Countless cross-sectional surveys of primary and secondary care have demonstrated the ubiquitous nature of medically unexplained symptoms. If grouping diverse symptoms under one heading is appropriate, they account for over half of all new presentations in secondary medical care (Nimnuan et al. 2001a) and a sizeable proportion of ‘frequent attenders’ in secondary care have predominantly medically unexplained symptoms (Fink, 1992a; Reid et al. 2002). Such symptoms are costly, persistent, and associated with significant disability and psychiatric disorder (Reid et al. 2001, 2003), but are generally ignored by mental health services (Bass et al. 2001).
