Gastric Ulceration

Gastric ulceration in horses is remarkably similar to the condition found in humans, characterised by erosions of the stomach lining due to the corrosive effects of stomach acid. It has only been in recent years that the prevalence of this condition in horses has been fully understood. Studies indicate that an astonishing 70-100% of horses can be affected by gastric ulcers at some point, with the condition being particularly prevalent among sport horses and racehorses in active training.

What Causes Gastric Ulceration?

The equine stomach naturally contains high levels of acids and digestive enzymes, which are potent enough to break down the stomach lining. However, the stomach is equipped with protective mechanisms to prevent this from happening. Gastric ulceration occurs when these protective mechanisms are overwhelmed by the acids and enzymes, leading to damage and erosion of the stomach lining. This imbalance can be triggered by various factors, disrupting the delicate equilibrium that normally protects the stomach.

What Are the Signs of Gastric Ulceration?

The symptoms of gastric ulceration in horses can be quite subtle and may easily go unnoticed. Affected horses often exhibit lethargy, poor performance, a decreased appetite, weight loss, and may experience recurrent bouts of colic. In foals, the signs tend to be more severe, with frequent colic episodes and the potential development of diarrhoea. The discomfort caused by gastric ulcers often leads foals to grind their teeth and salivate excessively, both of which are telltale signs that should not be ignored.

How Can I Prevent Gastric Ulceration?

Several factors can increase the risk of your horse developing gastric ulcers, including stress, diet, exercise, and certain medications. Each of these factors can contribute to an environment where the stomach’s protective mechanisms are compromised. It is crucial to manage these aspects carefully, and your veterinary surgeon will be able to provide you with tailored advice on how to mitigate these risks effectively. By addressing these factors, you can help maintain the delicate balance within your horse’s stomach and reduce the likelihood of ulceration occurring.
