Horse Gastric Ulcer Monitoring and Long-Term Management

Gastric ulcers in horses have a high recurrence rate when root causes are not addressed. Monitoring approaches and long-term management strategies enable sustainable welfare improvement for susceptible horses.

Key Facts

ESGD recurrence rates after omeprazole treatment are 80%+ if management changes are not implemented alongside medication
Gastroscopy is the only definitive diagnostic tool for ESGD and EGGD (equine glandular gastric disease)
Treatment duration for ESGD is typically 28 days; EGGD (glandular disease) often requires 8-12 weeks of treatment
Sucralfate provides additional mucosal protection specifically for glandular disease when combined with omeprazole
Feed management changes (hay before exercise, ad libitum forage access) reduce recurrence rates significantly
Stress reduction — competition pressure, transport, training intensity — reduces ulcer recurrence in susceptible horses

Welfare Considerations

The welfare management of gastric ulcers requires accepting that management change is not optional — it is the treatment. Omeprazole without management change achieves temporary symptom relief followed by rapid recurrence when medication stops. Each recurrence cycle causes additional ulcer-related discomfort and requires additional medication. The horse who is treated with omeprazole and appropriate management changes achieves mucosal healing and, if changes are maintained, significantly lower recurrence risk. The welfare obligation of the horse owner is to implement the management changes that address root causes, even when those changes create inconvenience or require adjustment to training and competition schedules. The horse's gastric pain is the measure of whether management changes are adequate.

What You Can Do

Implement management changes alongside any omeprazole treatment: ad libitum hay, forage before exercise, stress reduction
Request gastroscopy for definitive diagnosis rather than treating empirically — knowing the ulcer grade and location guides treatment
Complete the full treatment course and request repeat gastroscopy to confirm healing before stopping medication
Maintain forage access and reduce fasting periods as the primary long-term prevention strategy
Monitor for recurrence signs — behavioral changes, girthiness, poor performance — and arrange prompt re-evaluation rather than waiting for obvious deterioration
