🌿 When the Liver Whispers: Understanding Raised Liver Enzymes in Horses

A healthy liver is at the heart of your horse’s wellbeing — supporting energy, balance, and natural detoxification every day.

It often starts with a routine blood test. Your vet calls with the results — “Liver enzymes are a little high.”

Not catastrophic. Not an emergency. But enough to make your stomach drop.

If you’ve ever been in that position, you’re not alone. Subtle liver changes are surprisingly common, especially in horses with metabolic issues such as Equine Metabolic Syndrome (EMS) or PPID (Cushing’s disease). The good news? With the right knowledge and management, you can make a real difference.

At Dr Silver, we believe the liver deserves just as much attention as the gut, hooves, and joints — because it quietly supports everything your horse does.

💚 Why the Liver Matters

The horse’s liver plays a vital role in detoxification, nutrient balance, and metabolic health — quietly supporting every system in the body.

Think of the liver as your horse’s internal “filter and fuel plant.” It processes nutrients, removes toxins, regulates energy, and supports hormone balance.

When that system starts to struggle, enzymes such as GGT, AST, or GLDH rise in the bloodstream — a gentle whisper from the liver that it’s working harder than usual.

🔍 Common Reasons for Elevated Liver Enzymes

Every horse is different, but here are the main reasons your vet might spot raised liver markers:

1.

Metabolic Stress (EMS or PPID)

Ponies with metabolic conditions often carry extra fat or experience insulin resistance. These changes make the liver work overtime — processing fat, sugar, and hormones. The result is often mild but persistent enzyme elevation.

2.

Feed- or Environment-Related Toxins

Contaminated or mouldy hay, weeds such as ragwort, and naturally occurring mycotoxins can all challenge the liver. Even small, repeated exposures matter. Choosing clean, well-stored forage and avoiding unknown plant material goes a long way.

3.

Medications

Some veterinary drugs can temporarily raise liver values. Always follow your vet’s advice and schedule follow-up tests if your horse needs long-term treatment.

4.

Fat Build-Up (Hepatic Lipidosis)

Overweight ponies, or those that stop eating during illness, may develop fat deposits in the liver — especially if they already have EMS. This can be serious but is usually preventable with careful diet management.

5.

Stress, Infection, or Inflammation

Illness, systemic infection, or even prolonged stress can push liver values upward. Supporting the immune system and reducing unnecessary stress helps keep the liver in balance.

🌾 Practical Ways to Support Liver Health Naturally

The most effective changes are often the simplest:

• Feed clean, dust-free forage and check for mould or weeds.

• Use food-safe containers for hay soaking and feed preparation.

• Control weight and manage metabolic conditions with a low-sugar, high-fibre diet.

• Encourage regular movement suited to your horse’s ability.

• Book periodic blood checks to monitor progress.

These small habits create the foundation for a healthier liver and a happier horse.

🌟 Key Takeaway

Raised liver enzymes don’t always mean disease — they mean awareness. They’re a signal to pause, look closer, and fine-tune management before bigger issues appear.

With attentive care, clean nutrition, and regular monitoring, most horses can maintain strong, healthy liver function for years to come.

💚 The liver may whisper, but if we listen early — our horses can shine brighter for longer.
