If you suspect your horse has ulcers, the first step is to contact your veterinarian check for horse ulcers. They are the only ones who can properly examine your horse and confirm a diagnosis, as many signs of equine gastric ulcer syndrome symptoms look like other health issues.
Deciphering Equine Gastric Ulcer Syndrome Symptoms
Stomach problems are common in horses. They can cause real pain. Recognizing the signs early is key to helping your horse feel better quickly. These problems often involve sores in the stomach lining. This condition is known as Equine Gastric Ulcer Syndrome (EGUS).
Common Signs of Gastric Ulcers
Many different things can point toward your horse having ulcers. Some signs are very obvious. Others are subtle. You must watch your horse closely every day.
Direct Physical Signs
Some symptoms show up right away. These are often related to pain when the stomach acid moves.
- Poor Appetite: A classic sign is appetite loss in horses with ulcers. Your horse may pick at food. He might leave his normal feed in the bucket.
- Weight Loss: Even if your horse eats some, he might lose weight. This happens because he feels too sore to eat much or doesn’t absorb nutrients well.
- Girthiness or Sensitivity: When you groom your horse’s belly area, he might react. He might flinch, pin his ears, or try to snap. This area is called the girth area.
- Poor Coat Condition: A dull, rough coat often signals an internal issue. Ulcers stop the horse from getting the good nutrition needed for a shiny coat.
Changes in Behavior and Performance
Ulcers cause chronic pain. This pain changes how your horse acts and performs during work.
- Reluctance to Work: Your horse might seem “off.” He may not want to move forward. He might resist the bit or seem grumpy under saddle.
- Lying Down Frequently: Horses with severe stomach pain often lie down more than normal. They may try to lie down right after eating. This is an attempt to ease the stomach discomfort.
- Teeth Grinding (Bruxism): Some horses grind their teeth when in pain. This noise is a strong indicator of distress.
- Excessive Salivation or Drooling: You might see foamy saliva or excessive drooling during riding or even while standing.
Distinguishing Between Colic and Ulcers
People often confuse general belly aches with ulcers. Knowing the difference between colic vs ulcers in horses is important for quick action.
Colic is a broad term for abdominal pain. It can be caused by many things: gas buildup, twisted guts, or impacted feed. Colic usually comes on suddenly and is severe. A horse in acute colic might roll, look at its flank, or sweat heavily.
Ulcers, however, are often a chronic, low-grade pain. The signs build up slowly over weeks or months. While severe ulcers can trigger a true colic episode, the typical stress ulcer symptoms in horses are more about consistent mild discomfort and poor overall health rather than sudden, violent pain. If your horse has mild, recurring aches, think about ulcers first.
Fathoming Hindgut Issues: Signs of Hindgut Ulceration
It is not just the stomach that can get sores. Many horses develop ulcers in the lower part of the digestive tract. These are called hindgut ulcer signs in horses. These sores are in the large colon and cecum.
Why Hindgut Ulcers Happen
Hindgut ulcers often happen because of diet and stress, just like stomach ulcers. If a horse gets too much grain or not enough forage (hay/grass), the hindgut environment becomes too acidic. This acid eats away at the lining.
Unique Signs of Hindgut Trouble
The symptoms of hindgut ulcers can be trickier to spot than stomach ulcers. They often mimic general poor health.
- Chronic Low-Grade Colic: Horses with hindgut ulcers frequently have mild gut upset. They might paw, seem restless, or shift weight often. These are not the dramatic signs of a true colic, but constant signs of annoyance.
- Changes in Feces: You might notice changes in manure consistency. It could be very soft, or you might see undigested feed particles in the droppings.
- Poor Performance Under Saddle: Because the large colon sits close to the back, pain here can severely affect the horse’s willingness to engage the hindquarters or move forward freely.
- Empty Stalls: A horse might refuse to lie down comfortably, preferring to stand most of the time.
Recognizing Stomach Ulcers in Horses: A Closer Look
To properly start recognizing stomach ulcers in horses, we need to look at the main risk factors. Knowing why they happen helps you see the signs more clearly.
Factors Leading to Gastric Ulcers
The horse’s digestive system is designed for continuous grazing. When this natural pattern is broken, problems start.
| Factor | Effect on Stomach | Common Symptoms Associated |
|---|---|---|
| High-Grain Diets | Rapidly lowers stomach pH after feeding. | Appetite loss, mild discomfort. |
| Infrequent Feeding | Stomach produces acid constantly, but no food buffers it. | Pacing, teeth grinding. |
| Intense Exercise | Physical pressure on the stomach, acid splash-back. | Poor performance, resistance. |
| Stress (Travel, Isolation) | Triggers hormones that increase acid secretion. | Behavior changes, stress ulcer symptoms in horses. |
| NSAID Use (e.g., Bute) | Directly damages the stomach lining. | Acute pain, severe appetite loss. |
Subtle Horse Behavioral Signs of Ulcers
Behavioral changes are often the earliest clue that something is wrong internally.
- Grooming Issues: A horse that suddenly stops wanting to be groomed or is very sensitive when saddled might be protecting a sore abdomen.
- Changes in Social Behavior: A usually friendly horse might become grumpy or withdrawn. Pain makes animals irritable.
- Fore-Soreness Mimicry: Sometimes, the pain is so generalized that owners think the horse is sore in the back or stifles when the issue is actually in the gut.
- Yawning Excessively: Frequent, deep yawning, especially when not tired, can be a sign of stomach discomfort or acid reflux.
The Path to Certainty: Diagnosis of Equine Gastric Ulcers
If you see several of the above signs, the next step is getting confirmation. You cannot treat ulcers effectively without a definite diagnosis of equine gastric ulcers.
Why a Veterinarian Check is Essential
Self-diagnosing can lead to using the wrong treatment or delaying care for a more serious issue. A veterinarian will take a full history of your horse’s feeding, training, and environment.
Steps a vet takes:
- Physical Exam: Checking the horse’s body condition, coat, and signs of discomfort.
- Symptom Review: Discussing when the symptoms started and what makes them better or worse.
- Rule Out Other Issues: Performing blood work or checking teeth to rule out infections or dental problems that also cause weight loss or attitude changes.
The Gold Standard: Gastroscopy
The best way to confirm stomach ulcers is through gastroscopy. This procedure is crucial for accurate diagnosis of equine gastric ulcers.
- What Happens: The horse is gently sedated. A flexible tube with a camera (endoscope) is passed down the esophagus and into the stomach.
- What It Shows: The vet can directly view the stomach lining. They can see the exact number, size, and location of any ulcers. This helps determine the severity.
- Location Matters: Gastroscopy clearly shows if ulcers are in the glandular area (more serious) or the non-glandular area (common in sport horses).
Hindgut ulcers are harder to see, as the scope cannot easily reach deep into the small colon. Diagnosis for hindgut issues often relies more heavily on response to treatment trials and ruling out other diseases.
Developing a Plan: Gastric Ulcer Treatment for Horses
Once the vet confirms EGUS, treatment begins immediately. Successful gastric ulcer treatment for horses involves two parts: healing the sores and preventing them from coming back.
Medications to Heal Ulcers
The main goal is to reduce the amount of acid hitting the sores.
- Proton Pump Inhibitors (PPIs): Medications like omeprazole are very effective. They strongly block the stomach’s acid pumps. This allows the lining time to heal. These are usually given for several weeks.
- H2 Blockers: Drugs like ranitidine reduce the amount of acid released. These are sometimes used for milder cases or alongside PPIs.
- Mucosal Protectants: Medications such as sucralfate coat the ulcers. This creates a barrier against the acid, offering immediate, temporary relief while other drugs work.
Dietary and Management Changes
Medication alone is not enough. The environment that caused the ulcers must change. This is vital for long-term success.
- Increase Forage: Feed hay or grass constantly. The horse should have access to forage almost 24 hours a day. The chewing action produces saliva, which is a natural antacid.
- Limit Intense Exercise: If the horse is in heavy training, the vet might suggest a temporary reduction in work intensity. This reduces the splashing of acid during strenuous activity.
- Reduce Concentrates: Lower the amount of grain or sweet feed. Switch to high-fiber, high-fat feeds if extra calories are needed.
- Stress Management: This is key for treating stress ulcer symptoms in horses. Try to keep routines consistent. Minimize long periods of isolation. Use slow feeders to make eating last longer.
Special Focus: Stress and Ulcers
Horses are herd animals, and they thrive on routine. Any break in that routine can cause major internal stress. This stress directly leads to ulcers, hence the term stress ulcer symptoms in horses.
Identifying Stressors
What stresses your horse? Think about:
- Moving to a new barn.
- Long periods of stall rest.
- Intense competition schedules (trailer rides, new arenas).
- Being separated from companions.
- Sudden changes in feeding times.
When you see signs like restlessness, pacing, or sudden moodiness after a stressful event, link it back to potential gut pain.
Managing Chronic Stress
Treating stress-related ulcers requires lifestyle adjustments alongside medication.
- Social Contact: Ensure your horse has visual, and ideally physical, contact with other horses.
- Turnout Time: Maximize daily turnout time, even if it’s just a small paddock. Movement helps digestion.
- Environmental Enrichment: Provide toys or browse opportunities if the horse is stalled frequently. Keep their minds busy.

Frequently Asked Questions (FAQ)
Can I treat my horse’s ulcers just with diet changes?
While diet is essential for managing and preventing ulcers, most confirmed cases require medical intervention, like PPIs, to heal existing severe sores. Diet changes alone are rarely enough to cure established ulcers.
How long does it take for ulcer treatment to work?
Most horses show improvement in attitude and appetite within 3 to 7 days of starting proper medication. Complete healing of the stomach lining usually takes 4 to 6 weeks, depending on the severity seen during gastroscopy.
Are ulcers contagious between horses?
No, ulcers are not contagious. They are caused by an imbalance of stomach acid, diet, stress, or physical damage (like NSAIDs), not by germs passed from one horse to another.
How often should I get a veterinarian check for horse ulcers?
If your horse has been successfully treated, your vet might recommend a re-check or scope after the treatment period ends to confirm healing. For management, consistent observation of behavioral changes is your best tool between annual check-ups.
What is the difference between squamous and glandular ulcers?
Squamous ulcers occur in the upper part of the stomach (foregut), which is not protected by bicarbonate. Glandular ulcers occur in the lower part of the stomach, which is normally acidic. Glandular ulcers are often harder to treat effectively because the normal treatment drugs do not work as well in that area.
