The stomach is a muscular sac that is important for absorbing food and preparing food for further digestion.
Dumping syndrome also referred to as gastric dumping syndrome or rapid gastric emptying is characterized by rapid entering of undigested food from the stomach into the small intestine. Due to this the small intestine is expanded too quickly as the hypertonic contents of the stomach causes rapid shift of fluid or water into the lumen of the intestine leading to contraction of plasma volume acute distension of intestine. Symptoms of early dumping begins within 15-30 minutes after eating a meal and include nausea and vomiting, intestinal bloating, diarrhea, intestinal cramping, fatigue and dizziness. Symptoms of late dumping occur 1-3 hours after eating a meal and include sweating, weakness, and dizziness (symptoms of hypovolemia). Dumping syndrome usually occurs in individuals who had a gastric bypass surgery (Roux-en-Y surgery). Dumping syndrome is more likely to occur with ingestion of certain types of foods such as refined sugars, dairy products and certain fried foods.
