#433 CGMs, Insulin, and How to Adjust Diabetes Meds to Glucose Patterns

74 min • 1 april 2024

Step up your diabetes game! Learn the ins and outs of continuous glucose monitors (CGM) including key features, what and how to order, interpreting CGM data (time in range, time above range, etc.), and how to make adjustments to a patient’s insulin regimen, aka “insulin pattern matching”. We discuss common scenarios including overnight hypoglycemia, exercise-induced hypoglycemia, post-prandial hyperglycemia, what to do when the patient runs high all the time, and how to incorporate GLP1 agonists and SGLT2 inhibitors into a patient's regimen. Returning guest and Paul’s favorite frenemy, Dr. Jeff Colburn (VCU Health) returns!
