Summary

This study looks at whether people with a certain stomach lining condition (chronic atrophic gastritis) have different indigestion symptoms than those without it. Researchers will compare symptom patterns in about 315 adults who recently had an endoscopy. The goal is to better understand the link between these conditions and improve how doctors diagnose and manage symptoms.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

Adult patients (aged 18-75 years) with endoscopic findings suggestive of chronic atrophic gastritis within the past 12 months at the Third Affiliated Hospital of Zhejiang Chinese Medical University. Target enrollment: 258-315 patients to ensure at least 80 pathologically confirmed non-CAG cases. Eligible patients undergo endoscopy for dyspeptic symptoms, surveillance, or upper abdominal discomfort. All undergo standardized 5-point gastric biopsy per Updated Sydney System for histopathological classification into CAG or non-CAG groups. Both symptomatic and asymptomatic patients are eligible; no H. pylori status restrictions. Exclusions: organic GI diseases (peptic ulcer, gastric cancer, IBD), autoimmune gastritis, severe systemic diseases, inability to consent. Consecutive recruitment from routine clinical practice ensures representative sampling.
