Equine Gastric Ulcer Syndrome (EGUS)
GastrointestinalEquineNew
Key Points
  • Equine gastric ulcer syndrome (EGUS) is an umbrella term, describing erosions and ulcers affecting the equine stomach
  • There are two forms: equine squamous gastric disease (ESGD) and equine glandular gastric disease (EGGD)
    • Each affects a different stomach region and has different underlying mechanisms, risk factors and treatment approaches
  • ESGD is associated with exposure of the squamous mucosa to stomach acid whereas EGGD is associated with a failure of normal glandular mucosal defence mechanisms
  • Clinical signs are often subtle, intermittent and non-specific so EGUS can be under-recognised
  • Definitive diagnosis requires visualisation of the gastric mucosa via gastroscopy
  • Proton pump inhibitors (PPIs) and other gastroprotectants are key for medical management but must be combined with management changes
  • Maximising forage access, reduced fasted periods, minimising stress and managing intense training effectively are all essential for prevention
