What You Need to Know About Gastric Ulcers in Horses

Author: The Horse: Your Guide to Equine Health Care May 22, 2026 Duration: 59:45

Gastric ulcers are common in both performance and pleasure horses, but the clinical signs can be easily overlooked. Affected horses might show poor performance, changes in attitude, decreased appetite, or unexplained weight loss. Because the horse’s stomach continuously produces acid and is designed for foraging, management factors such as intermittent feeding, high-starch diets, and stress from transport or work can contribute to ulcer development. The only way to definitively diagnose gastric ulcers is through gastroscopy, so it’s important to work with your veterinarian if you suspect your horse might have them.

Two veterinarians answer your equine gastric ulcer questions during this archived Ask TheHorse podcast, brought to you by Bimeda.
