Horse colic is one of the most common and potentially serious conditions equine owners and veterinarians encounter. Because it can range from mild and short-lived to a life-threatening emergency, understanding the signs early can make all the difference.
Colic is a broad term used to describe abdominal pain in horses. It is a clinical symptom rather than a single diagnosis, meaning colic can result from a range of gastrointestinal conditions affecting the stomach, intestines or other abdominal organs.
The pain associated with colic often stems from the digestive system’s inability to process food properly, whether due to distention, inflammation or displacement of the intestines. Mild cases may resolve with basic care, while severe cases can become life-threatening if left untreated. According to Merck Veterinary Manual, colic is the leading cause of premature death in domestic horses, which is why early recognition matters.
Several factors can contribute to colic in horses, ranging from diet and environment to underlying health conditions. Common causes include:
Horses with a history of dental problems, high stress levels or frequent NSAID use are also considered higher risk. Age plays a role too — foals, yearlings and horses over 10 years old may be more susceptible to certain GI conditions.
Most horse colic symptoms are behavioral. Changes in how a horse acts are often the first signal that something is wrong. Common signs include:
In more severe cases, you may also notice an elevated heart rate, sweating, rapid or labored breathing and pale or tacky gums. Because horses vary in how they express pain, knowing your horse’s normal behavior is essential to spotting a change early.
If you notice any signs of colic, especially those suggesting a severe episode, contact a veterinarian as soon as possible. A thorough evaluation helps identify the cause and guides the treatment plan.
Diagnostic approaches your veterinarian may use include:
Once your veterinarian identifies the cause and severity of the colic, they will develop a treatment plan tailored to your horse’s specific needs. Treatment options vary depending on the type of colic involved.
Flunixin meglumine (commonly known as Banamine) is an NSAID that veterinarians may prescribe for pain and inflammation associated with colic. It should always be administered under veterinary guidance and does not address the underlying cause of the colic.
For cases involving a blockage, displacement, twisted intestine or tumor that do not respond to medical management, surgery may be necessary. Early surgical intervention improves the prognosis and reduces the risk of further complications. A veterinarian will assess whether surgery is appropriate and may prescribe additional medications before, during or after the procedure.

In addition to veterinarian-directed treatment, owners can take supportive steps to help their horse through a colic episode.
Colic is a general term for abdominal pain in horses. It is a clinical symptom rather than a single disease, meaning it can stem from many different GI conditions, ranging from mild gas buildup to serious intestinal displacement or twisting. Because colic can worsen quickly, any suspected episode should be evaluated by a veterinarian promptly.
The most common signs include pawing at the ground, lying down or rolling, kicking or biting at the flank, poor appetite, lethargy and reduced bowel movements. More severe cases may also involve an elevated heart rate, sweating and pale or dry gums. Any combination of these signs warrants a call to your veterinarian.
Colic can develop from a range of causes including sudden diet changes, dehydration, intestinal blockages, parasites, poor-quality feed, bacterial infections and stress. Horses with dental issues or a history of frequent NSAID use may also face higher risk.
The most common types are gas colic (caused by gas buildup in the large intestine or cecum), impaction colic (caused by a blockage of digested material) and spasmodic colic (caused by irregular intestinal contractions). Displacement and strangulation colic are more serious types that may require surgical intervention to resolve.
Contact a veterinarian as soon as you notice signs of colic. Even mild symptoms can escalate quickly. Signs like an elevated heart rate, continuous rolling, visible distress or changes in gum color indicate a potentially serious episode that requires urgent attention.
Treatment depends on the type and severity of the colic. Veterinarians may prescribe pain management medications, administer fluids via nasogastric tube or recommend surgery for severe cases involving blockages, displacement or intestinal twisting.
While not all colic is preventable, several management practices lower the risk. These include maintaining a consistent forage-based diet, ensuring constant access to fresh water, following a regular deworming schedule, scheduling routine dental care and allowing regular pasture turnout to reduce stress and support healthy digestion.
