Sleep apnea is a condition in which the flow of air pauses during breathing while you sleep because the airway has become blocked. Relaxation of the muscles in the upper throat in people who have a narrow airway can result in a blocked airway. Common symptoms include:
Loud snoring, followed by a long silent period (apnea), then a loud snort or gasp which is followed by breathing or snoring
Frequent urination at night
Depression that worsens
Feeling sleepy or falling asleep inappropriately during the day, such as while driving or during conversation
Difficulty concentrating, forgetfulness or irritability
Loss of interest in sex
Poor school or work performance
In children, hyperactive behavior may occur
Disturbed sleep of bed partner
Because people who have sleep apnea are asleep when some symptoms occur, they are often not aware of the periods of not breathing (apnea). Often it is the bed partner or a family member who witnesses the apnea.
How is sleep apnea diagnosed? Your physician will perform a complete medical history and physical exam. You may be given a survey to complete asking about daytime sleepiness, sleep quality and bedtime habits. A sleep study (polysomnogram) is used to confirm sleep apnea and this is performed in a Sleep Disorders Center. In certain instances, a sleep study may be done with a portable system you can take home and then return to the Sleep Center the following day.
