> it can often resolve when the surgery is "fixed" (e.g., removing lap-bands) If the ailment is exclusively psychological, then presumably you believe this would hold even for a sham surgical intervention.

Otherwise it sounds like a mixture of physical and psychological, and you are being overly reductive.
