To manage the symptoms of dumping syndrome, regulating dietary habits is of critical importance. High-sugar foods and beverages such as simple sugars, syrupy products, carbonated drinks, fruit juices, and processed foods should be avoided. As lactose in dairy products can worsen symptoms in some individuals, their consumption should be carefully evaluated, or lactose-free options should be preferred. Incorporating high-fiber foods (e.g., whole grains, vegetables, legumes) into the diet can alleviate symptoms by slowing gastric emptying and delaying carbohydrate absorption in the small intestine. Finally, alcohol and tobacco consumption must be strictly avoided.
