Colic in Horses: Understanding the Causes, Symptoms, and Preventative Measures

Horse colic is one of the most common and potentially life-threatening conditions affecting horses. While the term "colic" is frequently used, it actually refers to any type of abdominal pain rather than a single disease.

Understanding the causes, symptoms, prevention, and treatment of colic is essential for horse owners to provide the best possible care for their horses.

What is Colic?

Colic refers to discomfort in the abdomen, which can range from mild digestive upset to severe pain caused by intestinal blockages or twists.

Horses have a unique digestive system that makes them especially vulnerable to colic. Their stomachs are relatively small compared to their body size, and they require constant small amounts of food throughout the day for proper digestion.

Causes of Horse Colic

Colic can be triggered by a range of factors, including:

✅ Dietary Issues

• Sudden changes in diet can disrupt gut bacteria.
• Poor-quality or mouldy hay can cause irritation.
• Overeating can lead to stomach overload.

✅ Lack of Water Intake

• Dehydration slows digestion, increasing the risk of colic.

✅ Inadequate Exercise

• Lack of movement can lead to digestive slowdowns.

✅ Parasites

• High parasite loads can irritate the digestive system.

✅ Stress

• Travel, environmental changes, or competition stress can increase colic risk.

✅ Intestinal Obstructions & Twists

• Severe cases occur when the intestines become blocked or twisted, cutting off blood flow.

✅ Gas Colic

• Caused by gas buildup from fermentation in the intestines.

Symptoms of Colic in Horses

Recognizing early signs of colic is critical for effective treatment. Watch for:

🔴 Pawing at the ground or kicking at the abdomen.
🔴 Looking at the flank or biting at the belly.
🔴 Rolling excessively or attempting to lie down.
🔴 Sweating and increased heart rate.
🔴 Loss of appetite or refusal to eat/drink.
🔴 Restlessness or unusual behaviour.
🔴 Decreased manure production or gut sounds.

Types of Colic

Colic is classified based on its cause and severity:

1️⃣ Spasmodic Colic – Caused by intestinal cramps and spasms, often mild.
2️⃣ Impaction Colic – A blockage caused by dry feed or poor-quality hay.
3️⃣ Gas Colic – Gas buildup in the intestines, leading to bloating.
4️⃣ Torsion or Twisted Gut – A severe and life-threatening form of colic where the intestine twists on itself, requiring emergency surgery.

Treatment for Colic

The treatment for colic depends on its severity.

1️⃣ Mild Cases

• Pain relief medication (NSAIDs).
• Oral or IV fluids to promote digestion.

2️⃣ Severe Cases

• Surgery may be required for twisted intestines or severe obstructions.
• Hospitalisation for pain management and monitoring.

3️⃣ Emergency Veterinary Care

• If symptoms worsen or persist, a vet must be called immediately.

Preventing Colic in Horses

While colic cannot always be prevented, following these best practices reduces the risk:

✅ Proper Feed Management

• Make gradual changes to your horse’s diet.
• Ensure access to fresh, high-quality hay and water.

✅ Regular Exercise

• Daily movement promotes gut motility.

✅ Parasite Control

• Regular deworming prevents digestive damage.

✅ Minimise Stress

• Maintain a calm, consistent environment.

✅ Monitor Water Intake

• Ensure proper hydration, especially in hot or cold weather.
