There are many ways of treating the symptoms of sleep apnea. This may include conservative approaches, such as a new sleeping position or the use of an oral appliance. If your apnea symptoms are severe or conservative treatments are not working, you may be prescribed a continuous positive airway pressure device (CPAP) to open the airway. In severe cases, surgery may be necessary. Keep in mind that a diagnosis of sleep apnea is not always permanent. Many patients find that losing weight can be an effective way of opening the airway during sleep.
