Gastric Ulcers in Horses

Gastric Ulcers in Horses

EGUS – EQUINE GASTRIC ULCER SYNDROME IS DIAGNOSED AS EITHER:

ESGD – Equine Squamous Gastric Disease
EGGD – Equine Glandular Gastric Disease

Equine Squamous Gastric Disease (ESGD)

  • Affects the upper, non-glandular or squamous region of the stomach
  • Measured on a scale of 1-4
  • Occur in response to risk factors inherent in domestication and intensive management
  • Result of prolonged exposure to the normal hydrochloric acid in the stomach
  • Can be secondary to EGGD
  • Only identified via endoscopy

 Risk Factors

  • Busy competition/travelling schedules
  • Exercising with an empty stomach
  • Gastric compression, caused by increased intra-abdominal pressure
  • Changes to routine
  • Low forage, high concentrate diets
  • Intensive training
  • Early weaning
  • Non-steroidal anti inflammatory drugs (NSAIDs)

Ongoing Management

  • Use of an acid buffer such as Maxia Complete or Maxia Digest
  • Omeprazole products
  • Fibre pre exercise
  • Low starch – high fibre diets
  • Feeding little and often
  • Preparing for stressful situations


Equine Glandular Gastric Disease (EGGD)

  • Affects the lower, glandular or pyloric region of the stomach
  • Measured on a scale of 1-4
  • Cause is more complex than ESGD
  • Can be the result of a breakdown of protective factors, primarily Mucas
  • Usually slower to heal and can require prolonged/multiple treatments
  • Only identified via endoscopy

Risk Factors

  • High intensity exercise more than 5 times per week
  • Breed – show jumping warmbloods are a high risk
  • Stress
  • More than 3 riders
  • Non-steroidal anti inflammatory drugs (NSAIDs)

Ongoing Management

  • Use of an acid buffer such as Maxia Complete or Maxia Digest
  • Omeprazole products in combination with sucralfete
  • Identify triggers
  • Improving mucus quantity/quality
  • Rest days – at least 2 x per week
  • Minimise caregivers/riders
  • Low starch diet
