Unexplained IllnessUnexplained Illness
How can it be explained? How can I be a good doctor
when I can’t explain my patient’s symptoms?
What is the evidence for effective management?

46 y/o woman from LaCrosse comes self-referred, as a new patient for the evaluation of multiple waxing and waning symptoms for more than 15 years. She comes with two bulging radiology folders and a 3 inch stack of medical records recording many normal physical exams and laboratory tests. She comes to the “U” to find out what’s wrong; “something is definitely wrong” and the other doctors “think it’s all in my head”. She is not worried about a specific condition.
PMH = lots of illness; no disease. FH = not significant.
Soc Hx = married twice, two young adult children, insurance office manager, “rough childhood”.
ROS = very +, see following slide. PE = She looks healthy and worried. VS and full PE normal.
Labs and Imaging = lots of them all normal

Impact on Health Impact on Health ServicesServices
60% of primary care patients recurrently present with unexplained somatic sx. “ … the failure to provide mental health service [had] the potential of bankrupting the health care financing system due to over-utilization of primary care physicians by somatizing patients.”
