*'''Primary causes:''' [[Gastric Impaction - Horse|gastric impaction]], food engorgement, excessive water intake after exercise, aerophagia and parasitism(141,146). Excessive consumption of fermentable feeds (grains, lush grass, and beet pulp) causes a large increase in the production of volatile fatty acids which is thought to delay gastric emptying.(Merck)

*'''Secondary causes:''' primary intestinal ileus or small or large intestinal obstruction. Dilation resulting from small intestinal obstruction is the most common cause. Fluid from the obstructed small intestine accumulates in the stomach, causing [[Colic Diagnosis - Naso-gastric Intubation|naso-gastric reflux]]. Gastric dilation may also occur with certain colonic displacements, especially '''right dorsal displacement of the colon''' around the caecum. It is hypothesised that the displaced colon obstructs duodenal outflow. Gastric fluid accumulation is also characteristic of '''proximal enteritis-jejunitis'''.(Merck)
