There are many different causes of colic, but in the eastern part of North Carolina there is a special concern of sand colic due to the common soil types of the area. This type of colic is caused by the accumulation of sand and small pieces of gravel in the large colon. Horses fed on the ground, in overgrazed pastures, and in feed lots are at a much higher risk. The signs of sand colic will mimic other types of colic but can also show signs such as diarrhea. You should also look for sand in the feces, because this is another good sign that sand could be settling into the large colon.
