Diabetes management company Dexcom Inc. trounced Wall Street forecasts for the third quarter of 2019, with the company reporting worldwide sales of $396.3 million, up 49% from $266.7 million in the same period of 2018. Dexcom officials attributed the surge to volume growth plus new patient additions as providers and consumers become more aware of the benefits of real-time continuous glucose monitoring (CGM), where Dexcom's G6 has seen steady demand since launching in June 2018.
