===Description===  

Impaction of the large colon is seen in horses with limited access to drinking water or those grazing bare pastures. Horses fed on a low-roughage diet are more prone to developing the condition. The ingested sand accumulates and forms a sediment within the right dorsal colon, pelvic flexure and transverse colon. This type of colic is particularly common in dry sandy regions of the world and is far less common in the UK and rest of Europe.  

Impaction of the large colon is seen in horses with limited access to drinking water or those grazing bare pastures. Horses fed on a low-roughage diet are more prone to developing the condition. The ingested sand may act as an inflammatory stimulus, causing a foreign body enteritis. Alternatively it may accumulate and form a sediment within the right dorsal colon, pelvic flexure and transverse colon, leading to an impaction.
