Horse Colic: Recognising and Responding to a Life-Threatening Emergency

Colic is the most common cause of death in horses and a significant welfare emergency. Rapid recognition of signs and immediate veterinary response are critical to minimising suffering and improving outcomes.

Key Facts

Colic refers to abdominal pain in horses and encompasses many different conditions from mild gas to surgical emergencies
Approximately 10% of horses experience at least one colic episode per year
Colic is the leading cause of premature death in horses, responsible for approximately 28% of equine deaths
Signs include pawing, looking at flanks, sweating, rolling, refusing food, and elevated heart rate
Impaction colic — caused by intestinal obstruction from food material — is among the most common forms
Surgical colic (requiring abdominal surgery) carries significant mortality even with optimal care
Prompt veterinary assessment reduces pain duration and improves outcomes across all colic types

Welfare Considerations

Colic causes acute abdominal pain of variable severity — from mild discomfort to excruciating, unrelenting pain in severe surgical cases. Horses in severe colic show extreme distress, rolling violently, sweating, and exhibiting signs of pain that are distressing to witness. The welfare imperative is rapid recognition and immediate veterinary contact. Delay in calling a veterinarian — often driven by owner uncertainty or hope that the episode will resolve — can convert a manageable condition into a life-threatening emergency with prolonged suffering.

What You Can Do

Learn to recognise early colic signs — subtle changes like reduced manure, unusual posture, or flank watching
Call a veterinarian immediately if you suspect colic — do not wait to see if it resolves on its own
Remove access to food while awaiting veterinary assessment but ensure fresh water is available
Walk a mildly colicking horse gently if it is trying to roll — walking can help mild cases and prevent injury from violent rolling
Know your horse's resting heart rate — elevated rate (above 48 bpm) is an important severity indicator
Discuss colic risk management with your veterinarian including diet, water intake, parasite control, and dental care
