Horse Gastric Ulcer Advanced Prevention: Evidence-Based Protocols

Advanced prevention of equine gastric ulcer syndrome uses evidence-based feeding, management, and exercise protocols to address root causes rather than relying on ongoing medication.

Key Facts

Equine Squamous Gastric Disease affects 50-90% of sport horses in active training
The stomach produces acid continuously — forage buffers acid and reduces ulcer risk through saliva production
Withholding forage for more than 6 hours is the single strongest modifiable risk factor for squamous disease
Exercise on an empty stomach increases acid splash to the squamous region — small forage meals before work reduce risk
Omeprazole (GastroGard) treats but does not prevent recurrence without management change
Gastroscopy remains the gold standard for diagnosis — clinical signs alone have poor diagnostic accuracy

Welfare Considerations

Equine gastric ulcer syndrome is largely a management-created disease in which the stabling, feeding schedules, and work patterns of modern horse management produce near-universal disease in sport horse populations. The welfare implications are significant — gastric pain affects mood, performance willingness, and quality of life. Prevention through feeding management is demonstrably more effective and far less expensive than repeated treatment cycles. The central message from equine gastroenterologists is that forage provision — not medication — is the primary prevention tool.

What You Can Do

Ensure horses always have access to forage — never leave hay gaps exceeding 4-6 hours
Provide a small hay meal before exercise to reduce acid splash to the squamous mucosa
Discuss gastroscopy with your vet before assuming behavioral changes are training problems
Implement evidence-based prevention protocols before using omeprazole as a management band-aid
