I felt a special kind of awe, then panic, watching my glucose levels skyrocket for the first time after relishing a cold beer on a sweltering summer evening. It was a biological push notification from the fluid just beneath my skin that the carbohydrate-packed beverage was interfering with efforts to maintain my health and weight.
For years, people with Type 1 diabetes have worn continuous glucose monitors, or CGMs, to track blood sugar spikes and make sure they’re getting enough insulin. CGMs are small patches with tiny needles for sensors that prick the skin and are generally worn on the stomach or back of the arm.
Now, a wave of tech companies are selling CGMs to the public. That made me curious: Would this work for me? What would I learn?
