I understand

You are not imagining it, and you are not alone.

You may have already seen several doctors, been told your blood tests are normal, or been advised that stress could be involved.

Feeling unwell when tests look reassuring is not the same as having nothing wrong. It means the next step should be thoughtful: review what has been checked, look for important gaps and avoid testing for testing’s sake.

What is Functional Medicine?

Functional medicine is a way of assessing symptoms by looking at how they have changed over time, alongside factors such as diet, sleep and medicines. If you have persistent bloating, for example, Dr Stavy may ask whether it changes after meals and review any tests you’ve already had. Together you can decide whether further investigation would be useful.

A useful starting point

Persistent fatigue and low energy

Fatigue can have medical, sleep-related, psychological, medicine-related and lifestyle contributors. The first step is a structured review of the pattern, previous results and any red flags, without assuming one hidden cause.

A useful starting point

Gut health and digestion

Bloating, bowel changes, reflux and food concerns can have many causes. A careful history and conventional medical assessment come first, with targeted testing only when it is likely to change the plan.

A little about me

Functional Medicine Doctor, London

I became a doctor to help people feel better, and I never let go of that.

I qualified in conventional medicine and have spent 20 years in practice. Along the way I learned something simple: people receive better care when somebody takes time to hear the whole story.

Tests only help when they answer a useful question. Treatment should have a clear reason. And when conventional care is the right route, that remains part of the plan.

This is a personal medical practice. You see one doctor, your history stays connected and follow-up is built around what happens next.

Frequently asked questions

Where is your functional medicine clinic in London?

The central London clinic is on the first floor at 85 Great Portland Street, London W1W 7LT. Dr Stavy also sees patients at the Women’s Wellness Centre in Chelsea. Check the clinic locations and the address on your appointment confirmation before you travel.

How does lifestyle medicine fit into a functional medicine approach?

Lifestyle medicine looks at how habits such as sleep, eating and physical activity affect your health. If tiredness is your main concern, for example, Dr Stavy may ask about shift work or broken sleep alongside your symptoms, medicines and recent blood results.

Will I need functional medicine testing?

Bring any recent test results you have. Dr Stavy reviews them with your medical history before suggesting further functional testing. You can ask what a test would change about your care and what it costs. Laboratory tests are charged separately.

What is the difference between nutritional therapy and personalised nutrition?

A nutritional therapy consultation focuses on what you eat and what you want help with. Personalised nutrition means tailoring advice to you, including your health needs, budget and the meals you usually eat. Ask who would provide your appointment when you enquire.

What is the difference between a functional medicine practitioner and a functional medicine doctor?

People with different professional backgrounds use the term ‘functional medicine practitioner’. If you want to see a doctor, you can check their medical registration and UK licence to practise on the General Medical Council register.

Can I book a consultation if I already have a chronic illness?

Yes. Bring your medicines list, recent results and any letters from your GP or specialist. You can use the appointment to discuss the symptoms that affect you most and how any suggested next steps fit with your existing treatment plan.
