Introduction:
Most patients with uninvestigated dyspepsia are diagnosed with functional dyspepsia. Various types of Helicobacter pylori gastritis have been described, each of which is associated with a distinct natural history of the infection (i.e. a different risk of ulcer or gastric cancer).
Objective:
To determine the clinical and pathological characteristics of patients with uninvestigated dyspepsia in our area and the prevalence of the distinct types of H. pylori gastritis among patients with functional dyspepsia.
Material And Methods:
Ninety-eight patients (47 men and 51 women, mean age 35.8+/-13 years) with uninvestigated dyspepsia were included in this study. All the patients completed the Dyspepsia-Related Health Scale and all patients underwent gastroscopy with biopsy and the C13-urea breath test.
Results:
Fourteen patients had organic causes of dyspepsia and 78 had functional dyspepsia. Fifty-one patients with functional dyspepsia (65%) had H. pylori infection; of these, 27 had pangastritis, 21 had antrum-predominant gastritis, 2 had multifocal atrophic gastritis and 1 had normal gastric mucosa. Among uninfected patients, 2 had multifocal atrophic gastritis.
Conclusions:
The prevalence of functional dyspepsia in this series was 85%. Twenty-seven percent of patients with functional dyspepsia had a combination of H. pylori infection and antrum-predominant gastritis, the type of gastritis predisposing to duodenal ulcer. Only 5% of the patients had multifocal atrophic gastritis, which is associated with a high risk of gastric cancer.

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
