From mobihealthnews, ABI Research predicts that by 2017, there will be 170 million wearable and wireless health and fitness devices in the US. While I assume they include CGM (continuous glucose monitor) in these numbers, having more people with diabetes wearing devices like the Jawbone Up or the Fitbit is likely to happen. The real win will occur when the data from these devices gets truly integrated with glucose data and insulin data to help make future management decisions. If all the data stays in silos, it’s unlikely to be of much benefit.
