Colic in competing endurance horses presenting to referral centres: 36 cases.

Summary

# Editorial Summary: Colic in Competing Endurance Horses Colic represents a significant threat to endurance horse athletes, commonly forcing competition withdrawal and emerging as the primary cause of death in this population, yet the specific aetiologies and prognostic factors remain poorly characterised. Fielding and Dechant examined 36 endurance horses presenting to referral centres with colic to elucidate underlying causes and clinical outcomes, distinguishing between pathology directly attributable to gastrointestinal disease and metabolic complications arising from the extreme demands of endurance exercise itself. Severe hydration and electrolyte abnormalities were prevalent in affected horses, though these derangements reflected the physiological stress of endurance competition rather than serving as primary drivers of colic development. Understanding the distinction between exercise-induced electrolyte imbalance and true colic pathology is crucial for practitioners managing these cases, as treatment protocols must address both the immediate gastrointestinal crisis and the underlying metabolic disturbances that frequently accompany it. For equine professionals involved in endurance sport—particularly veterinarians making treatment decisions at competitions and between competitions—this work provides essential context for risk stratification and appropriate clinical intervention in what remains a high-stakes scenario.

Key Findings

• •Colic is a common reason for elimination from endurance competitions in horses
• •Colic has been identified as the leading cause of mortality in endurance horses
• •Hydration and electrolyte derangements in colic cases are often severe but likely related to endurance exercise rather than the colic episode itself
