Cushing’s in Horses: Understanding PPID and Why Fall Testing Matters | Ep. 83

If you have an older horse, you’ve probably heard of Cushing’s disease, but how much has changed in what we know about diagnosing and managing it? In this episode, we take a closer look at pituitary pars intermedia dysfunction (PPID), the condition commonly called Cushing’s in horses, and explore why fall is an especially important time to think about testing.

We discuss:

• The early signs of PPID that are easy to mistake for normal aging
• Why the seasonal rise in ACTH makes fall an important testing window
• How ACTH testing and TRH stimulation testing differ, and how results are interpreted
• Why insulin status matters alongside a PPID diagnosis, especially when it comes to laminitis risk and nutrition
• Current approaches to treatment, monitoring, and feeding the PPID horse

If you have a senior horse, suspect PPID, or already have a horse diagnosed with Cushing’s, this episode offers an updated look at what horse owners should know about recognizing, testing, and managing this common endocrine disorder.
