Continuous Glucose Monitoring in a Patient With Insulin-Treated Type 2 Diabetes

PRESENTATION J.B. is a 45-year-old white man with a medical history notable for type 2 diabetes for 12 years, dyslipidemia, coronary artery disease (status post-myocardial infarction [MI] and left anterior descending [LAD] stent placement in 2004), chronic sinus disease, and sleep apnea. Postprandial blood glucose levels often are not part of the testing regimen, and many patients do not understand how to adjust their insulin or oral medications based on the content of their meals. CLINICAL PEARLS * Allowing patients with type 2 diabetes to see their blood glucose levels in real time and understand the interrelated effects of diet, exercise, and stress on their blood glucose levels can have a major positive effect on their glycémie control. * Wearing an RT-CGM device can guide food choices and insulin doses as they relate to carbohydrates and the glycémie index of foods. * Patients with longstanding type 2 diabetes may become more engaged and take ownership of their diabetes after wearing an RT-CGM device.
