Cushing’s disease, or Cushing’s syndrome, in horses is often caused by a tumor in the pituitary gland, leading to an overproduction of ACTH (Adrenocorticotropic hormone). Diagnosing animal diseases requires recognizing clinical signs that may be obvious or subtle and confirmed through veterinary examination and lab tests. Recognizing the symptoms is crucial for early diagnosis and management.
What Are The Key Symptoms of Cushing’s Disease in Horses?
General inspection of an animal includes an examination of its appearance, behavior, body condition, respiratory movements, and the state of its skin, coat, and abdomen. Observation of these characteristics, and any deviation from the norm, is a useful aid in diagnosing disease.
Coat Changes
One of the most noticeable symptoms is hirsutism, or an abnormally long hair coat that doesn’t shed properly. Horses may also experience delayed shedding or retain a thick winter coat year-round.
Muscle Loss and Weakness
Affected horses often develop a pot-bellied appearance due to the weakening of abdominal muscles. Muscle loss, particularly along the topline, can also lead to a swayback posture.
Increased Drinking and Urination
Horses with Cushing’s disease may exhibit polydipsia (excessive drinking) and polyuria (excessive urination). This can result in frequent trips to the water source and increased stall cleaning.
Lethargy and Decreased Performance
A general decrease in energy levels and reluctance to exercise are common. Horses may seem tired or sluggish, impacting their athletic performance.
Laminitis
Cushing’s disease increases the risk of laminitis, a painful condition affecting the hooves. Recurrent laminitis episodes, especially without a clear cause, can be a sign of the disease.
Increased Susceptibility to Infections
Horses with Cushing’s are more prone to infections due to a compromised immune system. This can manifest as frequent abscesses, slow-healing wounds, or respiratory issues.

How is Cushing’s disease diagnosed in horses?
Veterinarians diagnose Cushing’s through blood tests, such as the ACTH stimulation test or the dexamethasone suppression test. These tests measure hormone levels to determine if the pituitary gland is overactive.
Can Cushing’s disease be cured in horses?
While there is no cure for Cushing’s disease, it can be effectively managed with medication. Pergolide is a commonly used drug that helps control hormone production and alleviate symptoms.
What is the prognosis for horses with Cushing’s disease?
With proper management and medication, horses with Cushing’s can live comfortably for many years. Regular veterinary check-ups and monitoring of hormone levels are essential to adjust treatment as needed.
Are there any dietary changes that can help manage Cushing’s disease in horses?
Low-sugar and low-starch diets are often recommended to help manage insulin resistance and reduce the risk of laminitis. Soaking hay to reduce sugar content and avoiding grain-based feeds can be beneficial.
How does Cushing’s disease affect a horse’s lifespan?
If left unmanaged, Cushing’s disease can significantly impact a horse’s lifespan due to complications like laminitis and infections. However, with appropriate treatment and care, many horses can maintain a good quality of life for several years.
By recognizing these symptoms and seeking timely veterinary care, horse owners can effectively manage Cushing’s disease and improve their horse’s well-being. Want to discover more about treatments for Cushing’s disease?
