9.1 Gastric Emptying Speed

Gastric Emptying Speed defines the timing by which gastric contents enter the small intestine. It affects fat entry concentration and Gastric Hair Residence Time.

Slower gastric emptying can be physiological under higher-fat structure. Physiological slowing is not the same as pathological gastric motility disorder.

Slower emptying can increase gastric hair residence time and Hair Entanglement Probability. Vomiting, pain, food refusal, and obstruction suspicion enter Clinical Boundary Layer.

Upstream fat and physical form set emptying pacing.

Release timing relative to digestive load.

Hairball vomiting is an output event for backtrace—not proof of motility disease by default.
