Gastroenterol Clin North Am. 2023 Jun;52(2):403-415. doi: 10.1016/j.gtc.2023.03.008. Epub 2023 Apr 7.

Abstract

Obesity exerts both direct and indirect effects on gastrointestinal function. From physical effects of central adiposity on intragastric pressure resulting in higher incidence of reflux to dyslipidemia and effects on gallstone disease, the gastrointestinal manifestations of obesity are wide-ranging. Of particular emphasis is the identification and management of non-alcoholic fatty liver disease including non-invasive assessment and lifestyle and pharmacologic interventions for patients with non-alcoholic steatohepatitis. Additional focus is on the impact of obesity and western diet on intestinal disorders and colorectal cancer. Bariatric interventions involving the gastrointestinal tract are also discussed.

Keywords: Barrett’s esophagus; Cholelithiasis; Colorectal cancer; Non-alcoholic fatty liver disease; Nonalcoholic steatohepatitis.
