Colic is actually not one condition; it is a catchall name for several different serious digestive problems that commonly afflict horses. Make no mistake: You must deal with suspected colic immediately, as all forms can be fatal. The condition can be caused by a blockage of the intestines (caused by improper food, foreign objects, or other factors), excessive gas in the intestines (usually caused by a rapid change in diet), or the intestines becoming twisted (causes not well understood). Colic can also be caused by some gastrointestinal parasites.
