“Colic” generally references pain in the abdomen. Gas colic—sometimes referred to as “spasmodic colic”—is mild to moderate abdominal pain in horses that can resolve on its own or with a single treatment, as opposed to being a symptom of a more serious ailment. Gas buildup within a horse’s digestive tract is thought to be one of the most common causes of colic.1 

Colic can occur at any time of year, frequently arises in the spring, when a horse ingests forage that is high in sugar, such as spring grass. This can lead to excessive fermentation occurring in the gut, with a resulting buildup of gas. Since horses can’t burp, they typically expel gas in the other direction.1 Given the length of the equine intestinal tract however, some gas pockets are not able to escape, resulting in painful distension of the intestinal wall, and colic.2 Although the underlying reason for most gas colic is often never isolated, risk factors for colic include changes in diet and feeding, stabling and activity and health and wellness care.

Symptoms of gas colic may include:

• Pawing

• Kicking or nipping at its flanks

• Stretching out

• Lying down

• Rolling

• Not eating or drinking

• Not passing manure

• Sweating

• Lethargy

• Elevated heart and respiratory rates2

While gas colic is common in horses, a veterinarian should be consulted right away if a horse shows any of these signs, as complications from gas distention can arise if the bowel becomes displaced or twists upon itself.1
