Dumping Syndrome

The term dumping syndrome refers to an unpleasant set of vasomotor and GI symptoms that sometimes occur in patients who have had gastric surgery or a form of vagotomy. It may be the mechanical result of surgery in which a small gastric remnant is connected to the jejunum through a large opening. Foods high in carbohydrates and electrolytes must be diluted in the jejunum before absorption can take place, but the passage of food from the stomach remnant into the jejunum is too rapid to allow this to happen. The symptoms that occur are probably a result of rapid distention of the jejunal loop anastomosed to the stomach.

The hypertonic intestinal contents draw extracellular fluid from the circulating blood volume into the jejunum to dilute the high concentration of electrolytes and sugars. The ingestion of fluid at mealtime is another factor that causes the stomach contents to empty rapidly into the jejunum.
