Over a million people in the Netherlands have diabetes, and 90% of them have type 2. Every year 1,200 more people are diagnosed with the disease. In order to stay healthy, these people need to constantly make sure that their blood sugar levels stay low and stable. They also have to follow a low-sugar diet and get enough exercise. ‘Diameter’, a smart, app-based system developed by the UT and ZGT Hospital Group Twente (Ziekenhuisgroep Twente), makes the task a lot easier – and in many cases even helps patients cut back on medication.
