Abstract
Diabetes is a complex metabolic disorder that is increasing in incidence globally. It is the most common non-communicable disease worldwide. Diabetic patients pose a challenge to anaesthesia and surgery due to the organs and systems affected by the disease. Good glycaemic control perioperatively is essential to minimize complications. There is an increasing number of therapies to control diabetes, and this is rapidly evolving, so a multidisciplinary approach to the management of these patients is recommended, and increasingly the patients themselves should be participating in managing their diabetes as long as possible.
