Why does enteric nervous system dysfunction often disrupt small intestine nutrient absorption following bariatric surgery?

💡 Explanation

Uncoordinated peristalsis impairs efficient mixing of chyme with digestive enzymes and the intestinal wall for absorption, because proper neuronal signaling controls the muscular contractions. Therefore, nutrient uptake is reduced, rather than a primary enzyme deficiency or bile salt issue, which are less direct enteric effects.
