Which illness is characterized by abdominal pain due to a displaced or twisted gut?

Colic is indeed characterized by abdominal pain that can arise from various causes, including conditions like a displaced or twisted gut, also known as volvulus or torsion. In horses and other animals, colic can manifest through signs of severe discomfort, such as rolling, sweating, and pawing at the ground, indicating distress caused by gastrointestinal issues. The twisting or displacement of the intestines can lead to compromised blood flow and severe pain, which makes it crucial for understanding the nature of colic, as it requires prompt veterinary intervention to relieve the pain and address the underlying issue.

Other conditions listed, like lameness, thrush, and kissing spine, are related to musculoskeletal and dermatological issues, typically affecting mobility or the health of the hoof, but do not involve the gut or the hallmark symptom of abdominal pain associated with digestive disturbances. Therefore, colic stands out as the correct answer for this question regarding abdominal pain linked to gastrointestinal displacement or twisting.
