Summary
# Editorial Summary: Field Treatment and Management of Endocrinopathic Laminitis Endocrinopathic laminitis—primarily driven by equine metabolic syndrome and pituitary pars intermedia dysfunction—presents a particular clinical challenge because structural damage to the foot can progress substantially before lameness becomes obvious to owners or handlers. Walsh's 2010 review emphasises that early detection of hyperinsulinaemia through appropriate diagnostic testing and rapid implementation of dietary, pharmaceutical and management controls are essential to prevent irreversible lamellar failure. The practical takeaway for field-based professionals is clear: intervention must be proactive rather than reactive, focusing on identifying at-risk individuals (particularly overweight horses, those with abnormal fat distribution, and older animals) and controlling insulin dysregulation before clinical laminitis develops. Strategies include strict grazing management and diet modification to reduce non-structural carbohydrate intake, weight loss protocols, and judicious use of medications such as levothyroxine or metformin depending on the underlying endocrine dysfunction. Shifting practice from managing acute laminitis episodes to preventing them altogether through vigilant screening and early intervention offers the most favourable outcomes for soundness and reduces both animal suffering and client expense.

Practical Takeaways
- •Screen horses and ponies for hyperinsulinemia before laminitis develops clinically, as subclinical disease causes progressive foot damage
- •Implement early intervention strategies targeting insulin control rather than waiting for lameness to appear
- •Counsel owners that prevention through management is more beneficial and cost-effective than treating established laminitic changes
Key Findings
- •Endocrinopathic laminitis causes extensive foot damage before clinical signs become apparent
- •Early diagnosis and control of hyperinsulinemia are critical to prevent crippling changes
- •Prevention of endocrinopathic laminitis is more effective than treatment after disease onset
