What condition is characterized by severe abdominal pain in a horse?

Colic is the condition characterized by severe abdominal pain in horses. It can arise from various underlying issues, including digestive blockages, twisted intestines, or excessive gas production. The symptoms of colic often include signs of distress, such as looking at their belly, pawing at the ground, pacing, and rolling. Prompt recognition and treatment of colic are crucial because it can lead to serious complications, including intestinal rupture if not addressed in a timely manner.

The other conditions listed do not primarily cause severe abdominal pain. Thrush, for example, is a hoof condition that affects the frog and sole, causing pain in the foot rather than the abdomen. An abscess, while painful, typically pertains to localized infections or pockets of pus in a specific area (such as the hoof) and does not generally present with abdominal pain. Mud fever, which is a skin infection often related to wet conditions, affects the legs and skin, causing discomfort in these areas without causing the abdominal distress seen in colic.
