Which condition can lead to a horse displaying signs of abdominal pain?

Colic is a term used to describe a variety of abdominal pain in horses, often resulting from issues within the gastrointestinal tract. This condition can manifest in several ways, such as distention of the intestines, gas buildup, or blockage, ultimately leading to significant discomfort and pain for the horse. Symptoms of colic can include restlessness, pawing at the ground, rolling, and a lack of appetite.

While choke, laminitis, and sinusitis can cause discomfort and other clinical signs, they do not primarily originate from abdominal issues. Choke is related to obstructions in the esophagus, laminitis involves the hooves and supportive structures of the feet, and sinusitis affects the nasal passages and sinuses. Therefore, colic stands out as the specific condition that directly correlates with abdominal pain in horses.
