In yesteryear, a lot of doctors resented a patient that was well informed as if threatened by it. But in today's world with so much information readily available to us (just use credible sources), I think doctors expect patients to become informed about their own conditions. The doctor has to do less explaining and isn't looking at a patient with a blank stare.

Also, no one has more time to dedicate to researching my health conditions than I do. A doctor's time is limited so help them out by asking informed questions.
