In obstructive sleep apnea, the tongue or throat tissue blocks the airway. This causes the person to briefly stop breathing many times a night. Sleep apnea also appears to raise the risk of cardiovascular problems. Therapies that help keep airways open during sleep, such as continuous positive airway pressure (CPAP), can improve quality of life and lower cardiovascular risks. (Locked) More »
