Not necessarily.
Sleep apnea generally doesn’t just go away without treatment unless you resolve what is causing the problem. For example, if your sleep apnea is caused by being overweight and you achieve a healthy weight then you may no longer have sleep apnea and therefore will no longer need treatment.
However, not all cases of sleep apnea are correctable. Sometimes sleep apnea is caused by things outside our control such as the shape or size of the tongue, jaw, and airway. Sometimes these things can be corrected with surgery and sometimes they can’t.
In instances where lifestyle changes aren’t enough to cure your sleep apnea, then continued treatment is necessary for your health. However, there are other treatment options available for those who do not tolerate CPAP therapy well. The primary alternative is the use of a custom oral appliance.
