About 70 percent of people with obstructive sleep apnea are overweight or obese. Their health care professionals usually encourage them to lose weight.

Surprisingly, there have been few formal studies of how effectively weight loss leads to lesser, lighter snoring and diminished incidents of apnea and hypopnea during sleep. Despite this, anecdotally practitioners report striking improvements in both OSA and snoring among patients who lose weight.

The challenge that confronts the surgeon is determining what part of the upper airway is causing the obstruction to airflow. There are many possible sites, and conventional sleep testing does not identify the area the surgeon should modify. If the surgeon does not treat that site in the airway, or if there are multiple sites of obstruction, it is unlikely that the sleep apnea will diminish to a degree that eliminates the need for other treatment.
! [2 R# h) [% X/ b/ O# E, b& X8 t$ H# Z( ~% c8 C p
Given the several sites where airway obstruction may exist, there are several types of operations currently used to treat sleep apnea. The most common is uvulopalatopharyngoplasty, or UPPP. The success rate of this operation is about 50 percent. Some surgeons have achieved very high success rates using multiple, staged operations.2 Nonetheless, most authorities recommend routine re-assessment for sleep apnea after surgery. See the caution below. There's more about surgery here.4 c- R9 f- m( Y |8 p

The appliance is worn in the mouth during sleep. Most appliances work by positioning the lower jaw slightly forward of its usual rest position. This small change is, in many people, enough to keep the airway open during sleep.

You can simulate the effect of an oral appliance with a simple experiment. If you make a snoring sound right now and, in the middle of it, thrust your jaw forward, you will see that the snoring sound stops.

The mask, worn snugly over the nose, or sometimes nose and mouth, during sleep, supplies pressurized air that flows continuously or intermittently into the sleeper's throat. The increased air pressure prevents the sleeper's airway from collapsing.

The pressurized air is supplied through a flexible tube from one of several types of machines: CPAP (continuous positive airway pressure), BiPAP (bilevel positive airway pressure), VPAP (variable positive airway pressure), and so on. Studies of the effect of PAP therapy show that OSA patients who consistently use their machines feel better and, as a result of the reduction of apnea and hypopnea episodes during sleep, encounter fewer complications of the disease.
