Horse Gastric Ulcer Monitoring and Long-Term Management

Long-term management of horses with equine gastric ulcer syndrome requires ongoing monitoring, dietary management, and periodic gastroscopy to prevent recurrence and maintain welfare.

Key Facts

Gastric ulcers recur in approximately 75% of horses returned to training without management changes
Omeprazole treatment achieves healing in 60-90% of cases within 28 days
Without addressing underlying management factors, treatment alone is insufficient
Field-based acid buffering products provide short-term relief but do not treat established ulcers
Stress reduction, including reduced stabling, turnout, and stable companionship, reduces ulcer risk

Welfare Considerations

Gastric ulcer long-term management requires treating the cause rather than just the symptom. Horses treated with omeprazole and returned unchanged to the stabling, feeding, and work routine that caused ulcers will re-ulcerate rapidly. The welfare-positive approach combines treatment with genuine management change: increasing turnout, providing continuous forage access, reducing stressors, and managing intensive training schedules. Periodic monitoring gastroscopy — 3-6 monthly in high-risk horses — provides objective evidence of management success or failure. This evidence-based approach is both more humane and more economically rational than repeated treatment cycles without addressing root causes.

What You Can Do

Implement management changes alongside omeprazole treatment — treatment without change is temporary
Provide continuous forage access through ad-lib hay or slow feeders
Schedule periodic gastroscopy to monitor healing and recurrence objectively
Discuss with your vet which management factors are most relevant for your specific horse
Consider stable companionship as a stress reduction measure if horses are housed alone
