      About Dr Cavan

      Dr Cavan promotes self-management and has been closely involved in the development of education programmes for people with diabetes. He is also author of successful books on self-management diabetes.

      For many years, he worked as a Consultant at the Bournemouth Diabetes and Endocrine Centre, one of the leading NHS diabetes centres in the UK. He was also a previous Chair of the Education and Psychosocial Care Section of Diabetes UK.

      In 2013, he left the UK to work for three years as the Director of Policy and Programmes at the International Diabetes Federation (IDF) in Brussels. There he was responsible for overseeing a range of programmes that addressed the various needs of people with diabetes at a global level.

      In 2014 he published his first book, ‘Reverse your diabetes: the step-by-step plan to take control of type 2 diabetes’, aimed at providing people with type 2 diabetes with the information they need to make lifestyle changes to achieve better control of their condition, and possibly to reverse it. In 2018 he published ‘Take control of type 1 diabetes’ and, together with Emma Porter, who has type 1 diabetes, ‘The low carb diabetes cookbook’. His latest book, ‘Busting the diabetes myth’, published in 2022 provides fully up to date advice on how to reverse type 2 diabetes and prediabetes.

      In addition to his clinics at London Medical, he is a part time consultant at University Hospitals Dorset (Bournemouth and Poole). He also works internationally on diabetes projects (currently in Bermuda and Africa) and trains health professionals in diabetes management.
