Distension of the stomach elicits a reflex increase in peristaltic contractions in the colon; vagal sensory receptors in wall of stomach initiate effect.

increase of muscle movement in the gastrointestinal tract when food enters an empty stomach, which may cause the urge to have a bowel movement right after eating.

Automatic (reflex) wave-like movements of the large intestine (bowel), in response to food entering the stomach and small intestine. This moves material through the bowel.

Activation in the gastrointestinal tract immediately after eating.

The gastrocolic reflex or gastrocolic response is one of a number of physiological reflexes controlling the motility, or peristalsis, of the gastrointestinal tract. It involves an increase in motility of the colon in response to stretch in the stomach and byproducts of digestion in the small intestine. The small intestine also shows a similar motility response.
