Our story

New weight-loss treatments changed what was possible. But as GPs, we could see what was missing around them.

Every day, we saw people navigating weight gain alongside hormonal changes, insulin resistance, long-term health conditions and years of losing weight and putting it back on. And more and more people were starting weight-loss treatment without the ongoing support to manage side effects or protect their muscle, bone, skin and hair.

We knew weight care could be better. It needed to look beyond the scales and the prescription, and consider the wider health of each person.

So more than 100 GPs came together to help shape and found Genwell: the kind of service we'd want for our own patients, friends and families. It’s a service where your own GP, nutritionist and wellbeing coach work together to look after the whole of you – not just your weight or your prescription.

Our belief

The healthiest outcomes come from understanding everything that shapes your weight and your long-term health. That belief sits behind everything we do.

We believe your weight is shaped by biology, not a lack of willpower.

We believe a prescription is a start, not a plan.

We believe good nutrition is about nourishing your body, not simply eating less.

We believe success is measured in more than kilos: in strength, energy, confidence and a calmer relationship with food.

We believe your care should fit you, not the other way round.

We believe no one should have to do this alone.

That's why every Genwell patient has their own care team, and why we look beyond the scales from day one.

Built around medical expertise

Our roots are in general practice, and doctors still shape every decision we make: which treatments we offer, how we prescribe them, the wider health issues we look at and the support we build around them.

But no single discipline has all the answers. So we bring medicine, nutrition and behaviour change together, and keep learning from each other and from the people we care for. As the science of weight and metabolic health moves on, so do we. The latest evidence, clinical experience and what our patients tell us all shape how we care for you.

Our ambition is simple: a future where weight care is never treated in isolation, but as part of your whole health.

My work is shaped by 25+ years building patient-centric health businesses in the UK.

Dr Kartik Modha

Co-Founder and Chief Medical Officer

My work is shaped by over two decades of clinical experience and by seeing the limits of fragmented care. I don’t believe metabolic health is about willpower alone. Hormones, sleep, stress, insulin resistance, and daily pressures all matter. My focus is personalised, evidence-based care that addresses root causes and supports long-term health.

Dr Caroline Butler

GP and Chief Clinical Officer

I work with people facing complex health challenges. Hormones, insulin resistance, stress, and long-term dieting often make progress feel difficult. I believe sustainable change comes from combining medicine, lifestyle, and behaviour change techniques. My approach is safety-first, evidence-based, and focused on lasting wellbeing.

How we’re helping

“Starting a GLP-1 has changed my life. I feel healthier, have more energy and know I’ve reduced my risks.

Genwell has given me personalised support with a really understanding GP guiding me through. My health coaching experience has been really priceless - I've made real habit changes that have stood the test of time, and in a supportive and unjudgmental way.

I can't recommend it enough."
