procedure. Other complications may include band migration or slippage,
access port leakage or kinking, esophageal spasm, gastroesophageal reflux
(GERD), and nausea & vomiting.

Dumping Syndrome

Dumping syndrome, also known as rapid gastric emptying, can be an unpleasant result of gastric bypass surgery. It is the body´s response to what it perceives as inappropriate eating, when foods that are high in sugar or fat bypass the stomach too rapidly and dump into the small intestine poorly digested. Symptoms can range from cold sweat and a pounding pulse to severe abdominal cramps, sweating, faintness, nausea and diarrhea lasting up to an hour and prompted immediately following a meal when associated with "early" dumping. "Late" dumping can occur up to three hours following a meal.
