In this episode, host Alyssa Watson, DVM, welcomes back Thomas Schermerhorn, VMD, DACVIM, to talk about his recent Clinician’s Brief article, “Application & Use of a Continuous Glucose Monitor in Cats & Dogs.” Dr. Schermerhorn reviews the science behind continuous glucose monitoring, a true game changer in managing diabetic pets, and how it improves our ability to effectively adjust insulin dosing. He also talks about some practical limitations, including what challenges you need to expect (eg, sensors falling off, after-hours alarms, etc.).

Key Takeaways
Continuous glucose monitoring (CGM) obtains a glucose curve based on minute-by-minute interstitial glucose data for up to a ~2 week period.
CGM sensors, which penetrate the skin with a filament, are obtained using a prescription, and the sensors can pair with a compatible reader and/or a smart phone app.
These sensors are intended to adhere in place for up to 2 weeks on humans—animals may require extra steps to prevent dislodging, eg, fur clipping, extra tissue glue, prevent scratching, etc.
CGM data shows the dynamic response to insulin, rather than an average like fructosamine or A1C, and isn’t impacted by the confounders of traditional in-office (or even at-home) glucose curves that rely on repeated venipuncture.
With units having built-in alarms, clients must be counseled that periods of hyperglycemia are to be expected, whereas there should be a plan of action for hypoglycemia.
