When a patient who has undergone a gastric bypass patient eats a sugary food, the sugar passes rapidly into the bowel, where it gives rise to a physiological reaction called dumping syndrome. The symptoms may include rapid heart rate; perfuse sweating, nausea, dizziness and diarrhea. Dumping syndrome is a side-effect of the operation and is best avoided. Dumping syndrome is not meant to be a means to help you lose weight. The best strategy is to avoid the high-calorie sugary foods that cause dumping syndrome which is why it is explained to you both before and after surgery. During the assessment the dietitian explains the importance of modifying your diet and adapting good eating habits before and after the surgery. If you have tried a food with high sugar content suggest that you have already deviated from the dietary guidelines. While having an off day sometimes occurs, do not use the fact that dumping did not occur as an excuse to continue with unhealthy food choices. It is important to take a step back and think about why you would want to continue with this eating pattern. Overindulgence of foods with high sugar content will inhibit weight loss and contribute to weight gain. Now that you have had the surgery you have a second chance to be in control of your intake and to reach your weight loss goals. Print Q&A Send Q&A
