[The patient with functional dyspepsia and his/her response to therapy].

We studied during 12 months in the Centro de Especialidades Médicas "Esperanza Macarena" 997 patients with functional dyspepsia (324 males and 673 females) with a mean age of 37.4 and 42.6 years respectively. Patients with any organic disease, including diabetes, were excluded from the study. After completing the study we conclude that patients with functional dyspepsia constitute a large group of patients in gastroenterology clinics, that require multiple diagnostic tests, at great cost and scarce therapeutic successes. Only 36.5 percent of all patients had a good treatment response, most being under 40 years of age and with a relatively high cultural level. Therapeutic response depended on age, sex and social level. The best pharmacological results were obtained with cisapride (10 mg before meals).
