Diabetes management following stroke

Introduction to diabetes

To diagnose diabetes accurately one needs to understand the glucose levels that are associated with impaired glucose tolerance and diabetes as shown in these two diagrams:

A single random glucose

A fasting glucose

A single random glucose is an unreliable diagnostic test but glucose > 11.1 mmol/l suggests diabetes.

A fasting glucose is usually required to confirm the diagnosis.
