Horse Endocrine Metabolic Disease Welfare

Pituitary pars intermedia dysfunction (PPID) and equine metabolic syndrome (EMS) cause painful laminitis and systemic disease in horses, with management improving quality of life significantly.

Key Facts

PPID affects an estimated 15-21% of horses and ponies over 15 years of age
Both PPID and EMS predispose horses to recurrent laminitis through insulin dysregulation
Pergolide medication for PPID is highly effective in controlling clinical signs
Dietary management limiting non-structural carbohydrates is essential for EMS horses
Body condition scoring and pituitary testing allow early diagnosis before laminitis develops

Welfare Considerations

PPID and EMS cause painful laminitis episodes that are largely preventable with early diagnosis and management. Regular health monitoring of older equids is essential.

What You Can Do

Test horses over 15 years for PPID annually, especially those showing coat change or muscle loss
Manage grazing access carefully for horses with insulin dysregulation or EMS
Seek veterinary treatment promptly for any signs of laminitis
Provide appropriate dietary management to prevent excessive insulin responses
