The Welsh Government says its diabetes strategy is working to deliver better healthcare for those with the condition, as well as focusing on the need for improved education.
It comes after a report by charity Diabetes UK Cymru said millions of pounds spent caring for people in Wales with diabetes isn't being used effectively.
A Welsh Government spokesperson said: “The Together for Health - Diabetes Delivery Plan, which was launched in September 2013, puts patient awareness and support at the heart of the Welsh Government’s diabetes strategy.
“A key element is the introduction of a diabetes patient management system, which will allow clinicians to deliver better healthcare for people with diabetes.
"The plan also focuses on the need for education about diabetes so patients are fully involved in their care and able to contribute to the development of their personalised care plans.
“Health boards and NHS trusts have also developed their own plans to prevent diabetes and reduce the risk of long-term diabetic complications for their populations.”
