A new study suggests that a weight loss drug could be the first effective medication for treating sleep apnea, a condition that affects millions and can lead to serious health problems. The drug, called tirzepatide, is already approved for weight loss and type 2 diabetes, and is sold under the brand names Zepbound and Mounjaro. While weight loss has long been recommended as a way to reduce the severity of sleep apnea, many people struggle to lose weight through diet and exercise alone. This new drug could offer a game-changer for those struggling with sleep apnea.
