About Dr. Harriet Campbell
Gut Health & Digestive Health Specialist
Struggling with bloating, digestive discomfort, or gut health issues that just won’t go away? You’re not alone—and you don’t have to figure it out by yourself. I’m Dr. Harriet Campbell, a specialist in gut health & digestive health, here to help you feel better, regain your energy, and take back control of your well-being.
I am both a medical doctor and also a registered nutritional therapist. I have been an NHS GP for 28 years, and have worked with many people with chronic digestive issues such as bloating, acid reflux, constipation/diarrhoea, tiredness and abdominal discomfort, resulting in being diagnosed with a catchall label of Irritable Bowel Syndrome.
I have witnessed first-hand their frustration when conventional medical treatment repeatedly fails to deliver a real improvement. To improve symptoms we need to address root causes and not simply treat symptoms. I wanted to take a different approach with my patients so undertook further training in Functional Medicine with the Institute for Functional Medicine, and to additionally qualify as a Nutritional Therapist with the College of Naturopathic Medicine.
My approach is based on the foundational Functional Medicine principles of considering the specific impact of nutrition, lifestyle, environment, genetics and psychology on each individual’s health.
Every person is different, meaning that their health will be affected in different ways. So, one condition may have many causes and one cause may result in many conditions.
This personalised approach enables treatment to be targeted at the root causes of symptoms for that individual patient. My years of experience in General Practice, in combination with my nutritional therapy training, places me in the unique position of fully understanding and appreciating your health journey on all levels, and hence working effectively with you to transform your digestive and gut health.

My Approach to Gut Health & Digestive Health
Qualifications & Affiliations
I believe that good digestion is the foundation of overall health. When your gut is balanced, everything feels better—your energy improves, your skin clears up, and your mood stabilises. But when your digestive health is off, it can lead to bloating, diarrhoea, constipation, acid reflux, discomfort, brain fog, and even long-term health issues.
Through my work, I help clients uncover the root causes of their gut health struggles and create sustainable, science-backed solutions that fit their lifestyle.

What My Clients Say
"As an experienced health and wellness professional who has had on/off gut issues for years, I found it hugely valuable to have someone who is trained in both traditional and functional medicine supporting me.
Harriet has a wealth of knowledge but above all else, genuinely takes the time and care with you as a client/patient.
I cannot recommend Harriet highly enough."
MK, West Midlands
"Having suffered from IBS for about 30 years, I finally decided that I needed help to calm down my misfunctioning gut . Dr Campbell showed me that it was achievable. She taught me what to eat and which nutrients to supplement in order to meet the needs of my fragile digestive system. We also talked a lot about lifestyle intervention.
She was so full of practical, easily actionable advice that my journey towards better health was a real pleasure. I felt supported, encouraged and empowered and I am delighted with the results achieved."
CS, Northamptonshire
"Dr Harriet Campbell gave me back my everyday living and social life. Even my grandchildren were getting concerned about how poorly grandma was. Harriet is kind and understanding."
