NCIt definition : A disorder of the gastrointestinal tract. It is typically caused by the rapid emptying
of undigested food from the stomach to the small intestine following gastroesophageal
surgery but may be seen secondary to diabetes or the use of certain medications. Clinical
signs may be seen 30-60 minutes after eating (early dumping): cramping, nausea, vomiting
and diarrhea or they may be seen 1-3 hours later as a result of hyperinsulinemic hypoglycemia
(late dumping): sweating, dizziness, confusion and heart palpitations. Untreated,
the clinical course progresses to malnutrition and weight loss.;
Alternative definition : NCI-GLOSS: A group of symptoms that occur when food or liquid enters the small intestine
too rapidly. These symptoms include cramps, nausea, diarrhea, and dizziness. Dumping
syndrome sometimes occurs in people who have had a portion of their stomach removed.;
