Summary Two common endocrine disorders, pituitary pars intermedia dysfunction and equine metabolic syndrome, predispose horses and ponies to laminitis and may even induce the condition. The exact mechanisms involved in endocrinopathic laminitis have not been elucidated but hyperinsulinaemia and insulin resistance are currently being investigated. Obesity and regional adiposity may also contribute to laminitis susceptibility through the release of inflammatory cytokines and adipokines. In the case of pituitary pars intermedia dysfunction, glucocorticoid excess is likely to weaken hoof structures, alter vascular dynamics within the foot and induce or exacerbate insulin resistance. This review will summarise current theories regarding the pathophysiology of endocrinopathic laminitis and provide recommendations for the diagnosis and management of these common equine endocrine disorders.
