According to a 2014 study by the Center for Disease Control, 29.1 million Americans -- 9.3 percent of the national population -- have diabetes. Particularly for those with Type 1 diabetes, keeping a close eye on blood glucose levels is key for avoiding life-threatening highs and lows. DexCom, makers of blood glucose monitors that take a reading every five minutes, is said to be developing a new Apple Watch app to interface with its monitors, expected to be ready when it becomes available in April.
