The pattern spotter

If three or more of these are yours, you're in the right place.

These rarely travel alone — they cluster, in the same body.

Tired but wired, can't switch off
Cold hands, dry skin, hair thinning
Brain fog, words won't come
Weight that won't shift no matter what you try
Bloating, gut weirdness, food sensitivities
Cycles all over the place
Period pain that floors you
Anxiety, rage, weepy by 5pm
ADHD or autism — you, or a child
Dizzy on standing, faint, racing heart
Bendy joints, achy after exercise
Sleep that's broken, shallow, or never enough
About Caitlin

A patient doctor mum functional medicine practitioner.

Dr Cait Wiltsher

Caitlin is a functional medicine practitioner, mum to four boys, and a hospital-trained doctor (MBBCh). She trained and worked in the NHS, and is grateful for the patients she cared for. But ten-minute appointments were never going to be the right shape for the questions some of her patients — and, honestly, she herself — were carrying.

Functional medicine gave her the lens that fit. It increased her knowledge and desire to look at the whole picture — the thyroid, the gut, the nervous system, the immune system. Once you see the clusters, it stops feeling like you're broken in twelve different ways. It starts feeling like one story — and one you can finally start working with, instead of against.

Caitlin sees clients online from Perth, across the UK and Australia. Within Cura Body, she works in the role of a functional medicine practitioner — not as your prescribing doctor. This is functional medicine education and lifestyle work, designed to sit alongside your medical care, not replace it. Anything that needs a diagnosis, a prescription or a referral stays with your GP and specialists, where it belongs.

Ready to change your health for the better.

Week 0

Before we meet

Caitlin's clients fill in a comprehensive intake form — your health concerns, health goals, when you last felt well, what your sleep and your diet actually look like. Most clients tell Caitlin the questionnaire actually helps them see their health as a whole, and can feel quite cathartic. Maybe for the first time their whole health story is in one document — not split across half a dozen specialists and GP appointments.

Week 1

The consultation

A 60–90 minute consultation. Caitlin deliberately leaves it up to 90 minutes so nothing has to be rushed and you can feel properly seen and heard.

Week 2

Testing, supplements and your personalised plan starts

The week after our consultation, you receive your written plan, along with any functional testing and practitioner-grade supplement recommendations — not expectations. You decide what you want to take forward.

Week 6

Review and your long-term plan

A 45-minute follow-up. We review how the plan has gone and your personalised test results. Then we go even deeper, with further personalised root-cause interventions based on your unique genetic, environmental and lifestyle picture. You leave with a long-term plan written for you: your patterns, your levers, your early-warning signs — so you can carry this forward, not just for six weeks.

After the 6 weeks

The door stays open

Most of Caitlin's clients dip in again when life gets loud — a stressful year, a big change, perimenopause, a new diagnosis in the family. You'll know your system well enough by then to know when it's time.

Sign up

Six weeks from now.

You could feel lighter. You could have your energy back. And you could finally understand your own body, the dots finally connected, and the tools to keep going long after we're done.

Before you book

Frequently asked questions.

Will I lose weight?

Often, yes — but not because we're targeting weight. Weight that's been stuck (usually because of inflammation, thyroid, insulin, cortisol or sleep) tends to shift once the system underneath it is properly supported. We work on the cause. The weight tends to follow.

Will this help with fertility?

I've worked with many clients trying to conceive while also navigating PCOS, hypothyroidism, coeliac disease and other conditions that quietly get in the way. If fertility is your aim, I'll always suggest getting your partner involved too — three to six months of working on this together can make a real difference.

Why does it cost what it does?

Because this isn't a plan that targets one symptom or one system. It looks at the whole picture, for long-term impact — and that takes time, depth and real commitment from both of us. The price reflects what I bring to the six weeks, and what I'm asking you to bring too.

Do you work with neurodivergent people?

Yes — Caitlin has worked with many neurodivergent clients. If you're looking for a more family-centred approach, that lives over at drcaitwiltsher.com.
