OSA? Put Your Tongue on a Diet

“Most clinicians, and even experts in the sleep apnea world, have not typically focused on fat in the tongue for treating sleep apnea,” said Richard Schwab, MD, chief of Sleep Medicine. “Now that we know tongue fat is a risk factor and that sleep apnea improves when tongue fat is reduced, we have established a unique therapeutic target that we’ve never had before.”

From the research article abstract:

Conclusions:

Weight loss reduced volumes of several UA soft tissues in persons with obesity and OSA. Improved AHI with weight loss was mediated by reductions in tongue fat. New treatments that reduce tongue fat should be considered for patients with OSA.
