Days in Horse Country – Cushing’s
Syndrome
Equine
Cushing’s Syndrome used to be called Cushing’s Disease. Cushing’s Syndrome is even more accurately
labeled pituitary pars intermediary dysfunction (PPID). This condition occurs when a portion of the
pituitary gland becomes unable to function properly. The ACTH hormone and blood cortisol levels are
chronically too high. Horses with this
condition, who are often older, may also be insulin resistant.
You can tell a horse has Cushing’s Syndrome if it has a long, wavy haircoat and sweats a lot because of it. These horses are prone to developing laminitis, chronic infections, and loss of muscle mass, giving them a pot-bellied look. They often have increased water intake and urine output too.
Cushing’s Syndrome can’t be cured, but it can be managed. Drugs such as pergolide or Cyproheptadine (cyproheptadine hydrochloride) can help, although they are expensive and must administered throughout your horse’s life.
