More than a minor annoyance, snoring can be a sign of something more serious: obstructive sleep apnea. This disorder, marked by breathing that is interrupted during sleep, can cause blood pressure to skyrocket.
More than 18 million Americans adults have sleep apnea, which increases the risk of heart disease. People who are overweight or obese are at higher risk for sleep apnea, but slim people can have it too. If you snore and often wake up feeling tired, talk with your doctor; there are easy ways to screen for apnea, says Dr. Robert Ostfeld, associate professor of clinical medicine at Montefiore Medical Center in New York City.
