Dr Katharine Owen talks about the different types of diabetes in young adults. There are more forms of diabetes than the commonly known type 1 and type 2. Correct diagnosis of the different forms of diabetes is difficult because of the overlap of symptoms. The implications of incorrect diagnosis are huge, as some forms of diabetes respond better to certain treatments than others. Dr Katherine Owen investigates the different characteristics of monogenic diabetes with the aim of creating systematic diagnostics, and implementing that in clinical care. The ultimate aim is to promote personalised medicine for everybody with diabetes.
