Colic in horses is a very common disorder of their digestive system. The term colic, the basic definition means “abdominal pain”, but in horses is used to define severe abdominal discomfort characterized with rolling, pawing, and seldom the inability to defecate.

What is Colic in Horses?
Colic is the term used to describe a condition that affects mostly ruminants, but can also affect horses. The condition arises when digestive matter moves in an abnormal fashion through the gastrointestinal tract.
Signs of Colic in Horses
Colic is a digestive disease that drastically affects the horse’s well-being and can even be fatal. The colic may affect the intestines, stomach, or both at the same time. Colic signs are divided into four groups to facilitate their identification:
- Abdominal pain
- Abnormal gait
- Severe colicking phenomena
Causes of Equine Colic
The causes of colic are manifold but can be classified into two main categories:
This comes from an obstruction in the intestine that prevents food to pass through it smoothly. This obstruction is usually caused by a solid object, but can also be due to swelling of intestinal contents because of gas entrapment (“the bloated”), or intussusception when one part of the intestine slips inside an adjacent part of the intestine.
Gastrointestinal colic is the result of incoordination between all the organs involved in chewing and digesting food, which causes a spasmodic contraction of the muscles meant to push the food forward from one organ to another until it reaches the stomach. The abdomen fills with gas each time this coordination breaks down. This can be due to colic-causing factors such as:
- Infection (bacteria, virus)
- Toxins (plants or poisonous bites that damage intestinal cells)
- Internal abscesses (identification of which is extremely important for colics that come from bacterial)
- Metabolic colic (hypocalcemia, colitis)
- Sanitary colic is colics caused by external factors such as:
-Digestive disorders (acute intestinal pain)
-Excessive ingestion of food or water
-Getting into problems while being carried in a trailer during transportation
External colic sources are the most common ones since many times they are impossible to avoid or detect until it’s too late. To avoiding colic cases, horses must be fed carefully and regularly, kept in stabling at night, have their teeth checked on a regular basis, and maintain an adequate level of hydration.
Moreover, equine veterinary care should not be postponed when the horse shows colic signs.
The Different Types of Equine Colic
Colic is categorized into four types, colic mild-to-moderate, colic severe-to-acute, colic with distention, colic with impactions, or mechanical obstruction. Treatment varies depending on the type of colic your horse exhibits.
This article will outline treatment for colics in general and will go over each category individually at a later date.
Symptoms of Colic in Horses
Symptoms of colic include kicking at their belly or sides because it hurts, not wanting to eat or drink, becoming quiet after having been very vocal before, and general lethargy.
Treating Equine Colic
The general colic treatment for horses is a combination of medications, supportive care, and some manipulation to clear the intestinal blockage. Surgical colics require additional treatments including surgery itself, antibiotics, and intravenous fluids.
