Equine metabolic syndrome (EMS) is a disorder in horses characterized by insulin resistance, obesity, and an increased risk of laminitis. It shares similarities with metabolic syndrome in humans, increasing the risk for serious health issues. Management through diet and exercise is crucial, and medication may be necessary in some cases.
What is Equine Metabolic Syndrome?
Equine metabolic syndrome is a condition primarily affecting horses and ponies, characterized by a cluster of metabolic abnormalities that elevate the risk of laminitis and other health issues. Insulin resistance is a key feature, where the horse’s tissues become less responsive to insulin, leading to elevated blood glucose levels.
What are the Risk Factors for EMS?
Several factors can contribute to the development of equine metabolic syndrome:
- Obesity: Overweight horses, particularly those with regional adiposity (fat deposits), are more prone to EMS.
- Genetics: Some breeds, such as ponies, Morgans, and Arabians, may have a genetic predisposition to insulin resistance.
- Diet: High-carbohydrate diets can exacerbate insulin resistance in susceptible horses.
- Lack of Exercise: Physical inactivity contributes to insulin resistance and weight gain.
How is Equine Metabolic Syndrome Diagnosed?
Diagnosing EMS typically involves a combination of physical examination and laboratory tests. Veterinarians assess body condition score, look for regional fat deposits, and evaluate the horse’s history. Blood tests are performed to measure insulin and glucose levels, and dynamic tests like the oral sugar test may be used to assess insulin sensitivity.
What are the Treatment Options for EMS?
Managing equine metabolic syndrome requires a multifaceted approach:
- Dietary Management: Restricting carbohydrate intake is crucial. This involves feeding a diet low in non-structural carbohydrates (NSC), such as sugars and starches.
- Exercise: Regular physical activity improves insulin sensitivity and promotes weight loss.
- Medication: In some cases, medications like metformin or levothyroxine may be prescribed to improve insulin sensitivity or manage thyroid function.
How Can I Prevent EMS in My Horse?
Prevention is key when it comes to equine metabolic syndrome. Maintaining a healthy weight through appropriate diet and exercise is essential. Avoid overfeeding high-carbohydrate feeds, and ensure your horse gets regular physical activity.

What are the signs of equine metabolic syndrome?
Common signs include obesity (especially regional fat deposits), a history of laminitis, and increased thirst and urination. Some horses may also exhibit abnormal estrous cycles or decreased fertility.
Is equine metabolic syndrome curable?
While there is no cure for EMS, it can be effectively managed through diet, exercise, and medication. With proper management, horses with EMS can live comfortable lives and maintain a good quality of life.
How does EMS relate to Cushing’s disease in horses?
While both EMS and Cushing’s disease (PPID) can cause insulin resistance and laminitis, they are distinct conditions. EMS primarily affects younger to middle-aged horses, while PPID is more common in older horses. Diagnostic testing can differentiate between the two conditions.
In summary, equine metabolic syndrome is a significant health concern in horses, but with proper management and preventative measures, its impact can be minimized.
