One of the tools that I’ve gotten more interested in the past few years are Continuous Glucose Monitors (aka CGMs). These are patches that can be painlessly applied to the arm and that sync to an app on your phone, providing continuous information about your glucose levels. While they are not 100% accurate, they are close enough to more traditional methods for checking glucose (e.g. fingerstick) to give a pretty close estimate of your blood glucose at any particular moment, and since they can provide hundreds or even thousands of data points per day, can be used to track trends and see patterns.
