The most common colic symptoms in horses include abdominal pain, restlessness, and increased heart rate. If a horse has colic, it might also show symptoms such as sweating and an elevated temperature.
In most cases of colic, the gas is trapped within the intestines. This causes abdominal distension with pain that sometimes horses are trying to relieve by rolling on their back or kicking. The pain may cause the horse to become restless and even refuse food and water.
Colic can be a life-threatening condition if not treated, therefore it's important to recognize the symptoms as soon as they occur and get veterinary care for your horse right away.
