According to medical guidelines counselling on sports and physical activity should be part of diabetes treatment. Using an online questionnaire (n = 181), we explored how people with both type 1 and type 2 diabetes experienced this counselling in the Netherlands. Most respondents were critical, indicating that they did not receive proper guidance or helpful advices. A third of the respondents mentioned that there was hardly any attention for the subject during their treatment. This conflict between guidelines and experiences point towards the need for more insight in critical issues in counselling regarding taking up sports and physical activity (again) after diagnosis.
