A new study finds there could be thousands of Americans suffering from a sleep disorder they don't even know they have.
The study from the Centers for Disease Control and Prevention looked at 6,500 residents of Georgia from metropolitan, suburban and rural areas of the state. 16 percent said they had persistent problems staying awake during the day, 31 percent said they can't sleep through the night and 25 percent reported having trouble falling asleep. However, only 10 percent had been diagnosed with a sleep disorder.
It's a concerning statistic because untreated sleep disorders can cause illnesses like diabetes, stroke and obesity.
