The doctor-patient relationship is ideally an intimate partnership where information is exchanged openly and honestly. That is seldom the reality, however. Deception in the doctor-patient relationship is more common than we'd like to believe. Deception is a charged word. It encapsulates precisely what we dread most in a doctor-patient relationship, and yet it is there in medicine, and it often runs both ways. I once took care of a young woman who told me she suffered from a rare blood disorder that caused clots to develop in her heart and lungs.
