What causes thickening of small intestine in horses?

Proliferative enteropathy in juvenile horses caused by Lawsonia intracellularis is considered by some authors to be an equine inflammatory bowel disease, but thickened intestine in affected horses is caused by hyperplasia of enterocytes in the intestinal mucosa rather than by infiltration of inflammatory cells.

Are older horses more prone to colic?

Colic risk does increase in senior horses. Gut motility issues are more common in older horses, which can lead to an increased risk of impaction colic. Other issues in the senior gastro-intestinal tract which elevate the risk of colic can include tumors or increased parasite load.

How serious is a twisted small intestine?

Untreated, intestinal obstruction can cause serious, life-threatening complications, including: Tissue death. Intestinal obstruction can cut off the blood supply to part of your intestine. Lack of blood causes the intestinal wall to die.
