Semaglutide (Ozempic) was first tested in 2008 if I'm not mistaken, those trials were for type II diabetes. It was only tested for obesity in 2021.
Its reasonable to expect that any serious side effects would hit you whether you are diabetic or obese. The concern I have is how many people are taking it today for cosmetic or vanity reasons rather than because they are morbidly obese and nothing else has worked.
We do know thanks to trials that it seemed safe and effective when tested on a few thousand people. We don't know what happens when someone takes it for decades, or the rest of their life.
I am absolutely not saying there are known side effects that make it more dangerous than what they put on the box. But it is a new and unknown medication being used by a pretty large population today. More importantly to my original point, those taking it almost certainly didn't read the medical research first so it is an unknown to them.
