What is Colic in Horses?
Colic is a common medical issue among horses.
While most cases can be managed medically, some may require emergency surgery.
Horses displaying signs of colic should be examined by their veterinarian promptly.
Early diagnosis and treatment will improve the horse’s chances for recovery.
Colic is a common issue among horses, and it’s essential to identify its causes. There could be many potential causes for colic, and if not diagnosed and addressed promptly, colic could prove fatal for your horse.
Colic in horses often indicates an underlying disease or injury to their intestines. If left untreated, colic could become a serious issue requiring surgical intervention.
Horses may experience several types of colic, including gas colic, obstructive lesions, and functional obstructions.

Colic in Horses
Colic in horses is a term used to describe a range of gastrointestinal disorders that cause abdominal pain.
It is one of the most common and serious health issues in horses, requiring prompt attention and, in some cases, emergency medical intervention.
Understanding colic’s signs, causes, and treatments can help horse owners manage this potentially life-threatening condition effectively.
Understanding Colic
- Definition:
- Colic refers to any condition causing abdominal pain in horses. It is not a single disease but a symptom of various underlying issues affecting the gastrointestinal tract.
- Severity:
- Colic can range from mild to severe. Mild cases may resolve on their own or with minimal treatment, while severe cases can be life-threatening and may require surgical intervention.
- Types of Colic:
- Gas Colic: Caused by excessive gas buildup in the intestines or stomach, leading to distension and pain.
- Spasmodic Colic: Results from intestinal spasms or cramps, often due to changes in diet or environment.
- Impaction Colic: Occurs when feed, sand, or other material obstructs the intestines.
- Displacement/Torsion: The twisting or displacement of the intestines can cut off blood supply and cause severe pain.
- Enteritis/Colitis: Inflammation or infection of the intestines, leading to discomfort and pain.
- Sand Colic: Caused by the accumulation of sand in the intestines, common in horses grazing on sandy soils.
Signs and Symptoms of Colic
Recognizing the signs of colic early can significantly affect the outcome. Common symptoms include:
- Behavioral Signs:
- Restlessness and frequent lying down and getting up.
- Pawing at the ground or looking at the flanks.
- Rolling or thrashing on the ground.
- Stretching as if to urinate frequently.
- Physical Signs:
- Lack of appetite and decreased interest in food and water.
- Reduced or absent gut sounds (intestinal noises).
- Sweating, often in patches.
- Rapid or irregular heartbeat and breathing.
- Distended abdomen and visible discomfort.
- Other Indicators:
- Changes in manure consistency or frequency.
- Depression or lethargy.
- Grinding of teeth or other signs of pain.
Causes of Colic
Several factors can contribute to the development of colic in horses:
- Dietary Issues:
- Sudden changes in diet, such as switching feed types or introducing rich pasture.
- Poor-quality feed or hay.
- Inadequate water intake leads to dehydration and impaction.
- Management Practices:
- Lack of regular exercise or sudden changes in activity level.
- Stress from changes in environment, routine, or herd dynamics.
- Inadequate dental care leads to improper chewing and digestion.
- Environmental Factors:
- Grazing on sandy soils can lead to sand colic.
- Exposure to toxic plants or substances.
- Health Conditions:
- Parasite infestations can cause intestinal damage and blockages.
- Pre-existing gastrointestinal disorders or anatomical abnormalities.

Treatment of Colic in Horses
The treatment of colic depends on its severity and underlying cause. Immediate veterinary attention is essential for proper diagnosis and treatment. Common treatment approaches include:
- Initial Assessment:
- A veterinarian will perform a physical examination, including checking vital signs (heart rate, respiratory rate, temperature) and listening for gut sounds.
- Nasogastric intubation may be performed to check for gastric reflux and relieve gas or fluid buildup.
- Medical Treatment:
- Pain Relief: Administering analgesics or anti-inflammatory medications to alleviate pain.
- Fluids: Providing intravenous or oral fluids to rehydrate and help resolve impactions.
- Laxatives: Using laxatives or mineral oil to lubricate the intestines and facilitate the passage of impactions.
- Anti-spasmodics: Administering medications to reduce intestinal spasms.
- Surgical Intervention:
- Severe cases of colic, such as those involving intestinal torsion or displacement, may require surgery to correct the problem and remove any blockages.
- Post-Treatment Care:
- Monitoring the horse closely for signs of recurrence or complications.
- Adjusting diet and management practices to prevent future episodes.
Prevention of Colic
While not all cases of colic can be prevented, following good management practices can reduce the risk:
- Diet and Nutrition:
- Provide a consistent, high-quality diet with gradual changes to feed and forage.
- Ensure access to clean, fresh water at all times.
- Avoid feeding large amounts of grain or rich feed in one sitting; provide smaller, more frequent meals instead.
- Exercise and Management:
- Ensure regular exercise and turnout to promote gut motility.
- Maintain a consistent routine to minimize stress.
- Implement good parasite control measures, including regular deworming and fecal egg count monitoring.
- Dental Care:
- Schedule regular dental check-ups to ensure proper chewing and digestion.
- Environmental Management:
- Avoid grazing on sandy soils or use feeding mats to minimize sand ingestion.
- Ensure pastures are free from toxic plants and other hazards.
Colic in Horses – Diagnosis
Colic can be a frightening experience for horse owners, but the diagnosis is usually straightforward.
Most horses that present with colic have some digestive issue – this could be caused by an enlarged bowel or something more serious like a tumor, abscess, or infection.
When your horse exhibits signs of colic, you must contact your veterinarian immediately. Colic can become a medical emergency and lead to death if left untreated.
Your vet will examine your horse carefully, looking for any signs that indicate an intestinal problem.
He or she will examine its feces, pulse, and respiration; if there has been no food or drink recently, they will also inspect its skin and feces for indications of previous colic episodes.
If the veterinarian detects your horse exhibiting these symptoms, they will begin treatment.
Medication will be given to control pain and help the animal relax. In some cases, medications like Banamine (flunixin meglumine) may be prescribed to keep your horse from clicking.
If your horse has colic, a veterinarian can physically examine the abdomen.
They may also perform a rectal exam and insert a nasogastric tube into the stomach to check for excess fluid buildup.
A vet may also be able to detect other potential issues by performing an abdomen ultrasound. An ultrasound can reveal whether a tumor or small intestinal lesion is causing colic symptoms.
Sometimes, the issue is more serious and requires surgery to resolve.
Surgeons may need to remove the affected portion of the intestine or anus to correct the situation and prevent your horse from experiencing colic again.
Another condition that may cause colic is meconium impaction.
This occurs when the intestines cannot pass a certain amount of food and begin to swell. It usually results in symptoms within 12-24 hours.
Colic in Horses – Conclusion
Colic is a serious condition that requires prompt attention and proper management.
Understanding the signs, causes, and treatments of colic can help horse owners respond effectively and reduce the risk of severe outcomes.
By implementing good dietary, management, and healthcare practices, you can minimize the likelihood of colic and ensure the well-being of your horse.
Regular veterinary check-ups and being vigilant about changes in your horse’s behavior and health are essential for early detection and treatment of colic.
