The best treatment for both obesity and sleep apnea is weight loss. Weight loss strategies are generally not very successful and since 75% of obese children will become obese adults, urgent treatments are needed to reduce heart disease in the long-term. Treating sleep apnea in obese children may be one of the ways to reduce heart disease. Sleep apnea can be treated with continuous positive airway pressure (CPAP), which involves wearing a mask attached to a breathing machine while asleep. It is unknown how effective CPAP is in reducing heart disease in obese children.
