What is Cushing's Syndrome?
Equine Cushing's Syndrome (ECS) is a hormonal disorder that commonly occurs in older horses, typically from around 15 years of age. In this age group, ECS is even one of the most widespread hormonal disorders.
ECS is often classified as a lifestyle disease because it occurs more frequently in overweight, inactive, and easy-keeper horses. In the wild, the disease is almost unknown, as the energy and sugar intake there is optimally matched to actual needs. An oversupply of nutrients, as often found in the care of domestic horses, is rare in nature.
For several years, ECS has also been referred to as PPID, which stands for Pituitary Pars Intermedia Dysfunction. This term describes the disease more precisely, as it names the part of the pituitary gland affected by ECS. Nevertheless, the term "Cushing" has become established in the equine world because it is catchier and better known.
A Cushing's diagnosis can initially be frightening for horse owners. However, with appropriate feeding, adapted management, and proper medical care, affected horses can often still lead many years of a comfortable and happy life.
Causes of ECS
The main cause of ECS lies in a malfunction of the pituitary gland. The pituitary gland, also known as the hypophysis, is a small, pea-sized organ in the brain. It is a crucial control organ in the hormonal system and influences numerous bodily functions.
As horses age, this gland can enlarge, disrupting the hormonal balance in the body. Factors such as genetic predisposition, stress, and long-term overexertion can increase the risk of the disease.
Symptoms and Effects
Equine Cushing's Syndrome (ECS) has diverse effects on the horse's body because it disrupts hormonal balance. The disease affects multiple organs and systems and manifests in various symptoms, which can vary in severity.
- Coat shedding disorders: Prolonged, curly hair growth or delayed shedding.
- Performance decline: Rapid fatigue and reduced performance capacity.
- Laminitis: Recurring laminitis episodes are one of the most common and dangerous accompanying symptoms.
- Muscle loss and fat deposits: Muscle wasting, especially along the back, as well as fat pads on the mane crest or above the eye sockets.
- Increased thirst and urination: Significantly increased drinking and urination behavior.
Treatment Options
Once your veterinarian has made the diagnosis, they will therapeutically support your horse and conduct regular check-ups. Although Cushing's is currently not curable, the disease can be well managed with targeted medication. The medications reduce the excessive hormone production in the pituitary gland and effectively prevent your horse from suffering typical symptoms such as laminitis, lethargy, or coat changes. The administration of Pergolide (Prascend) is the most common therapy. It regulates hormone production and alleviates many symptoms.
#IMPORTANT: Start treatment as soon as possible to give your horse a better quality of life.
The medications prescribed by the veterinarian usually show quick effects and relieve symptoms. Therapy often begins with a low dose to gently acclimate your horse to the medication and avoid side effects such as loss of appetite or fatigue.
If your horse still shows unwanted reactions such as colic or other side effects, it is important to consult your veterinarian. In such cases, the dosage can be adjusted or the therapy supplemented with additional preparations.
Adapted feeding, regular exercise, and good Hoof Care can also help you support your horse.
A low-carbohydrate, high-roughage diet relieves the metabolism and should consistently avoid sugary feeds. Light but regular exercise additionally supports metabolism and counteracts muscle loss.
Pay particular attention to ensuring that your horse does not (repeatedly) develop laminitis as a result of Cushing's, as this ultimately poses the greatest threat to quality of life.
Your veterinarian will be the best advisor for treating Cushing's and the consequences of the hormonal disorder.
