Tongue fat? Lose weight and lose tongue fat? A recent study had an interesting finding - overweight people who lost weight improved their sleep apnea symptoms because they also lost fat in their tongues.
It makes sense - obesity is the primary risk factor for developing sleep apnea, and losing weight improves sleep apnea symptoms. In the Univ. of Pennsylvania study, weight loss also resulted in reducing the volume of some soft tissues of the upper airway (pterygoid and pharyngeal lateral wall), which also improved sleep apnea. But loss of tongue fat was the most important reason for sleep apnea improvements.
