Pituitary pars intermedia dysfunction

Pituitary pars intermedia dysfunction (PPID), or equine Cushing's disease, is an endocrine disease affecting the pituitary gland of horses. It is most commonly seen in older animals,[1] and is classically associated with the formation of a long, wavy coat (hirsutism) and chronic laminitis.

Cushing's disease commonly causes hirsutism, muscle wasting along the top line, and abnormal fat distribution.
