CPAP is 800CAD here (though only about 200 after insurance) and dental appliances are even more expensive and not covered by insurance. Anecdata: I know that going over a certain weight triggers apnea and snoring for me so I try to stay under it - less expensive, less intrusive, better for the health overall. Research like this is both interesting and important to me. It is not about fat-shaming, it is about knowing the options. I understand that there are people for whom weight loss mai not be attainable or maintainable but it certainly will help to a great number of people.
