Imagin very night while you're asleep, you stop breathing. Not just once, but hundreds of times throughout the night your breathing is interrupted. Your airway becomes blocked, causing you to gasp for a much needed breath. It's hard to imagine, but millions of people suffer from this condition, called Obstructive Sleep Apnea. Sleep apnea is a condition in which your breathing stops during sleep due to a collapsing airway. These persistant breathing obstructions can severely disrupt your sleep patterns and cause excessive sleepiness or fatigue during the day. But that's not all. Sleep apnea has been associated with hypertension, heart failure, stroke, and diabetes. Even harder to imagine is the fact that many people suffering from sleep apnea don't even know they have it. The standard method to determine if someone suffers from sleep apnea is a sleep study. This is a simple diagnostic test that monitors your breathing, oxygen level, and other vital data while you sleep.
