Welcome to The Gut Health Doctor, founded by Dr Megan Rossi PhD BHSc RD APD

Gut health is revolutionising our approach to health and wellness, and looking after your gut is one of the most effective ways to enhance overall health and wellbeing.

As a relatively new area for scientific research, taking care of your gut health can seem complicated and overwhelming - especially with all the misinformation and pseudoscience out there.

The Gut Health Doctor is looking to change that. We’re here to get the truth about the gut out in the open in order to make a meaningful difference in people's lives. No complicated science, no magic fixes, and definitely no jargon. Just straight up, easy to understand information and advice from people who know a thing or two about the science of the gut.

Join us on a journey of discovery to learn how to best look after your gut, so that in turn it can look after you.

Megan: My Story

Growing up, good gut health was inherent to my lifestyle – I lived on a farm after all – yet my first conscious memory of the gut wasn’t a happy one.

My world came crashing down when my grandma, the most caring soul, was diagnosed with bowel cancer. I remember watching on helplessly as she bravely battled through chemo and surgery – I hated the gut for doing this to her.

Several years later after losing my grandma, those negative emotions surrounding the gut resurfaced. I was working in a hospital as a dietitian and was struck by the sheer number of patients with kidney disease who were complaining of gut issues. I really struggled to get my head around how, while my grandma had her disease in her actual gut, all these patients also suffered with such prominent gut issues. And it wasn't just those with kidney disease, I was fortunate to also work with Olympic athletes and a number of company CEOs, and found that many of them too suffered with gut issues.

I searched just about every textbook and paper I could find, but still no real answers. I couldn’t let it rest, and soon found myself signing away my early twenties to a PhD in gut health. Fast-forward three years, and it became very clear to me that the gut was not an isolated organ as I had been taught, but in fact central to our overall health and happiness.

Through my PhD, I realised that by nourishing the gut and caring for it, people could improve their lives in very real and often surprising ways, and I could help them to do this. This was the turning point in my relationship with the gut – my eyes were finally opened to its power and promise.

I qualified as a Dietitian back in 2009, and received my PhD with the Dean's Award recognising my contribution to science in 2015. With a wealth and variety of nutrition experience, from working as a clinical dietitian to being appointed as sports nutritionist for the Australia Olympic Synchronised Swimming team, the gut really has stolen my heart. I am now a Research Fellow at King's College London, where I lead research investigating nutrition-based therapies in gastrointestinal health, including pre- and probiotics, dietary fibres, the low FODMAP diet and food additives (read more about my research and the latest gut health news on the Education Hub).

Frustrated that my findings weren't reaching the public, I set up The Gut Health Doctor in 2017. In early 2019, I founded The Gut Health Clinic (Harley Street Precinct, London) and brought together a team of gut-specialist dietitians to make an evidence-based approach accessible to all.

My first book, Eat Yourself Healthy, is available to order now!
