    Cushing’s Disease, also known as Pituitary Pars Intermedia Dysfunction (PPID), is a common hormonal condition affecting horses, particularly older equines, and is characterized by the malfunction of the pituitary gland.

    PPID predominantly affects horses over the age of 15, with some studies suggesting that up to 30% of horses over the age of 20 may suffer from this condition.

    The pituitary gland, located at the base of the brain, plays a crucial role in regulating various bodily functions by secreting hormones. In horses with PPID, the malfunctioning pituitary gland leads to an overproduction of certain hormones, particularly adrenocorticotropic hormone (ACTH), which causes various systemic effects.

    What Causes Cushing’s Disease (PPID)?

    Cushing’s Disease (PPID) in horses is primarily caused by the dysfunction of the pituitary gland, leading to irregular hormonal regulation, particularly involving insulin and adrenal responses within the equine body.

    The pituitary gland’s malfunction disrupts the secretion of several essential hormones, such as adrenocorticotropic hormone (ACTH) and growth hormone. This irregular release of hormones leads to imbalances in the body’s metabolic and immune functions, including abnormal glucose metabolism and compromised immune response.

    The regulatory impact of these hormonal imbalances significantly impacts the equine’s physiological well-being, resulting in symptoms such as excessive hair growth, muscle wasting, increased susceptibility to infections, and laminitis.

    What Are The Symptoms Of Cushing’s Disease (PPID)?

    The symptoms of Cushing’s Disease (PPID) in horses encompass a range of manifestations, including changes in body condition, altered adrenal function, and the impact of pituitary gland irregularities on equine health.

    The changes in body condition may present as a long, curly coat that fails to shed in the summer, excessive sweating or a lack of sweating, increased thirst, and abnormal fat distribution resulting in a pot-bellied appearance.

    Altered adrenal function can lead to lethargy, muscle wastage, and increased susceptibility to infections.

    Pituitary gland irregularities may manifest as laminitis, insulin resistance, and compromised immune function.

    Excessive Hair Growth

    Excessive hair growth is a prominent symptom of Cushing’s Disease (PPID) in horses, characterized by the abnormal lengthening and thickening of the equine coat due to pituitary gland irregularities.

    This manifestation is a result of the overstimulation of the adrenal glands, leading to a surplus of cortisol in the horse’s system. As a consequence, the hormonal imbalance disrupts the natural shedding cycle, causing the coat to grow longer and thicker than usual. The excessive hair growth can be particularly noticeable in areas such as the fetlocks, mane, and tail, presenting a shaggy appearance.

    The irregularities in the pituitary gland can induce a range of systemic effects, impacting the horse’s metabolic functions, immunity, and overall well-being.

    Fatigue and Weakness

    Fatigue and weakness are common symptoms exhibited by horses with Cushing’s Disease (PPID), reflecting the impact of pituitary gland irregularities on equine energy levels and muscular function.

    The prevalence of fatigue and weakness as symptoms of Cushing’s Disease (PPID) in horses is a significant concern within the equestrian community. These symptoms often manifest due to the persistent high levels of cortisol, which originate from the malfunctioning pituitary gland. This hormonal imbalance affects the horse’s metabolism, muscle strength, and overall stamina, leading to a noticeable decline in their physical abilities. Consequently, affected horses may exhibit lethargy and muscle weakness, making it challenging for them to engage in regular exercise or maintain their usual activity levels.

    Weight Gain

    Weight gain is a notable symptom observed in horses affected by Cushing’s Disease (PPID), often stemming from irregularities in insulin levels and the impact of pituitary gland dysfunction on equine metabolic processes.

    When the pituitary gland no longer functions correctly, it can cause an overproduction of certain hormones, leading to an imbalance in insulin levels. As a result, the horse’s metabolism becomes disrupted, making it more prone to weight gain, particularly in the fatty tissue areas such as the crest of the neck and tailhead.

    The elevated cortisol levels commonly found in horses with Cushing’s Disease can lead to increased fat deposition and muscle wasting. This further exacerbates the weight gain and can also result in a compromised immune system, making the horse more vulnerable to infections and other health issues.

    Increased Thirst and Urination

    Horses with Cushing’s Disease (PPID) often exhibit increased thirst and urination, reflecting the impact of pituitary gland irregularities on equine hormonal regulation and renal responses.

    This increased thirst, known as polydipsia, is a direct result of the hormonal imbalance caused by Cushing’s Disease. The kidney’s responses to this imbalance lead to increased urination, known as polyuria. These symptoms are commonly observed in horses suffering from Cushing’s Disease (PPID) due to the abnormal secretion of hormones, particularly the increase in adrenocorticotropic hormone.

    It’s important to recognize these signs early as they can greatly affect the horse’s well-being. Owners and caretakers should keep a close eye on the water intake and urination frequency of their horses, seeking veterinary care if they observe these symptoms.


    Laminitis is a severe condition commonly associated with Cushing’s Disease (PPID) in horses, often linked to the development of insulin resistance and the impact of pituitary gland dysfunction on equine hoof health.

    The development of laminitis in horses with Cushing’s Disease (PPID) can be attributed to the insulin resistance that often accompanies this condition. Insulin resistance can lead to an abnormal glucose metabolism, setting off a cascade of events that affect the blood flow to the hooves and the integrity of the laminae. This disruption in blood flow and nutrient delivery can result in lameness and the characteristic painful hoof symptoms associated with laminitis.

    How Is Cushing’s Disease (PPID) Diagnosed?

    The diagnosis of Cushing’s Disease (PPID) in horses requires thorough evaluation by a qualified veterinarian, often involving blood tests to assess ACTH levels and the manifestation of specific symptoms.

    When a veterinarian suspects Cushing’s Disease (PPID) in a horse, the diagnostic process typically begins with a comprehensive physical examination to assess the equine’s overall health and to identify any visible symptoms such as abnormal hair coat, excessive sweating, or laminitis.

    Subsequently, the veterinarian may recommend specific blood tests to measure the horse’s ACTH levels. These tests are crucial in confirming the diagnosis as elevated ACTH levels are a key indicator of Cushing’s Disease (PPID).

    Evaluating the horse’s medical history and observing any behavioral changes can provide valuable insights and support the diagnosis. It’s important for horse owners to communicate any noticeable changes in their horses’ behavior or physical condition to the veterinarian, as this information can aid in the accurate diagnosis of Cushing’s Disease (PPID).
