Laminitis, EMS & PPID 🩻🐴💉
Coming through spring and summer we’re seeing a boom in the amount of laminitis cases.
Laminitis is one of the most serious and painful conditions affecting horses and ponies, but did you know that many cases are linked to underlying hormonal conditions?
The two most common conditions are:
Equine Metabolic Syndrome (EMS) 🌾
EMS is often seen in good doers who are overweight or have regional fat deposits (such as a cresty neck). Horses with EMS produce higher levels of insulin, and persistently high insulin and glucose can trigger laminitis.
Pituitary Pars Intermedia Dysfunction (PPID) 🐎
Also known as Cushing's disease, PPID is most common in older horses and ponies. Signs can include a long or curly coat, increased drinking and urination, muscle loss, lethargy, recurrent infections, and laminitis. Horses with PPID may also develop insulin dysregulation, further increasing their laminitis risk.
How are they linked?
Both EMS and PPID can lead to insulin dysregulation, which is now recognised as one of the leading causes of laminitis. In many cases, successfully managing the underlying condition is key to reducing the risk of future laminitic episodes.
What can you do?
- Maintain a healthy body condition.
- Manage grazing carefully, especially during high-risk periods in spring and summer.
- Feed a balanced, low-sugar and low-starch diet where appropriate.
- Exercise regularly if your horse is sound and your vet advises it.
- Arrange testing for EMS or PPID if your horse is at risk or has had laminitis. This involves a simple blood test!
