## Overview Equine gastric ulcer syndrome (EGUS) encompasses ulceration of the squamous (upper) and glandular (lower) stomach lining. It is extremely common in performance horses. Risk factors include high-grain diets, intermittent feeding, stress, and intense training. Many horses show subtle or no outward signs. ## Causes Acid exposure of unprotected squamous mucosa, plus impaired glandular defenses. Management and stress factors predominate. ## Diagnosis Gastroscopy is required for definitive diagnosis and grading. ## Treatment Omeprazole is the primary acid-suppressing medication. Management changes (forage availability, reduced grain, stress reduction) are essential for healing and prevention. ## Recovery and Prognosis Good with appropriate medication and management. Recurrence is common if risk factors persist. ## Prevention Maximize forage, minimize grain boluses, and reduce stressors. Low-dose omeprazole can be used preventively in high-risk horses.
poor appetite; poor body condition; recurrent mild colic; girthiness; behavioral changes; teeth grinding; many horses are asymptomatic
