A mathematical model is considered to study peristaltic transport of chyme in the small intestine during gastroenteritis infection. The Jeffrey model fluid flow is used for the peristaltic flow of chyme in the intestine. The assumptions of peristaltic rush waves and asymmetric channel of the inner part of the small intestine are made. The equations governing the flow are simplified by applied low Reynolds number and long wave approximation. Exact solutions are obtained for velocity and pressure rise. The numerical computations are presented graphically. It is found that the frictional parameter favour the forward movement of chyme through the small intestine during gastroenteritis infection.
