Gastroparesis is a serious, life-threatening side effect.
It occurs in a small number of patients, sure, but maybe that just means I am more risk averse than you. My calculus is simple. I don't need wegovy. I can lose (and am losing) weight without it. Sure, it would be easier with wegovy, but it is not necessary. I am not going to take an unnecessary drug that has a nonzero chance of killing me.
Excellent! A huge chunk of people try and fail to do this for a wide variety of reasons.
If you can lose weight without the help of a GLP-1 drug, then yeah, that is likely the safest option. But most people aren't choosing between using a GLP-1 drug to lose weight or losing weight without it - they're choosing between staying fat and using the GLP-1.
This adds literally zero information.
