Obstructive sleep apnea occurs as repetitive episodes of complete or partial upper airway blockage during sleep. During an apneic episode, the diaphragm and chest muscles work harder as the pressure increases to open the airway. Breathing usually resumes with a loud gasp or body jerk. These episodes can interfere with sound sleep, reduce the flow of oxygen to vital organs and cause heart rhythm irregularities.

 

Common obstructive sleep apnea warning signs include:

• Daytime sleepiness or fatigue

• Dry mouth or sore throat when you wake up

• Headaches in the morning

• Trouble concentrating, forgetfulness, depression or crankiness

• Night sweats

• Restlessness during sleep

• Problems with sex, like a low sex drive

• Snoring

• Waking up suddenly and feeling like you're gasping or choking

• Trouble getting up in the mornings

• Waking up often in the middle of the night to pee

• High blood pressure

• Gastroesophageal reflux disease (GERD)
