Gastric ulcers in horses

Research has shown that more horses than expected suffer from gastric ulcers. That has an effect on their performance. If a horse cannot chew enough on fiber-rich roughage, too little saliva is produced. This is necessary for reducing the acidity in the stomach. Stress has an effect on the development of stomach ulcers. For sport horses traveling to competitions and staying in a strange environment enhances stress.

It is impossible to see from the outside if a horse has gastric ulcers. This can only be done with a gastroscopy, a small camera at the end of a long hose that goes into the stomach. This examination can be done at home in the stable.

Gastroscopy is the only reliable method for identifying gastric ulcers in horses. The entire stomach, including pylorus and the proximal duodenum, should be included in the study, as lesions in these regions can easily be missed.
