would have found the PCOS if you eliminated the obesity option  This is a great point, one the my-doctor-is-a-fatshamer crowd can't seem to get. Car mechanics don't always know what's making your engine run rough. Sometimes you gotta fix a few things and see if it gets better. Computer techs don't always know why your PC keeps crashing - sometimes you just gotta keep poking at it until the crashing stops. I could go on. Why do they expect doctors to be magicians. If you present to your doctor with breathing problems, weigh 400lbs, and have nothing else obviously wrong, it's time to fix the elephant in the room (literally) and see if things improve. In any other field, this would be common sense. If your car is running sluggish and your air filter is dirty, you can bet you're getting a new air filter. The real reason they rage at their doctors, but not their car mechanics, is because they don't want a diagnosis - they want an excuse.
