What is Equine proximal enteritis?

Proximal enteritis, also known as anterior enteritis or duodenitis-proximal jejunitis , is inflammation of the duodenum and upper jejunum. It produces a functional stasis of the affected intestine and hypersecretion of fluid into the lumen of that intestine. This leads to large volumes of gastric reflux, dehydration, low blood pressure, and potentially shock. Although the exact cause is not yet definitively known, proximal enteritis requires considerable supportive care.
