A monitor on Colette Morris' forearm has reversed her struggle with diabetes. Its constant data feed to her mobile phone teaches her about the foods and stresses that throw her blood sugar out of whack.
The technology isn't for everyone. Four of Morris' siblings have diabetes, and some dislike sensors attached to their arms and false alarms when blood sugar blips.
Old-school finger-stick tests work fine for them, and they still maintain safe A1C blood sugar levels, said the 68-year-old from Minneapolis. "If you're doing all that and your A1Cs are OK, maybe you don't need to know, hour by hour" all of this information.
