[Persistent diarrhea].

Abstract

In this article the current concepts on persistent diarrhoea are reviewed. Persistent diarrhoea is important because its aetiology is unclear, is difficult to treat, affects the nutritional status and increases the risk of death. The identification of risk factors for persistent diarrhoea is important because it can obtain valuable information relative to the pathogenesis and prevention of this disease. The concepts of diarrhoea and risk factors are also reviewed. In addition we explore the methods of management and treatment of patients with persistent diarrhoea.
