The clinical signs associated with gastric ulcers are often very non-sepcific, difficult to document and at times only subjective.(Orsini) In addition, there appears to be a poor correlation between the severity of endoscopic lesions and the clinical presentation.(Murray et al 1989 in Orsini) The significance of gastric ulceration in horses thus remains questionable. However, there have been instances in which ulcer treatment has preceded an improvement in clinical status and/or racing perfomance, suggesting that in some horses, ulcers are a considerable burden.(Orsini) Horses with gastric ulcers are often asymptomatic, but signs that have been attributed to these lesions include:

**In one study, 49% of horses that presented for colic had gastric ulceration and those with duodenitis-proximal jejunitis had a trend towards a higher prevalence of gastric ulceration compared to those with other GI lesions.(Dukti et al. 2006) (Nadeau 2009)
