I wouldnt jump to conclusions too fast. I'm a very thin person, but I get a lot of ads for GLP-1. My doctors have always said I need to gain weight, so I can assure you I'm not searching for weight loss solutions. Nor am I diabetic.
GLP-1 drugs are such money makers that it's worth advertising them so that you 1) know they exist 2) might recommend them 3) might take them yourself at some point.
A month's supply of Wegovy/etc costs nearly $2k.
Same thing with the monoclonal antibody drugs, you can be looking at tens of thousands of dollars per month for a single patient.
You also see this with luxury brands, that advertise to segments that cannot afford their products, in order to build image of luxury and prestige.
That said, I asked my friends/family if they had <not embarrassing or too intrusive> condition, and more often than not, someone in the household had it.
To be fair, for GLP-1 drugs I see enough of them in untargeted ads (eg. billboards) that I just assume they're carpetbombing everyone rather than doing precise targeting.
