What Are the Causes of Gastric Ulcers in Horses?

According to the Tufts Cummings School of Veterinary Medicine, seventy to one hundred percent of sport horses may have evidence of the stomach erosion associated with gastric ulcers. Symptoms include frequent colic, limited appetite and overall poor condition. An endoscopic exam is the only way to be certain that your horse is suffering from an ulcer.

  1. Confinement

    • Stall confinement is one of the leading causes of ulcers in horses. Restricted movement, especially while feeding, can cause ulcers.

    Feeding Schedule

    • Stomach acids can develop quickly when your horse is not eating. Limited feedings and spoiled food can cause ulcers.

    Stress

    • Stress in all its forms increases the likelihood of ulcers. Isolation, tailoring and herd changes can increase your horse's chance of developing an ulcer.

    Diet

    • High energy concentrates can increase the amount of stomach acid that your horse produces. It does not contain enough roughage to stimulate acid-reducing saliva production.

    Medications

    • Certain medications--especially NSAIDs like Bute and Banamine--can cause ulcers. Ulceration occurs when these products are used for extended periods or at improper dosages.

    Treatment

    • In addition to the management changes mentioned above, there are medications available to treat ulcers. Speak to your veterinarian about the best protocol for your horse.
