplies T4 - your body still has to convert it to active T3, transport it, & get it into your cells – & that depends on nutrients, gut function, liver health & cortisol patterns. If any of those are compromised, you can be well medicated & still unwell. Worth investigating, with your prescriber staying in charge of the medication itself.
Will you tell me to stop my thyroid medication?
Never. Medication is prescribed & adjusted by your doctor, & that stays exactly as it is.
Does perimenopause affect my thyroid?
Often, yes. As oestrogen starts declining, the thyroid frequently throws a bit of a wobbly too – these hormones are closely connected. Your thyroid also becomes more sensitive to stress, nutrient gaps & any lurking autoimmunity during this transition. Looking at both together tends to work far better than tackling either alone.
Can you help if I don't live on the Kapiti Coast?
Absolutely. Around half of all clients work with me entirely online, from all over New Zealand & Australia. Test kits, if functional testing is of interest, are couriered to your door.
