Correlation Study of Atrophic Gastritis and Dyspepsia Symptoms

Background: Dyspepsia is a common gastrointestinal complaint globally, affecting approximately 21.8% of the population. Among patients presenting with dyspeptic symptoms, over 80% are diagnosed with functional dyspepsia (FD), while approximately 16% are found to have chronic atrophic gastritis (CAG). CAG represents an important precancerous condition in the gastric cancer cascade, yet the relationship between pathologically confirmed CAG and dyspeptic symptoms remains poorly understood. The significant symptom overlap between CAG and FD creates diagnostic challenges in clinical practice. Study Objectives: The primary objective is to determine whether there are significant differences in the prevalence and severity of dyspeptic symptoms (including epigastric pain, burning sensation, early satiety, and postprandial fullness) between patients with pathologically confirmed CAG and those without CAG (non-CAG group) among individuals who present with endoscopic features suggestive of atrophic gastritis. Secondary objectives include: (1) analyzing the independent effects of various covariates (Helicobacter pylori infection, dietary habits, sleep quality, psychological factors) on dyspeptic symptoms; (2) developing a symptom-based predictive model for pathological CAG; and (3) conducting exploratory serum metabolomics analysis to identify potential biomarkers and metabolic pathways associated with FD symptoms. Study Design: This is a single-center, prospective, observational st…
