Equine proximal enteritis the intestinal lumen. Inflammation of the intestine leads to the secretion of a large amounts of electrolytes, primarily sodium and chloride, into its lumen, resulting in the osmotic movement of water. The production of fluid is thought to be due to active hypersecretion, passive secretion of proteins secondary to damage to epithelium of the mucosa and capillaries, and a functional ileus which prevents removal of this fluid. Massive fluid production results in extensive reflux, usually produced at a rate of 50–100 mL/min, in addition to distention of the proximal small intestine, dehydration, and possible shock secondary to hypovolemia.
