In brief: Blocked pipes
The stomach and small bowel secrete gallons of fluid every day that is reabsorbed, aiding nutrient absorption.
If the small intestine is obstructed, this fluid upstream from the blockage accumulates and, left with no place to go, backs up into the stomach.. Also, we all swallow air--this furthers the upstream distention. A key sign of successful resolution is gas +/- stool out the bottom.
