Donnay created DG Dietetics as her private practice towards the end of 2015. It is currently running as a part-time business, since Donnay also works as a dietitian elsewhere, seeing both hospital patients as well as outpatients. Clients may self-refer for dietetic advice, and Donnay also receives referrals from medical practitioners. She can offer dietary advice for a broad range of medical conditions, including but not limited to: irritable bowel syndrome (IBS), cancer, insulin resistance, diabetes, high cholesterol, liver disease, arthritic conditions, malnutrition. Donnay enjoys advising clients on healthy eating for weight management to assist them in achieving and living a healthy life.
Donnay is also accredited to do Vitality nutrition assessments for those on the Discovery Vitality programme.
