Dumping syndrome is a condition where ingested foods bypass the stomach too rapidly and enter the small intestine largely undigested. It can begin during or right after a meal. Symptoms include nausea, vomiting, bloating, cramping, diarrhea, dizziness and fatigue. Dumping may also happen one to three hours after eating. Symptoms of this late dumping include weakness, sweating, and dizziness. In addition, people often suffer from low blood sugar, or hypoglycemia, because the rapid dumping of food triggers the pancreas to release excessive amounts of insulin into the bloodstream. Dumping syndrome is associated with difficulty digesting fats and carbohydrates.
