Equine Metabolic Syndrome and Laminitis

Equine metabolic syndrome (EMS) is increasingly recognised as a major driver of laminitis, requiring dietary and exercise management.

Key Facts

EMS involves insulin dysregulation, regional fat deposits, and predisposition to laminitis
Ponies, native breeds, and overweight horses are at highest risk
Diagnosis requires blood insulin testing alongside clinical assessment
Dietary management including grass restriction and low-sugar forage is the cornerstone of management
Regular, appropriate exercise improves insulin sensitivity in EMS horses

Welfare Considerations

EMS causes significant welfare harm through recurrent laminitis. Early diagnosis and committed dietary management significantly reduce laminitis frequency and the chronic pain burden for affected horses.

What You Can Do

Test at-risk horses and ponies for EMS with blood insulin testing
Implement strict grazing restrictions for EMS horses, particularly in spring and autumn
Provide low-sugar forage and avoid high-carbohydrate feeds
Develop an appropriate exercise programme with your vet
Monitor body condition carefully and keep EMS horses lean
