Gastrointestinal examination

Proper feed intake is essential for sport horses to perform at their best. Disorders of the stomach or intestines can interfere with this process. Gastric ulcers, for example, are common in sport horses. At the Sporthorse Medical Diagnostic Centre (SMDC), we offer advanced gastrointestinal examinations performed by a Diplomate of the European College of Veterinary Sports Medicine and Rehabilitation (ECVSMR).

Indications for a gastrointestinal examination

  • Poor performance
  • Weight loss and/or reduced appetite
  • Poor coat condition and/or abnormal manure
  • Behavioral changes in the stable (teeth grinding, yawning)
  • Behavioral changes during work (reaction to saddling or girthing, resistance during exercise)
  • Recurrent colic
  • Lack of energy

Contents of the examination

The clinical examination is the first step in evaluating the horse’s gastrointestinal system. The examination is performed by a European specialist (Diplomate ECVSMR) and may include several components.

Gastroscopy

During a gastroscopy (or “gastric endoscopy”), the stomach lining is carefully examined using a camera to identify ulcers or other mucosal abnormalities. This allows us to determine not only the presence of gastric ulcers but also their exact location and severity. Distinguishing between the following types of lesions is essential, as their causes, treatments, and prognoses differ:

  • Squamous gastric ulcers (in the upper, non-glandular part of the stomach)
  • Glandular gastric ulcers (in the lower, glandular part of the stomach)

During the examination, the esophagus (esophagoscopy) and, in most cases, the first part of the duodenum (duodenoscopy) can also be visualized.

Biopsies

If needed, a biopsy of the stomach or intestinal wall can be taken during the gastroscopy for further laboratory analysis. The sampling process is not uncomfortable for the horse and allows for a detailed microscopic evaluation of the mucosal structure.

Ultrasonography

If abdominal organ disorders are suspected and the gastroscopy does not provide a clear diagnosis, an abdominal ultrasound can be performed. This allows visualization of structures such as the stomach, liver, spleen, and intestines.

Same-day results available

The results of the examination are usually discussed immediately afterward. Based on the findings, a targeted treatment plan is created, often including medication (such as acid inhibitors), dietary adjustments, and management recommendations.

An accurate diagnosis prevents unnecessary medication, speeds up recovery, and contributes to long-term well-being and performance.

The findings are documented in a written report and discussed with the owner and, when applicable, the referring veterinarian. Through specialist expertise, advanced equipment, and multidisciplinary collaboration, we provide a reliable assessment and effective treatment recommendations for all types of cardiac conditions.
