To be fair, most people probably are hypochondriacs. Somehow we have come to expect that all our nagging ailments should be fully treatable by either a pill or a surgery. In reality, human body is pretty good at self-repairing and self-regulating and modern medicine can help it only in certain clear cut cases. Medicine is just not that good and the doctors know it.
I'm certain in the sample of patients most GPs see, hypochondriacs are overrepresented, but that really does not in any way eliminate the problems I experience, so from my point of view it's still a real concern.
