Diagnosis can be made on [[Rectal examination of the Horse|rectal examintion]], the caecum is firmer and filled with ingesta and can be indented digitally. The caecal mass will be palpated in the right paralumbar area, identified by the taut ventral caecal band and the fat and blood vessels overlying the medial caecal band.

[[Dehydration - Pathology|Dehydration]] develops as the impaction becomes estabilised; in most cases the impaction is not sufficiently severe or prolonged to cause cardiovascular compromise or changes in peritoneal fluid, but if the case is chronic or progresses to rupture then the condition is serious and the horse should be closely monitored for worsening clinical signs. There will be an increase in the protein content of peritoneal fluid as well as cardiovascular signs of shock as the caecum becomes grossly distended, ischaemia of the visera occurs and toxaemia develops as the caecum eventually ruptures.
