The National Institute of Diabetes and Digestive and Kidney Diseases states that excess hormones caused by too fast movement of food through the body and the movement of fluids into the small intestine causes symptoms of rapid emptying syndrome. This excess of hormones can cause the pancreas to produce too much insulin. This insulin overproduction can cause low blood glucose levels 1 to 3 hours after eating, causing symptoms of rapid emptying syndrome hours after eating. In general, you can help prevent rapid emptying syndrome by changing your diet after surgery.
Changes may include eating smaller meals and limiting foods that are high in sugar. In more severe cases of rapid emptying syndrome, you may need medication or surgery.
