Oesophageal obstruction (choke) is a distressing emergency in horses causing food and saliva to accumulate. Most cases resolve with treatment but some require veterinary intervention.
Equine choke causes acute distress from the inability to swallow and the sensation of obstruction. The horse cannot effectively relieve the sensation and becomes increasingly anxious. Antispasmodic medication relaxes the oesophagus and allows resolution in most cases within an hour. Veterinary nasogastric tube flushing is required for persistent obstructions. Prevention includes ensuring horses eat slowly by providing hay before concentrates, soaking pelleted feeds, and addressing dental problems that affect chewing efficiency.
