The nonsurgical treatments for obstructive sleep apnea include behavior therapy, including weight loss, medications, dental appliances, continuous positive airway pressure, bi-level positive airway pressure, and auto-titrating continuous positive airway pressure.
Sleep apnea is treated with lifestyle changes, mouthpieces, breathing devices, and surgery. Medicines typically aren't used to treat the condition. Treatment may improve other medical problems linked to sleep apnea, such as high blood pressure. Treatment also can reduce your risk for heart disease, stroke, and diabetes.
