Summary
# Editorial Summary: Equine Metabolic Syndrome and Genetic Complexity Equine metabolic syndrome represents a significant welfare and performance concern in modern practice, chiefly because of its strong association with laminitis and the resulting lameness that often ends athletic careers. Stefaniuk-Szmukier and colleagues conducted a comprehensive review synthesising current understanding of EMS aetiology, with particular emphasis on the multifactorial genetic influences alongside environmental triggers, diagnostic approaches, and therapeutic options. The syndrome manifests as a constellation of clinical signs—regional or generalised obesity, bilateral lameness, and characteristic hoof rings indicating previous laminitis episodes—underpinned by insulin dysregulation that disrupts normal glucose, insulin and lipid homeostasis. Whilst dietary management and conditioning programmes remain the cornerstone of EMS control, the authors highlight emerging regenerative medicine approaches that may offer adjunctive therapeutic benefits beyond traditional interventions. For farriers, veterinarians and other equine professionals, this synthesis underscores that EMS management requires a multidisciplinary approach recognising both genetic predisposition and modifiable environmental factors, with early metabolic screening and weight control as critical preventative strategies to mitigate laminitis risk.

Practical Takeaways
- •Recognize EMS early by looking for obesity, local fat deposits, bilateral lameness, and characteristic hoof rings—these warrant insulin/glucose testing
- •Manage affected horses through strict diet control and consistent fitness work; medication and regenerative therapies are not yet standard protocols
- •Understand that laminitis secondary to EMS is a major performance-limiting consequence, making prevention and early intervention critical for owners
Key Findings
- •EMS is a multifactorial genetic disease linked to insulin dysregulation affecting glucose, insulin and lipid metabolism
- •Clinical presentation includes obesity, local fat deposition, bilateral lameness, and hoof rings indicating current or previous laminitis
- •Management is primarily based on dietary control and fitness discipline, with regenerative medicine approaches under investigation
- •EMS has become increasingly important in modern veterinary medicine and is frequently performance-terminating due to laminitis complications
