Dear, thank you for asking you noticed that you had a gastric bypass years ago.It s very important for you to remenber that you should be very careful with your post-op nutrition. Things to note: 1. eat frequently, beverages in small sips 2.limit sugar-high foods such as cakes , sodas, jams, jellies. Drink water, herbal tea ,soups, light sugar free fresh fruits and vegetables juices , but be careful do not drink liquids with meals. 3. Please avoid Gatorade drinks expecially in large amounts, because they contains a lot of sugar and can cause other complications. They are not neccesary if you take a healthy diet. Limits other high sugar foods too. 4.Choose high fiber foods such as :whole wheat pasta,cereals, bread ; and foods with proteins such as meat, fish , eggs, milk cheese , yogurt. The most important thing: Please consult a gastroenterology physician, because I suspect for a possible Dumping Syndrome. Hope this was helpfull to you! Best regards, Dr. Ermira Biu
