It's triage. If you appear to be fit there's no reason to suspect anything bigger lurking. General rule in hospitals here is sending you on your way again as quickly as possible, if you are mobile/young/fit. If it's serious you'll be back. I'm guessing we're going to see a major shift in medical treatment of fats over the next 10 years. If the fats think health professionals are fatphobic now, it's going to get way, way worse for them, once the costs are all added up and society decides to not put up with their bullshit and endangering normal people's lives anymore. Think of fat truckers, the stories in this thread or the boy who is missing his head because of fats.
