The best method for dealing with a brusque doctor is speaking up, according to Dr. Charles Yeo, a general surgeon at Johns Hopkins Hospital. If you feel a doctor has been too rushed with you, or hasn't answered your questions satisfactorily, tell him so.
"Most doctors would slow down if you tell them you need more time," said Dr. Yeo. "Most of us are interested in keeping our patients; most of us like our patients."
It's also a good idea to write down your questions before seeing the doctor, so none of them slip your mind in the midst of the consultation.
