I’m Dr Colette Kirk, a HCPC Registered Dietitian, Lead NHS Specialist Dietitian and PhD-qualified Clinical Nutrition researcher.

I specialise in supporting adults living with digestive symptoms, intestinal failure, liver and hepatobiliary conditions, and fatigue associated with complex gastrointestinal disease. I also provide evidence-based nutritional support for people using GLP-1 medications who want to maintain nutritional adequacy, muscle health and long-term wellbeing during treatment.

Many of the people I work with have been living with ongoing symptoms for months or years. Others are navigating new treatments and want trusted, evidence-based nutrition advice. They’ve often tried multiple diets, received conflicting information or been told their tests are ‘normal’, yet still don’t feel well.

My approach is different. Rather than focusing on unnecessary dietary restriction, I help people understand how nutrition can support symptom management, nutritional adequacy, energy levels and long-term health using personalised, evidence-based advice.

Alongside my clinical practice, I lead specialist NHS services and undertake clinical nutrition research focused on improving quality of life, physical function and nutritional care for people living with complex gastrointestinal conditions.

Whether you’re waiting for investigations, managing a diagnosed condition or looking for specialist nutritional support, including nutrition during GLP-1 treatment, my aim is to help you make confident, sustainable decisions about food and nutrition.
