Gastric ulcers are common in horses and may show up as poor appetite, attitude changes, girth sensitivity, decreased performance, weight loss, or mild/recurrent colic.
How do we know?
Gastroscopy is the most accurate way to diagnose ulcers. A small camera allows your veterinarian to look inside the stomach and determine if ulcers are present and how severe they are.
Treatment: GastroGard® (omeprazole) is commonly used to treat gastric ulcers by reducing stomach acid and allowing the stomach lining to heal.
Prevention matters, too. Plenty of forage, minimizing long periods without food, reducing stress, turnout when possible, and thoughtful feeding and training routines can all help reduce ulcer risk. For horses at higher risk during travel, showing, or other stressful periods—your veterinarian may also recommend preventative omeprazole.
