Many treatment options are available for mixed sleep apnea. It is generally treated the same as obstructive sleep apnea. Your doctor will be able to suggest the option that is best for you. Your doctor may recommend changes to your lifestyle, such as losing weight, not drinking alcohol, not taking certain medications, and not smoking. They may suggest treating your allergies, sleeping in a different position, or wearing an oral appliance at night to help your breathing. Other options may include surgery or CPAP, a device that can keep your airway open while you sleep.
