Prevalence of Gastritis among Morbidly Obese Patients Subjected to Laparoscopic Sleeve Gastrectomy at a Tertiary Hospital, Makkah, Saudi Arabia.

ABSTRACT: Background and Objective: Morbidly obese persons often get gastritis after laparoscopic sleeve gastrectomy (LSG). The study examined the prevalence of gastritis and associated risk factors after LSG at a tertiary hospital in Saudi Arabia. Materials and Methods: The present retrospective cross-sectional study comprised patients with obesity aged 18 and older who received LSG between 2019 and 2023. Pre- and post-operative gastritis symptoms, results, and risk factors were examined. Results: The study involved 343 patients. Gastritis was common after LSG, affecting 70.3% of patients. Gastritis was approximately twice as likely in women as in men. Hypothyroidism and cesarean section history increased gastritis risk by five-fold and three-fold, respectively. H. pylori infection increased the risk of gastritis seventeen-fold after surgery. Conclusion: Significant risk variables were female gender, hypothyroidism, cesarean section history, and H. pylori infection. [ABSTRACT FROM AUTHOR]
