Health problems can sometimes occur following Gastric Bypass surgery. One of the most common problems is Dumping Syndrome. Dumping Gastric Bypass occurs when the patient's stomach empties too quickly and food enters the small intestine undigested. Symptoms of early dumping after Gastric Bypass include nausea, vomiting, stomach cramps, diarrhea, dizziness, bloating and fatigue. While symptoms of late dumping include weakness, dizziness and sweating. In order to prevent Dumping Syndrome, Gastric Bypass patients should eat small meals that are low in carbohydrates and high in fiber. Medications can also be given to slow the digestive process, if necessary.
