Dietician and Breath Testing

Sarah Mercer


I am a New Zealand Registered Dietitian, having graduated from the University of Otago in 2008.  I have been involved with the breath testing since its inception in 2013.  I consult each patient following their breath tests and together work out a diet plan that best suits them.  I also work at Waikato Hospital and have done so since graduating, specialising in gastroenterology and surgical nutrition. 


I have a keen interest in helping people with irritable bowel syndrome and other gastrointestinal problems.  I love a challenge and enjoy assisting people to modify their diets to improve their quality of life.
