Although the vast majority of colic cases are mild, colic is the number one killer of horses. There are a number of causes of colic, which simply refers to abdominal pain in horses. While colic can range in severity from mild to life-threatening, pain relief is almost always necessary. In mild cases, which are often presumed to be the result of an intestinal spasm or excessive gas in the gastrointestinal tract, analgesia is often the only treatment needed. In cases involving an intestinal twist or displacement, surgery is likely necessary. Veterinarians and horse owners must take all cases of colic or suspected colic seriously, because it can be difficult to tell mild cases from those requiring serious intervention such as surgery in early stages.
