[Epidemiology, classification and management of functional dyspepsia].

Functional dyspepsia belongs to functional disorders of the gastrointestinal tract. Its prevalence is estimated up to 25% of adult population of Western countries. On the contrary to irritable bowel syndrome, functional dyspepsia is slightly more frequent in men. The recent classification of functional dyspepsia includes its two subcategories: postprandial distress syndrome (DS, B1a) and epigastric pain syndrome (EPS, B1b). In the management of functional dyspepsia three strategies are taken into the consideration: 1. early gastroscopy performed in people over 45 years of age and independent of age in case of alarm symptoms. 2. Therapy based on noninvasive H. pylori testing: in young adults with dyspeptic symptoms, without alarm symptoms and not treated with nonsteroid antiphlogistic medications. 3. Empiric treatment: considered as an initial therapy in patients not diagnosed with dyspepsia, without alarm symptoms and in dyspeptic patients despite H. pylori eradication. In the treatment of functional dyspepsia the following treatments are applied: dietary treatment, farmacotherapy with antisecretory drugs, prokinetics, H. pylori eradication, antidepressants and psychotherapy. Directions of the further investigation in functional dyspepsia include: improvement of endoscopic methods, and searching for new groups of medications according to the new Rome III classification of functional dyspepsia, based on its pathophysiology.
