Sleep apnea is a common sleep disorder where you stop breathing repeatedly during sleep. This can leave you feeling tired during the day and increase your risk for heart disease and other serious health problems. Continuous positive airway pressure (CPAP) has been the main treatment since the 1980s. It involves wearing a mask connected to a machine that keeps your airways open with gentle air pressure. However, about 50% of people stop using CPAP within the first year because they find it uncomfortable. Other options include bilevel positive airway pressure (BPAP) devices and surgical implants like Inspire, which stimulates the hypoglossal nerve to keep the airway open. Researchers are also developing new treatments and portable monitoring tools for at-home sleep studies. Women, especially after menopause, are almost as likely as men to have sleep apnea, although their symptoms may differ. Treating sleep apnea can help prevent dementia and heart disease. New surgical methods and devices like eXciteOSA, which uses mild electrical pulses to stimulate tongue muscles, are also being explored. Weight loss can also improve sleep apnea symptoms by reducing fat in the tongue and muscles around the airway.
