Equine Gastric Ulcer Syndrome (EGUS) is a common cause of mild to moderate colic, and is more prevalent than had been appreciated.  In racehorses, the prevalence is as high as 90%.  In other performance horses, prevalence ranges from 40-60%.  In foals, prevalence is approximately 25%, and probably higher in those being hospitalized for other reasons.<!-- Murray's work would be a good source...don't have it here right now -->

[[Gastric Ulceration - Horse|Equine Gastric Ulcer Syndrome (EGUS)]] is a common cause of mild to moderate colic.

 

In adult horses, ulceration commonly occurs in the non-glandular portion of the stomach, unlike in humans, where [[peptic ulcers]] are far more common.  While the bacterium ''Helicobacter pylori'' is a common cause of ulcers in humans, equine gastric ulcers are not typically infectious in origin.  It is thought that EGUS is often stress-related, such as after travelling or confinement, and gastric ulceration is a known potential side-effect of treatment with [[non-steroidal anti-inflammatory drugs|non-steroidal anti-inflammatory drugs]].  A diet consisting of a high proportion of concentrates is also considered a risk factor.  In affected horses, pain is often associated with eating, and the horse typically takes one or two bites of food, then no more.  A definitive diagnosis requires [[endoscopy]].  Treatment is usually effected using [[H2 antagonist|H₂ receptor antagonists]], such as [[Cimetidine]], or [[proton pump inhibitors]], such as [[Omeprazole]].
