Sleep Disorders in Type 2 Diabetes.

Type 2 diabetes mellitus (T2DM) has shown to be associated with higher incidence of sleep disorders, which may be due to disease itself or because of secondary complications or associated comorbidities associated with diabetes. On the other hand, shorter sleep duration and erratic sleep behavior itself have been linked with higher incidence of obesity, metabolic syndrome, and T2DM. Assessment of sleep quality and sleep disorders as a part of the comprehensive medical evaluation is recommended based on emerging evidence suggesting a relationship between sleep quality and glycemic control in persons with T2DM. In this review, we attempt to summarize common sleep disorders associated with T2DM, their impacts on glycemic and other metabolic control, and various preventive and therapeutic strategies to tackle these problems.
