Colic, Undiagnosed Conditions Causing

There are literally hundreds of conditions of the intestine that can cause colic (abdominal pain).

Many simple cases of abdominal pain (colic) are not definitively diagnosed but respond to simple treatment. By default, vets often call these “spasmodic” or “gas-type” colic episodes. In many cases, the causes of colic episodes are not diagnosed. In other cases, even with diagnostics, the condition causing colic is not known until and unless exploratory colic surgery is performed.

If these episodes persist or worsen, you should consider investing in additional diagnostics to help narrow the problem and reach a diagnosis.

Do your best to help your vet by providing as much information about your horse’s history and management as possible.
