Target Keywords: hindgut ulcers horses, right dorsal colitis, horse ulcers but scope clean, hindgut ulcer symptoms Target Audience: Owners whose horse still shows pain signs despite PPI treatment
Veterinary disclaimer: “Hindgut ulcers” is used loosely in owner discussions and can include several problems (colitis, dysbiosis, acidosis, NSAID injury). Work with your veterinarian for diagnosis and a safe plan.
2-Minute Version (Read This First)
1) What is the real problem?
PPIs help reduce stomach acid. If the stomach is not the main driver, a PPI can look like it “does nothing” even if you dosed correctly.
2) Why does it matter?
Some hindgut patterns are worsened by diet and NSAIDs. Treating the wrong compartment wastes time and money.
3) What should you do next?
- Confirm whether this is foregut (EGUS) vs hindgut pattern.
- Review starch exposure and meal timing:
- If your vet mentions mucosal protection, read:
The Classic Situation
You treated ulcers. Maybe you scoped and the vet said the stomach looks clean.
But the horse is still:
- girthy or flank-sensitive
- cranky to brush on the belly
- inconsistent in work
- loose behind (intermittent diarrhea)
That cluster often pushes owners and veterinarians to consider hindgut causes.
Foregut vs Hindgut (Why the Difference Matters)
Foregut (stomach):
- acid-driven environment
- PPIs can be a key tool
Hindgut (cecum/colon):
- fermentation-driven environment
- problems often relate to starch overflow, acidosis, dysbiosis, inflammation, or NSAID effects
This is why “I used omeprazole and nothing changed” is not always a dosing failure.
Common Signs Owners Associate With Hindgut Problems
These are not exclusive, but are common in owner reports:
- right-flank sensitivity
- loose manure or manure water
- performance changes without classic weight loss
- intermittent colic signs
- sensitivity to brushing the belly/flank
If your horse is also showing under-saddle resistance and spookiness, use this symptom checklist:
Why PPIs May Not Help (And Can Look Like They Make Things Worse)
PPIs reduce stomach acid.
But hindgut problems are not primarily a stomach acid problem. In some cases:
- management and diet are the main levers
- mucosal protection strategies may be discussed
- addressing NSAID exposure is critical
What Owners and Vets Commonly Discuss (High Level)
- Diet cleanup (reduce starch hits, stabilize forage)
- Mucosal protection in selected cases
- Re-checking medication tapering and relapse patterns
- Careful evaluation of probiotic claims
Bottom Line
If the stomach looks good but the horse still looks painful, widen the model. Hindgut patterns are real, but they are also a bucket term. The fastest path forward is usually: diet consistency + vet-guided diagnostics and targeted support.
