Obesity has a pervasive influence on gut health, influencing the structure and function of the gastrointestinal tract. Increased body weight may raise the risk of disorders like gastroesophageal reflux disease (GERD), fatty liver disease, gallstones, and changes in gut microbiota. This session will discuss the mechanisms that connect obesity with gastrointestinal disorders, examine diagnostic strategies, and emphasize nutritional, lifestyle, and medical measures to enhance gut health. Participants will receive pragmatic advice for treating gastrointestinal complications in patients who are obese, enhancing general well-being and life quality.
