Horse Colic: Emergency Recognition and Welfare

Colic is the most common veterinary emergency in horses and a leading cause of death, causing severe abdominal pain that demands rapid recognition and response to minimise suffering and improve survival outcomes.

Key Facts

Colic describes abdominal pain in horses — it is a symptom with over 70 distinct causes ranging from mild gas to life-threatening intestinal torsion
Approximately 10% of horses experience colic each year, and surgical colic cases have a mortality rate of 10-40% even with treatment
Early signs include pawing, looking at the flank, lying down and getting up repeatedly, refusing food, and elevated heart rate
Simple gas colic often resolves with walking and basic analgesia, while displacement and torsion require immediate surgical intervention
The window for successful surgical intervention in severe cases is narrow — delays of even a few hours dramatically reduce survival
Pain assessment tools including heart rate, gut sounds, mucous membrane colour, and capillary refill time guide management decisions
Diet and management factors including pasture access, water intake, feeding consistency, and exercise affect colic risk significantly
Horses recovering from colic surgery require weeks of carefully managed refeeding and exercise restriction
Preventing repeat colic episodes often requires identifying and modifying the contributing management factors
Horse owners who can accurately assess colic severity are better equipped to make timely decisions about veterinary intervention

Welfare Considerations

Colic is one of the most acutely painful experiences a horse can have. Severe abdominal pain causes profound distress — horses in pain from intestinal torsion may throw themselves to the ground repeatedly, roll violently, and show extreme agitation. Delaying veterinary attention in severe cases not only reduces survival odds but prolongs suffering unnecessarily. Owner education about recognising colic severity and knowing when to call the vet immediately rather than adopting a wait-and-see approach is a direct welfare intervention.

What You Can Do

Learn to assess colic severity in horses — take resting heart rate, listen for gut sounds, and assess mucous membrane colour
Call a vet immediately for signs of severe colic — violent rolling, extreme pain, elevated heart rate, or deteriorating condition
Ensure horses always have access to fresh water — dehydration significantly increases impaction colic risk
Feed consistently and introduce dietary changes gradually to minimise digestive disruption
Maintain a regular deworming programme and dental care to reduce colic risk factors
Keep your vet's emergency contact number readily accessible and brief all horse carers on basic colic recognition
