Gastroscopy

A gastroscope is a procedure for diagnosing gastric ulcers in horses. Performed under sedation, it involves the insertion of a 3-meter scope through the horse's nostrils and into the stomach. This procedure grants us a direct view of the stomach lining, enabling us to detect the presence and the location of ulcers.

This precise diagnosis is pivotal in determining the most effective treatment strategies for your horse.

To prepare for the gastroscope, it is imperative that the horse is fasted for a minimum of 16 hours before the procedure and kept in a stable overnight without any edible bedding. These pre-procedure measures are essential to ensure the accuracy and success of the examination, ultimately leading to the best possible outcome for your horse's health.

Horses' stomachs have two distinct linings, squamous and glandular, both susceptible to different types of ulcers with distinct causes and treatments.

Squamous ulcers primarily affect the upper part of the stomach and are typically a result of stomach acid splashing onto this region.
Glandular ulcers, sometimes called pyloric ulcers, occur in the lower part of the stomach due to the failure of protective mechanisms against stomach acid, often concentrated around the pylorus.

Recognising signs of ulcers in horses is crucial which include changes in behaviour, girth sensitivity, weight loss, altered appetite, colic signs and diminished performance.

Several factors can contribute to these ulcers, such as prolonged forage deprivation, high-starch diets, intense exercise and stress.

Diagnosis is facilitated through a gastroscope, allowing for precise identification of ulcer type and location.

Treatment Options:

Oral Omeprazole: This is the primary treatment for squamous ulcers. It effectively reduces stomach acid production, alleviating the condition.
Injectable Omeprazole: Injectable omeprazole can be utilised for treating glandular ulcers, offering an alternative to the oral form for this specific type.
Sucralfate: Often used alongside other treatments, sucralfate aids in the healing process of ulcers by forming a protective barrier over the affected areas.
Misoprostol: Research has shown that misoprostol can be effective against glandular ulcers, providing another option for treatment in these

Prevention is key with strategies including increased turnout, ample forage and roughage, supplementing feed with oil, avoiding extended periods without feed and providing hay or chaff 30 minutes before exercise. These measures collectively ensure the well-being of your horse's digestive health.
