Rosie Hogg

Specialist Gastroenterology Dietitian

After graduating as a dietitian at the University of Hertfordshire, I worked in a number of specialities within dietetics but gastroenterology has always been my biggest passion.       


Being an IBS sufferer myself, I know the positive impact that both diet and lifestyle factors can have on symptoms and since working as a gastroenterology dietitian, I have gained experience in a wide number of gastrointestinal disorders.     


I specialise in helping clients with dietary and lifestyle advice for gut health, coeliac disease, stoma management, pancreatitis, FODMAP's and 'functional' symptoms such as bloating, wind, reflux, loose stools and constipation. I look forward to working with you!
