It is believed that dietary composition, stress, and intensive exercise all result in ulcers in horses.  These ulcers can be uncomfortable, resulting in loss of appetite. Horses are seen to constantly grind their teeth when they have ulcers. Equine digestive ulcers can be fatal especially to younger horses. While a permanent damage can happen among adult horses. If these ulcers are not treated, it may even cause death.

Development of Ulcers

Horses develop ulcers in many ways through the management of the owners. The condition, therefore, is mainly caused by man. The contributory factors for such condition include fasting, high-grain, starchy meals, stable confinement, insufficient forage, intensive exercise, and long-term treatment with NSAIDs.

Avoiding the contributory factors can help prevent ulcer formation. However, they might be impractical most of the time. However, you can turn things around by giving more forage-based diet and allowing your horse to graze freely as much as possible. If you have to use stables, be sure they are horse-friendly. Fasting is probably the most common factor of ulcer formation since the horse’s stomach continuously secretes acid with or without the presence of food. This acid will buildup when the stomach is empty and then the corrosive nature of the acid can destroy the stomach lining ultimately leading to horse ulcers. Do not leave your horse without access to food and do not allow them to fast beyond a couple of hours in that case.


Treating horse ulcers is rather simple. It is just a matter of allowing your horse to graze once in a while and get enough rest from exercise. Alternatively, many horse owners make use of drugs which act by suppressing acid production like Omeprazole. Treatment with such drug can be expensive considering you don’t need only one dose to eradicate ulcers effectively. You need about a month-long therapy course for horse ulcers to be treated.
