Equine Metabolic Syndrome: A Comprehensive Guide
Equine Metabolic Syndrome (EMS) is a complex condition affecting horses and ponies, characterized by insulin dysregulation and an increased risk of laminitis. Insulin dysregulation in EMS leads to abnormal responses to dietary carbohydrates, causing increased insulin secretion and elevated blood glucose levels. This imbalance can result in clinical signs such as obesity, regional fat deposition, infertility, and laminitis.
EMS is often seen in Native breeds such as Welsh, Dartmoor and Shetland ponies, as well as in certain horse breeds like Arabian and Warmbloods. However, it can affect horses of any breed or age.
Key Highlights

EMS involves insulin dysregulation and a high risk of laminitis, especially in ponies and overweight horses.

Risk factors include obesity, breed predisposition, and high-NSC diets (e.g., sugary/starchy feeds).

Signs include a cresty neck, fat pads, and recurrent laminitis.

Management focuses on diet, weight loss, exercise, and vet care to reduce risks and support long-term wellbeing.

Understanding EMS
EMS is an endocrine disorder where horses struggle to regulate the release of insulin. In normal horses, insulin prompts tissue to absorb glucose after a meal. With EMS, fat deposits release hormones that interfere with tissue response to insulin, causing “insulin resistance”. The pancreas increases insulin release to counteract this, resulting in elevated insulin levels after meals and sometimes throughout the day. This mirrors metabolic issues in human type 2 diabetes.
Causes and Risk Factors of Equine Metabolic Syndrome (EMS)
Equine metabolic syndrome (EMS) has various causes and risk factors, including both genetic predisposition and environmental influences. While the exact underlying mechanisms are not fully understood, research suggests that EMS is a multifactorial condition with complex interactions between genetics, diet, and other factors.
Genetic Predisposition
Genetics play a significant role in the development of equine metabolic syndrome (EMS). Certain breeds, such as ponies, donkeys and Arabians, are more susceptible to EMS due to their genetic makeup. These breeds have evolved in harsh environments where resources were limited, leading to a higher efficiency in metabolizing dietary carbohydrates and storing energy.
Within these breeds, there may be individual horses with specific genetic factors that contribute to their inability to respond properly to dietary carbohydrates. These hereditary factors can result in insulin dysregulation and increased risk of developing EMS.
While genetic predisposition is a significant factor, it is essential to note that environmental influences and lifestyle factors also contribute to the development and progression of EMS. Therefore, a holistic approach that considers both genetic and environmental factors is necessary for managing EMS in horses.
Obesity
Obesity in horses can lead to Equine Metabolic Syndrome (EMS) primarily due to its role in promoting insulin resistance. Excess adipose tissue releases inflammatory substances and hormones, which interfere with insulin signalling pathways. This insulin resistance causes cells to become less responsive to insulin, leading to elevated insulin levels as the pancreas compensates. Chronic high insulin levels are a key feature of EMS and contribute to metabolic disturbances such as increased fat deposition.
Dietary Factors
Diets high in easily digestible carbohydrates, such as cereals and rich grass, can overwhelm the horse’s digestive system and lead to spikes in blood glucose levels. This frequent exposure to high-carbohydrate meals can result in insulin resistance over time, as the cells become less responsive to insulin’s signals to take up glucose. Consequently, the pancreas compensates by producing more insulin to regulate blood sugar levels, which can eventually lead to elevated insulin concentrations – a clinical sign of EMS.
Lack of Exercise
The lack of exercise contributes to EMS by reducing insulin sensitivity in horses. Regular physical activity is essential for maintaining insulin sensitivity by promoting glucose uptake into muscles, which helps regulate blood glucose levels effectively. Without adequate exercise, muscles become less responsive to insulin, leading to insulin resistance. This resistance prompts the pancreas to produce more insulin to compensate, eventually resulting in elevated insulin levels—a key characteristic of EMS. Additionally, sedentary horses are more prone to obesity as unused energy from feed is stored as fat, exacerbating insulin resistance and further increasing the risk of EMS.

Recognising clinical signs of EMS
Recognising the clinical signs of EMS is crucial for early diagnosis and effective management. Here are some important symptoms to watch out for:
Management and Prevention Strategies
Exercise Strategies
Exercise plays a crucial role in managing EMS primarily by improving insulin sensitivity and promoting weight loss. Strategies include daily turnout in with controlled grazing, which encourages natural movement and reduces obesity risk. Incorporating regular sessions of walking, trotting, and occasional cantering helps improve cardiovascular fitness and muscle tone without undue stress on joints. Additional activities such as lunging, groundwork, hacking on varied terrain, and in-hand work with obstacles provide mental stimulation, enhance coordination, and promote muscle development. For horses needing low-impact options, swimming offers a beneficial alternative. It’s crucial to monitor each horse’s response, gradually increase exercise intensity to prevent injury.
While medications that improve insulin sensitivity are used in human metabolic syndrome, their efficacy in horses, such as metformin, remains uncertain due to absorption concerns. Various supplements like chromium, magnesium, cinnamon, and chasteberry extract have been suggested for EMS in horses, but current evidence does not support their efficacy, and their use cannot be recommended.

Diagnosis of EMS
Diagnosing EMS typically begins with an assessment based on the appearance of obesity and a history of laminitis. To confirm EMS and assess insulin resistance accurately, testing should be conducted after the horse has fasted and is not in pain or stressed (e.g., during a laminitis episode). Diagnostic methods include:


Dietary Strategies for a Horse with EMS
The key principles for preventing and treating Equine Metabolic Syndrome (EMS) are straightforward: implement dietary restriction and encourage regular exercise. These measures not only promote weight loss but also enhance overall fitness, improving insulin responsiveness.
Dietary Adjustments:
Did you know all of Pure Feed’s low calorie range is suitable for horses with EMS?
Limiting field access, especially during periods of lush growth such as Spring, helps control carbohydrate intake and prevent insulin spikes.
Did you know all of Pure Feeds complete feeds already contain a balancer! So already contain all of the essential nutrients required!
Omega-3 fatty acid supplementation, sourced from fish oil or linseed oil, may further reduce inflammation, improve insulin sensitivity, and enhance cardiovascular function in horses with EMS.
Pure Linseed is a great source of Omega 3 – and a little goes a long way! Check it out here
Managing insulin spikes with strategies like feeding frequent small meals helps promotes stable blood glucose levels, contributing to effective EMS management.
Consider weight loss strategies such as using a grazing muzzle, soaking hay and triple netting to help control obesity.
Conclusion
In conclusion, managing EMS requires a well-rounded approach. Early recognition of clinical symptoms, like obesity and recurrent laminitis is key for timely treatment. Effective management includes providing a low-NSC (non-structural carbohydrate) diet, limiting field access, ensuring a balanced intake of essential nutrients, and supplementing with omega-3 fatty acids. Regular, appropriate exercise enhances insulin sensitivity and aids in weight loss. Consistent monitoring and veterinary guidance are essential to prevent complications like laminitis and to improve the horse’s overall health.

We love hearing how Pure Feed is making a difference! Here’s Jemma’s experience with Yogi:
"Honestly, my horses were on another feed for nearly 10 years before I switched them to Pure about a year ago and the difference has been huge. They absolutely love the feed, their coats and condition look incredible, and they just seem so much happier.
Yogi can be really sharp in the winter, but since being on Pure, I haven’t needed to give him a calmer at all! I rave about you guys to anyone who’ll listen!"

Did you know the entire Pure Feed range is completely molasses free?
We never rely on sweeteners to make our feeds tasty. Horses naturally prefer fibre-rich ingredients, and our formulations are designed to work with their digestive system, not against it with added sugar.
Many feeds use molasses as a shortcut: it’s cheap, it binds pellets easily, and it guarantees sweetness. But it also increases sugar levels and can make feeds unsuitable for horses with metabolic or digestive sensitivities.
At Pure Feed, we take a different approach.
Our pellets are bound using linseed and we use carefully balanced fibre and oil sources, not molasses. This means:
• Lower sugar and starch levels across the entire range
• Consistent, gut-friendly nutrition
• No artificial sweetness masking poor-quality ingredients
• Suitable for good doers, laminitics, and horses with EMS or digestive sensitivities
Delicious, nutritious, and naturally palatable - that’s the Pure Feed way 🩵
