Typically, people with learning difficulties due to intellectual disability face a variety of daily challenges, and require continual support from specialized carers. If they are affected by a chronic medical condition, such as diabetes, people with intellectual disability require coordinated support from diabetes-aware carers and informed healthcare providers. The authors examine the challenges faced by people with intellectual disability, offer advice to carers and healthcare providers, and describe a web-based resource designed to enhance such a collaborative approach to diabetes care and management.
