Do you think your horse may have ulcers? The Equine Specialty Hospital can do a gastroscopy and scope your horse to determine that.
🐴 Glandular vs. Squamous Ulcers: What’s the Difference?
Gastric ulcers are one of the most common health concerns in horses, affecting up to 93% of some populations. However, not all ulcers develop the same way.
Squamous ulcers form in the upper portion of the stomach, which has limited protection against acid. These ulcers are often associated with management factors such as high grain intake, low forage availability, and periods without feed. 🌾
Glandular ulcers occur in the lower portion of the stomach, where protective mechanisms normally defend against acid. These ulcers are more complex and are often linked to breakdowns in these defenses, with risk factors including stress, illness, NSAID use, and disruptions to normal gastric function.
Because these ulcer types have different causes, they may also require different management and treatment approaches. Supporting stomach health starts with:
• Consistent access to forage
• Minimizing starch and large concentrate meals
• Reducing stress and supporting routine
• Working with your veterinarian for proper diagnosis
Signs such as poor performance, weight loss, changes in behavior, or mild recurrent colic should be evaluated to determine the underlying cause.
