New Research Sheds Light on Equine Metabolic Syndrome (EMS) in Horses
Equine Metabolic Syndrome (EMS) is a sugar metabolism disorder that affects horses, according to recent research by the Equine Endocrinology Group (EEG). The syndrome is often associated with an increased risk of hyperinsulinemia-induced laminitis, a painful hoof condition, and other related diseases.
Dr. Christian Bingold, an equine veterinarian, clarifies that EMS is often wrongly equated with diabetes, even though both diseases involve sugar metabolism disorders. However, their disease processes differ.
The main cause of EMS in horses is a combination of genetic and environmental factors. Horses can have a high genetic risk for the syndrome, making them more susceptible to developing EMS when exposed to unfavorable environmental conditions, such as overfeeding with easily digestible carbohydrates. However, even horses without a high genetic risk can develop EMS under similar circumstances, emphasizing the importance of managing environmental triggers.
One of the key aspects of EMS is insulin resistance, where the body’s response to the hormone insulin is reduced. Insulin resistance results from the disrupted interaction between sugar (glucose) and insulin, leading to insulin dysregulation.
Recognizing EMS in horses can be challenging, as the symptoms may develop gradually over years. Some common signs include fat pads around the neck, croup, and base of the tail, along with muscle shrinkage, reduced performance, increased susceptibility to infections, and fertility problems in mares. Laminitis, a condition characterized by inflammation and tenderness in the hooves, is a significant consequence of EMS.
Changes in diet, such as transitioning to spring grazing, can trigger EMS symptoms. Horses with EMS are more sensitive to fructans, natural sugars found in pasture grass. Even small amounts of fructans can lead to laminitis in EMS-affected horses, while healthy horses tolerate them without issue.
Feeding and exercise play a vital role in managing EMS. Customized feeding plans and regular exercise help reduce insulin resistance and normalize the insulin system in affected horses. Medications may also be prescribed based on individual cases.
Proper prevention is crucial in managing EMS. Understanding the disease, its causes, symptoms, diagnosis, and treatment options can help horse owners identify and manage EMS effectively. Horse owners should be aware of the risk factors associated with EMS and take necessary precautions to ensure their horses’ well-being.
