Functional Dyspepsia - Effect of Acid-Reducing Treatment and Information.

Plain-language summary

Study title: Functional dyspepsia -- effect of acid reducing treatment and individualized information. Summary: 15-20% of all people experience dyspepsia each year. Dyspepsia means pain or discomfort in the upper part of the abdomen. Accompanying symptoms from the esophagus may be present. The most important relevant medical examination is gastroscopy, and if the findings are normal the condition is usually classified as functional dyspepsia. Several disturbances of function are now known as potential causes of such symptoms, and the optimal choice of treatment may vary. In the study the investigators plan to examine whether different types of functional disturbances respond differently to medical therapy. In particular, the investigators want to assess whether comprehensive and individualized information will influence the results of therapy. This has not been previously studied systematically. The investigators also postulate that disturbances of function of the esophagus may cause complaints that should be classified as functional dyspepsia even if the symptoms are atypical. Few studies have been done to evaluate this hypothesis, and there may be potential consequences for choice of appropriate treatment. In animal models and in humans is recently demonstrated that elevated gastric pH because of anti-ulcer treatment can trigger food allergy. We use a proton pump inhibitor in our study and eventually development of food allergy will influence patient's condition in an observations period. That why we're observing IgE dynamics in our study.
