A new study points to a surprising new culprit in sleep apnea: tongue fat.
OSA is common -- affecting an estimated 25 million Americans, according to the American Academy of Sleep Medicine. While it can affect people at any weight, obesity raises the risk.
To see whether trimmer tongues might be one, his team studied 67 OSA patients who were obese and went through a weight-loss program -- with either surgery or lifestyle changes alone. But MRI images done before and after the weight loss revealed some finer details: There was a direct correlation between loss of tongue fat and patients' symptom improvement.People who lost weight also showed reductions in certain jaw and airway muscles -- and those changes, too, seemed to improve apnea symptoms. But tongue fat was a more important factor.American Journal of Respiratory and Critical Care Medicine.
"This shouldn't take away from the importance of overall weight loss," Abbott said. Not only will it ease apnea symptoms, she noted, but it should also be a boon to a person's general health. He also noted that certain upper-airway exercises can improve sleep apnea -- which he said raises the question, does tongue fat change when you do these exercises?
