Please, no. GLP1s leave you worse off than when you started if you stop taking them. Weight is also not necessarily the factor that leads to sleep apnea; I got diagnosed while having a healthy weight in my 30s.
Something I'd picked up somewhere a decade or two ago was losing weight too fast can cause problems with bone and muscle density. So it could be related but not a direct effect.
I think they were referring to rebound weight though, something else I'd heard about these drugs that also doesn't affect everyone. A scarier one was one person whose weight got too low so they stopped taking it, but for some reason had a lot of trouble gaining any weight and getting up to a healthy level.
This doesn't seem factual, or at the very least, not that simple?
