Answer: CPAP is the least invasive way to treat obstructive sleep apnea (OSA). Other options are a UPPP procedure that involves having the uvula and tonsils surgically removed, weight loss, and/or a dental device that would help keep the tongue out of the airway.The UPPP surgery has been described by one of instructors who had it as 'swallowing razor blades for six months'. I don't think that's a recommendation. He said that he lost a lot of weight because he could only eat ice chips for a long time. He ended-up back on a CPAP machine anyways. The UPPP has a success rate of like 25%.Weight loss may or may not help your OSA. If anything, it won't make it worse. Some people who are at their perfect weight have OSA.I recommend that you accept the OSA and use your machine as prescribed by your doctor. Your quality and length of life will likely be much better. A diagnosis of OSA should only be made after a sleep study confirms it. If that has been done, then you very likely do have OSA.
