What Makes the Libre 3 Plus Different From a Regular Sensor
The libre 3 plus sensor is Abbott's smallest CGM sensor to date, roughly the size of two stacked pennies, and it wears on the back of the upper arm for up to 15 days. What most articles skip is the actual mechanical reason this matters: fewer adhesive changes mean fewer skin irritation complaints, which is one of the top reasons people abandon CGM therapy within the first three months, according to adherence studies published by diabetes technology researchers. A 15-day cycle also means only six sensors are needed for a full 90-day quarter, a detail that changes how you budget supplies with your pharmacy or DME provider.
