An implant for obstructive sleep apnea — a serious sleep malady in which breathing stops for 10 seconds to two minutes many times an hour each night — works best in people who are overweight but not severely obese, a new study found.
To qualify for the device, called a hypoglossal nerve stimulator, a person over 18 diagnosed with moderate-to-severe obstructive sleep apnea must be unable to adapt or refuse to wear a continuous positive airway pressure, or CPAP, machine, the gold standard treatment for obstructive sleep apnea.
