It started with a donut. One morning in her 20s, Jessie Inchauspé says, she grabbed her usual sugary breakfast on her way to work in Silicon Valley - and noticed something strange. Her new fitness tracker showed her blood sugar spiking, then crashing. The pattern mirrored her bouts of brain fog, anxiety, and exhaustion, she said. "It might seem obvious today that what we eat impacts our mental health, but back then, for me, I hadn't connected the dots," Inchauspé told Business Insider.
Founded in 1999, Dexcom has become a leading developer of the continuous glucose monitor. For people with diabetes, wearing a glucose monitor eliminates the need for fingerstick tests and allows their blood sugar levels to be tracked around the clock. When a patient's blood sugar shifts dangerously, Dexcom will alert them. Initially, the company's products primarily served people with Type 1 diabetes, an autoimmune disease that typically develops in adolescence. Over time, its research expanded to include those with Type 2 diabetes as well.
