Laminitis in horses involves inflammation and damage to the laminae within the hoof, often triggered by metabolic disorders, obesity, or diet issues. This painful condition can be debilitating and even fatal, making understanding its causes and prevention crucial for horse owners.
How Can Metabolic Disorders Lead to Laminitis in Horses?
Metabolic disorders, such as equine metabolic syndrome (EMS) and insulin dysregulation (ID), significantly increase the risk of laminitis in horses. These conditions disrupt the horse’s hormonal and metabolic balance, leading to a cascade of events that can compromise hoof health.
What is Equine Metabolic Syndrome (EMS)?
Equine Metabolic Syndrome (EMS) is a disorder characterized by insulin resistance, obesity (or regional adiposity), and a predisposition to laminitis. Insulin resistance means the horse’s body doesn’t respond effectively to insulin, a hormone that regulates blood sugar levels. This leads to elevated insulin levels in the blood, which can trigger laminitis.
What is Insulin Dysregulation (ID)?
Insulin dysregulation (ID) refers to abnormal insulin responses in horses, which can include both insulin resistance and exaggerated insulin release after consuming carbohydrates. ID is a key factor in the development of laminitis, as high insulin levels can disrupt blood flow to the hooves and interfere with the normal function of the laminae.
What Are the Risk Factors for Metabolic-Related Laminitis?
Several factors can increase a horse’s susceptibility to metabolic-related laminitis:
- Obesity: Overweight horses are more likely to develop insulin resistance and EMS.
- Diet: High-carbohydrate diets, especially those rich in sugars and starches, can exacerbate insulin dysregulation.
- Genetics: Some horses are genetically predisposed to EMS and insulin resistance.
- Lack of Exercise: Insufficient physical activity can contribute to insulin resistance and weight gain.
How Can You Prevent Laminitis Related to Metabolic Issues?
Managing metabolic disorders is crucial for preventing laminitis. Strategies include:
- Dietary Management: Restricting carbohydrate intake by feeding low-starch and low-sugar diets.
- Weight Management: Encouraging weight loss through exercise and controlled feeding.
- Regular Exercise: Promoting insulin sensitivity and overall health.
- Medication: In some cases, medications may be prescribed to improve insulin sensitivity.

What are the early signs of laminitis in horses?
Early signs of laminitis can be subtle but may include increased digital pulse, reluctance to turn, and a "pottery stance," where the horse shifts weight between its front feet to alleviate pressure.
How is laminitis diagnosed?
Diagnosis typically involves a physical exam, assessment of hoof pain, and blood tests to evaluate insulin levels. Radiographs (X-rays) may be used to assess the degree of lamellar damage.
Can laminitis be cured?
While there is no definitive cure for laminitis, early and aggressive management can improve the prognosis. Treatment focuses on reducing inflammation, improving blood flow to the hooves, and addressing the underlying metabolic issues.
Understanding the link between metabolic disorders and laminitis is essential for horse owners. By managing diet, weight, and exercise, you can significantly reduce your horse’s risk of developing this debilitating condition.
