Glucose Monitors Can Benefit All Types
I disagree with the negative tone of a recent KHN article about whether continuous glucose monitoring (CGM) helps non-insulin-using people with Type 2 diabetes (Type 2s) (“‘Painless’ Glucose Monitors Pushed Despite Little Evidence They Help Most Diabetes Patients,” March 16).
As a board-certified endocrinologist, I have seen firsthand significant benefits of CGM for people with diabetes, including Type 2s not using insulin. This technology provides useful real-time information about the effects of various foods and activities on glucose levels. CGM also shows how to avoid dangerous hypoglycemia, which can be a side effect of sulfonylurea drugs, frequently prescribed for non-insulin-using Type 2s. Much international research in this population, not mentioned in the article, shows benefits of CGM, including improved A1C levels and decreased hospitalizations and emergency room visits.
While no tool is right for everyone, Type 2s who want to learn about what affects their glucose levels and are willing to use information to change their behavior will often benefit significantly from CGM.
