A new computational model coupling gastric fluid flow, acid transport, and pathogen kinetics finds that reduced motility allows nearly 50% pathogen survival at 6 minutes versus under 30% in healthy cases, showing motility dominates gastric sterilization.
Simulations in a human stomach model quantify how reduced peristaltic amplitudes affect protein hydrolysis rates, emptying rates, and mixing induced by antral waves.
