[A difficult diagnosis: dyspepsia].

Painful epigastric syndrome where gastroenteric or extra-digestive lesions are not revealed by common investigatory techniques (x-rays, endoscopy) are often diagnosed as primary or functional dyspepsia. This review is important because about half of the sufferers complain of functional gastroenteric disorders. The term "Dyspepsia" is reviewed on the basis of old and more recent literature together with long personal experience. The overall results confirm the existence of Dyspepsia as a separate complaint in its own right. The importance of Dyspepsia should be fully understood since a correct diagnosis avoids the need of further checks and choice of pharmaceutical treatment is made easier. Support psychotherapy and diet revision are also facilitated.
