Living and Wellness Exhausted? You Might have Sleep Apnea By Sleep Medicine, January 2, 2014 At UPMC’s Sleep Medicine Center, doctors can diagnose and treat sleep apnea, often with surprisingly fast results. Sleep Apnea Diagnosis Patient Story Overweight and diagnosed with high blood pressure, diabetes, and an irregular heartbeat, Robert Guthrie underwent a sleep study at UPMC’s Sleep Medicine Center to evaluate his pulmonary function and suitability for gastric bypass surgery. He was shocked to discover he had sleep apnea so severe he actually stopped breathing 147 times per hour. Affecting 12 million Americans, sleep apnea doesn’t just disrupt sleep. Untreated, it can cause serious health problems and lead to deadly accidents due to exhaustion. “I was totally clueless. It was serendipity that took me to a sleep expert, and it probably saved my life,” says Robert, 65, who immediately began using a nighttime breathing apparatus known as a continuous positive airway pressure (CPAP) machine. Within a week, he was sleeping soundly for the first time in six years. “It was life changing,” says the Hopwood, Pa., resident. “I feel 20 years younger.” What Happens While Sleep Apnea Patients Slumber? Most people don’t know they have obstructive sleep apnea, usually caused when the soft tissue in the back of the throat collapses during sleep. People with sleep apnea stop breathing repeatedly. With each interruption, the drop in oxygen levels prompts the brain to send a surge of adrenaline to kick-start breathing, which also leads to a spike in blood pressure. “This can happen 600 times a night. It’s a burden on the cardiovascular system and affects the quality of sleep,” says Patrick J. Strollo Jr., MD, medical director of the UPMC Sleep Medicine Center. According to Dr. Strollo, if you snore loudly, wake up exhausted despite a “good night’s sleep,” or feel tired or sleepy during the day, you should talk to your primary care physician. Since sleep apnea cannot be detected while you’re awake, your doctor may ask you to participate in an overnight sleep study. At UPMC’s Sleep Medicine Center, patients stay in a private bedroom where a sleep technician applies sensors that measure breathing, heart rate, brain activity, and other body functions during sleep. A team of specialists diagnose sleep apnea by looking at the test results and reviewing medical history. Treatment options may include a CPAP machine like Robert uses, which blows air through a special mask worn over the nose. “I wasn’t wild about wearing the mask. But staying on it was a no-brainer — it’s worth it for a good night’s sleep,” says Robert. Learn more about the UPMC Sleep Medicine Center.
