Dyspepsia (indigestion) facts
- Dyspepsia is a functional disease in which the gastrointestinal organs, primarily the stomach and first part of the small intestine, function abnormally. It is a chronic disease in which the symptoms fluctuate in frequency and intensity.
- Theories of the cause of dyspepsia include abnormal input from intestinal sensory nerves, abnormal processing of input from the sensory nerves, and abnormal stimulation of the intestines by motor nerves.
- The primary symptoms of dyspepsia are upper abdominal pain, belching, nausea, vomiting, abdominal bloating, early satiety, and abdominal distention (swelling). The symptoms most often are provoked by eating.
- Dyspepsia is diagnosed on the basis of typical symptoms and the absence of other gastrointestinal diseases, particularly acid-related diseases and non-gastrointestinal diseases that might give rise to the symptoms.
- Testing in dyspepsia is directed primarily at excluding the presence of other gastrointestinal diseases and non-gastrointestinal diseases. Some patients may require specific testing of certain gastrointestinal functions.
- Treatment in dyspepsia is primarily with education as well as smooth muscle relaxant and promotility drugs. There also may be a role for anti-depressant drugs and dietary changes.
- Future advances in the treatment of dyspepsia depend on a clearer understanding of its cause(s).
