What is the Common Cause of Gastric Ulcers in Horses?

One of the most common causes of gastric ulcers in horses is stress. When a horse is under stress, its body produces more acid, which can lead to the development of ulcers. There are many different types of stress that can trigger ulcer development, including physical stress from exercise, mental stress from competition or training, and emotional stress from changes in environment or routine.

Managing stress levels is an important part of preventing gastric ulcers in horses. Other potential causes of gastric ulcers include certain medications (such as corticosteroids), infections, and genetic predisposition.

What Percentage of Racehorses Have Ulcers?

According to a study conducted by the University of Liverpool, it was estimated that 60% of racehorses have ulcers. However, this number could be higher as many horses go undiagnosed. Ulcers are caused by stomach acid and can lead to weight loss, colic, poor performance and behavioral changes.

If left untreated, ulcers can be fatal. Racehorses are more susceptible to developing ulcers due to the high levels of stress they undergo. Factors such as travel, racing and training can all contribute to the development of ulcers.

Treatment for ulcers typically involves medication and management changes such as diet modification and reduced exercise.

Which One is the Most Common Site for Formation of Gastric Ulcer in Horse?

Gastric ulcers are a common condition in horses, with an estimated prevalence of 60-90% in adult performance horses. While ulcers can form in any part of the gastrointestinal tract, they are most commonly found in the squamous epithelium lining the non-glandular (fundic) region of the stomach. This is due to the fact that this area is exposed to the highest levels of acid and pepsin, which can irritate and damage the mucosal barrier.

The risk factors for developing gastric ulcers include stress, poor nutrition, medication (such as NSAIDs), and exercise. While there are many possible treatments for gastric ulcers, prevention is often the best approach. Some simple management practices that can help reduce the risk of ulcers include providing a consistent routine, minimizing stressors, feeding small meals frequently throughout the day, and avoiding excessive grain or concentrate intake.

What Percent of Performance Horses Might Have Gastric Ulcers at Some Point in Their Lives?

Gastric ulcers are a common issue in performance horses, with an estimated prevalence of 60-90% in adult horses. There are many factors that contribute to the development of gastric ulcers, including stress, diet, exercise, and medication use. While ulcers can occur in any horse, those that are under constant stress or in training are at a higher risk.

Signs of gastric ulcers include poor appetite, weight loss, behavior changes, and decreased performance. If left untreated, gastric ulcers can lead to more serious health problems such as colic or perforation of the stomach wall. Treatment options include dietary changes, medication, and rest.

With proper management, most horses with gastric ulcers can return to normal function.


A new study has found that gastric ulcers are common in New Zealand racehorses. The study, which was conducted by the University of Auckland, looked at 100 racehorses and found that 60% of them had gastric ulcers. The study also found that horses with gastric ulcers were more likely to have a poorer performance than those without.

This is likely because the ulcers can cause pain and discomfort, which can affect a horse’s ability to concentrate and perform at its best. If you have a horse in training, it is important to have it checked for gastric ulcers and to treat them if present. There are various treatments available that can help to heal the ulcers and improve your horse’s performance.
