⭐⭐ Monthly Theme Continued - Signs of Gastric Ulceration ⭐⭐
Gastric ulcer disease in horses can present in a wide variety of ways:
- Girthiness or grumpiness
- Resentment of being groomed
- Reluctance to work
- Unwillingness to jump
- General reduction in performance
- Reduction in appetite
- Weight loss
- Poor hair coat
- Tooth grinding
- Colic signs (a rare symptom)
- Subtle non-specific signs ‘just not quite themselves’
We also find that if we gastroscope horses with no perceived problem as part of a pre-season ‘fitness to work’ routine examination, that significant ulcers may be present. If we treat these horses, it is often then reported that their level of performance increases. EGUS may therefore be performance limiting without resulting in any specific clinical signs, even in horses and ponies considered to be working well.
Large scale studies have concluded that gastric ulcer disease is present in up to 90% percent of performance horses and more than 50% of ponies, affecting all ages, breeds and types and horses and ponies living under all management systems.
Foals are also prone to gastric ulcers and signs in foals and youngstock can be much more severe, including signs of colic, excess salivation, tooth grinding, reduced nursing and diarrhoea.
Next Monday we will look into Gastrosopy.
