Background:
Previous studies have identified a potential association between anxiety and gastritis, attracting widespread interest in recent years. However, empirical research examining the bidirectional relationship between anxiety and gastritis using a large-scale, real-world population is limited.
Methods:
Using a bidirectional cohort design with 502,357 UK Biobank (UKB) participants, multivariable logistic regression was conducted to evaluate the association between anxiety and gastritis. Additionally, Cox proportional hazards models were employed to evaluate temporal risk patterns, while receiver operating characteristic (ROC) curves were plotted to assess predictive performance. Lastly, Kaplan-Meier analysis was performed to evaluate survival differences, adjusting for age, sex, body mass index (BMI), and socioeconomic covariates.
Results:
Anxiety disorders were independently associated with an increased risk of gastritis in both logistic regression (adjusted OR = 1.35, 95 % CI: 1.30-1.39) and Cox models (adjusted HR = 1.51, 95 % CI: 1.46-1.57). Moreover, patients with gastritis exhibited a twofold increased risk of anxiety (adjusted HR = 2.21, 95 % CI: 2.14-2.29), validating a bidirectional causality between anxiety disorders and gastritis.
Conclusion:
This large-scale bidirectional cohort study demonstrated a reciprocal association between anxiety and gastritis. Clinically, integrated psychosomatic care is warranted during the critical post-diagnosis window for both anxiety and gastritis.

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...

Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...
01:28Peptic Ulcer Disease III: Clinical Manifestations and Diagnostic Studies
Few clinical manifestations differentiate gastric ulcers from duodenal ulcers. Distinctions in the location, timing, and pain relief are crucial for healthcare providers in differentiating between gastric and duodenal ulcers during clinical assessments.
01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
