Horses have been great domestic pets for centuries. Insulin resistance syndrome includes a group of problems like obesity, high blood pressure, high cholesterol, and type 2 diabetes. Insulin resistance is a disturbance of glucose metabolism that can be thought of as an early form of type 2 diabetes mellitus. Cushing's disease, a condition common in older horses, occurs when a tumor has grown in the pituitary gland in the brain and puts out large amounts of adrenocorticotropic hormone (ACTH). EMS is a problem in both horses and humans. The inflammation and weak hooves that are associated with laminitis is painful for horses. If the horse is diagnosed at an early stage, it can allow the attending veterinarian to take preventative measures rather than treatment measures in the care of the horse. EMS has some similar signs to Equine Cushings Disease, but it is a different disease with different underlying causes. Can Horses Get Diabetes: Insulin Resistance in Horses. Age – Old horses (>20 years) seem to be more prone to insulin resistance. This condition can quickly lead to laminitis, if left untreated, and… Read More »Insulin Resistance In IR/Insulin Resistance in horses, the cells are unable to properly utilize the insulin. For those of you new to Equine Challenge Supplements, we have a specific protocol for IR horses or for horses that are overweight (easy keepers). With proper care, these horses … The most obvious symptoms of Insulin Resistance in horses are hardened and thickened manes, often combined with wrinkles. Care and attention is a vital part while nurturing a pet animal. Horses with EMS become less sensitive to insulin’s effects, and more insulin than normally required is needed to keep blood sugar concentrations within normal limits, especially after … A potential link between insulin resistance and iron overload disorder in browsing rhinoceroses investigated through the use of an equine model. In order to ensure the longevity and performance of your horse, understanding the similarities and differences between both of these disorders can help with choosing the best treatment options so that your horse can feel more comfortable and happy. For many people, insulin resistance often doesn’t trigger any noticeable symptoms, especially in the early phases. Research is showing that Cushings may be occurring earlier and earlier in horses due to high Insulin damaging Pituitary cells. Cushings is very common in middle-aged to older horses (18-23 years), and it causes great discomfort for them. Why we are seeing IR in horses in epidemic numbers. Equine insulin Resistance can cause several symptoms such as unusual fat deposits, excessive drinking and urinating, loss of muscle mass and laminitis. Horse owners in recent years have been introduced and marketed to more and more commercial foods which typically contain a great deal of byproduct waste. Chasteberry … New studies, from the Universities of Kentucky and Virginia, suggest that half of the horse population is overweight and insulin resistance is a probable, normal event in geriatric horses. It … This article elaborates on effects and treatment of insulin resistance for equine pets. The best treatment for Cushings in horses involves an approach that includes managing the symptoms and hormonal imbalances associated with it. Equine insulin resistance is now the #1 cause of laminitis in the world. Insulin resistance is likely an early warning of additional metabolic related diseases, including colic and laminitis, and endocrine related problems such as Cushings. This syndrome is currently defined by the presence of 1) insulin resistance (IR), 2) obesity and/or regional adiposity, and 3) prior or current laminitis. Insulin resistance in fat cells reduces the effect of insulin and lead to increased triglyceride hydrolysis reserves, if no steps are good for increasing insulin sensitivity or by providing extra insulin. Diabetic symptoms would almost always come before a horse … Insulin resistance (IR) is defined as reduced sensitivity to insulin that results in increased insulin release and/or decreased activity of insulin, such as glucose entry into cells, inhibition of glucose production in the liver, and mobilization of fat. Journal of Zoo and Wildlife Medicine, 43 (3), S61-S65. Insulin resistance therefore promotes weight gain.Obesity leads to insulin resistance We also know that obesity can cause insulin resistance. Horses will often rub their manes as a result of the irritation. Chasteberry has been shown to improve glucose tolerance and insulin sensitivity in some horses with insulin resistance, a common contributing factor to laminitis. Horses most commonly have compensated insulin resistance and rarely develop pancreatic exhaustion and type 2 diabetes (Durham and others 2009). [xi] Getty, J.M. Insulin resistance occurs when excess sugar circulates in the body. Insulin resistance alone can be identified through a simple blood test performed after at least six hours of fasting. The cells then become less sensitive to the actions of insulin and absorb less energy. Diabetes in horses is also called “insulin resistance.” For a long time, it was thought that horses couldn’t contract “diabetes,” and that they could only develop Cushing’s disease. “If the insulin concentration is above 20 micro-units per milliliter [after fasting] the horse is said to be insulin resistant,” says Pratt-Phillips. Recognizing Early Signs. Altered glucose and insulin levels may also lead to altered epidermal cell function and glucose uptake by epidermal laminar cells. The primary characteristic of EMS is insulin resistance, now more commonly referred to as insulin dysregulation. Insulin Resistance (IR) is a commonly used and poorly understood term. Uncompensated insulin resistance refers to pancreatic exhaustion, whereby the pancreas is no longer able to produce enough insulin and glucose control is poor; that is, type 2 diabetes. Insulin resistance plays a significant role in aberrant carbohydrate metabolism, which manifests itself in a variety of disorders including Equine Metabolic Syndrome (EMS), Laminitis, and Equine Cushing’s Disease (PPID). IR – Insulin Resistance: What is it really? Printed in: Natural Horse Volume 8, Issue 5 . Insulin has vasoregulatory actions. In addition, mosquitoes tend to be drawn to horses with Insulin Resistance, possibly due to the fact that their blood tastes sweeter and their immune systems are weaker. Insulin Resistance/Equine Metabolic Syndrome (EMS) in Equines. The horse Insulin hormone is the key hormone to get tested, but if you are concerned enough to test, also check the Glucose, total T4 and the ACTH (if suspect Cushings). You could be insulin resistant for years without knowing, especially if your blood glucose levels aren’t checked. Insulin resistance (IR) can arise from a disease (PPID / Cushing), but it is also very often caused by a horse being given too much or too energy-rich nutrition for a long time. At this point we have too little information to confirm that the disease occurs in lean horses, but research might find otherwise in the future. Horses in their late teens and those more than twenty years old can exhibit many of the "classic" signs of what has been called Cushing's disease, including obesity, long hair, increased urination and drinking, muscle wasting and difficult-to-treat laminitis. Although the increase in levels of these two hormones is due to inflammatory changes on a cellular level, the rise in levels can contribute to various health problems in the horse. Insulin resistance Insulin resistance (IR) is becoming increasingly common in our equestrian population but is often overlooked by owners. Symptoms of Insulin Resistance. Insulin resistance has profound consequences for affected horses, yet there are currently no licensed treatment options. Laminitis is a disease that affects the hooves of the horse, causing inflammation and lameness. Too much iron can be detrimental to the insulin resistant horse. Insulin resistance can decrease nitric oxide production and promote vasoconstriction. If you suspect Cushings, always test the Insulin at the same time. Yes, they do share a lot of symptoms but the main difference is that EMS affects a horse’s ability to produce insulin (which is why it sometimes referred to as an insulin-resistant condition) whereas Equine Cushing’s Disease only affects the pituitary gland. If a horse takes in more energy over a longer period of time than it uses for daily life and work, all kinds of problems arise. The symptoms seen in horses with Metabolic syndrome range from mild to severe and can begin as early as seven years of age. For more info on this, visit the Equine Insulin Resistance & Equine Hypothyroidism page. Breed – Ponies tend to have higher degrees of insulin resistance than Warmbloods or Standardbreds. Insulin regulates sugar (glucose) in the horses blood; for some reason, horses that have insulin resistance become less sensitive to insulins effects. Mostly, horse people associate it with “hard, cresty necks,” fat deposits on the rump and shoulders, excess weight, Cushing’s syndrome, and the threat of a laminitic episode. Resting insulin values also tend to be higher in ponies compared to horses but we need more data before it will be possible to derive different cutoffs for diagnosis of insulin resistance. In addition to observing the symptoms listed above, early insulin resistance can be diagnosed with specialized blood tests. Tubing the horse with glucose to measure the insulin response or giving intravenous infusions of glucose and insulin are two possible procedures but do carry some risk of inducing laminitis in a sensitive horse. If after reading this you recognise any of the symptoms in your own horse, we highly recommend you speak to your vet as a priority. In some people, the cells do not respond to insulin properly, and this condition known as insulin resistance symptoms. This means that more insulin than would normally be required is needed to keep blood sugar concentrations within normal amounts, especially after a meal high in starch and/or sugar. Though considered a robust and a strong pet, it is still prone to many diseases. Insulin and leptin resistance are very common in the horse suffering from equine metabolic syndrome. The horse’s pancreas, an important organ of the endocrine system, produces and regulates the release of insulin, a hormone that functions to metabolize and balance the body’s main source of fuel, glucose.
