Colic is the leading cause of horse death and causes significant acute suffering; many types are preventable through good management of diet, water access, and parasite control.
Colic causes acute abdominal pain that can range from mild transient discomfort to life-threatening surgical emergency. The welfare impact of severe colic is profound: horses in pain roll, thrash, and show obvious distress that can last hours before veterinary intervention achieves relief. Many common colic causes are preventable: adequate water access prevents impaction; gradual dietary changes prevent fermentative colic; strategic parasite management prevents parasitic damage. Veterinary attention promptly when colic is suspected prevents deterioration from mild to life-threatening. The welfare burden of colic across the equine population represents significant suffering that good management can substantially reduce.
