Laminitis, The Consequence We Created

Laminitis is one of the most feared words in the horse world, and rightly so. It is painful, it is devastating, and in many cases it is preventable.

Before we talk about grass, feed, or management, we need to understand one simple truth.

Laminitis is not a hoof problem.

It is a systemic event that shows up in the hoof.

Inside the foot, the laminae are microscopic interlocking structures that suspend the pedal bone within the hoof capsule. They rely on stable blood flow, balanced inflammation control, and a tightly regulated metabolic environment. When that environment is disrupted, particularly through insulin dysregulation or severe inflammatory insult, those laminae weaken. The structural bond fails. Pain follows.

What we see in the hoof is the end stage of a process that began elsewhere.

The Modern Horse and the Metabolic Load

In today’s domestic environment, the most common form of laminitis is endocrinopathic. That means it is driven by metabolic disturbance, most commonly persistent high insulin levels.

Insulin is not the villain. It is a survival hormone. In a wild environment, horses would lose weight through winter, arrive at spring lean, and then regain condition gradually as nutrient density increased. Their insulin spikes were seasonal and temporary.

The domestic horse often never experiences that winter reset.

Year round calorie availability, limited movement, and high non structural carbohydrate intake create a chronic metabolic load. When spring grass arrives, rich in soluble sugars and rapidly fermentable carbohydrates, the system is already primed. The insulin response becomes exaggerated. The laminae pay the price.

This is not about blaming grass. Grass did not change. Management did.

Laminitis Is Not Random

It is uncomfortable to say this, but laminitis is rarely random.

There are three primary pathways.

First, endocrinopathic, driven by insulin dysregulation and metabolic stress. This is now the dominant form in domestic horses.

Second, inflammatory, following severe systemic illness such as colitis or retained placenta.

Third, mechanical, where excessive load on one limb compromises blood flow and laminar integrity.

The first category is by far the most common, and it is the one most closely tied to feeding and management decisions.

More Feed Does Not Mean More Strength

For decades the industry has equated visible condition with health. Roundness became a visual benchmark of “doing well.”

But adipose tissue is not inert. It is hormonally active. Excess body fat alters insulin sensitivity. It shifts inflammatory balance. It quietly moves a horse closer to the metabolic threshold where laminitis becomes possible.

Strength does not come from surplus energy. It comes from efficient energy use, healthy tissue turnover, and appropriate conditioning.

A horse that has never been allowed to cycle weight seasonally is not thriving. It is metabolically buffered, until it is not.

The Hoof Is the Messenger

When laminitis appears, it is not the beginning of the problem. It is the body signalling that systemic regulation has failed.

The answer is not simply corrective trimming or anti inflammatory medication, although those may be necessary in acute cases. The long term answer lies in restoring metabolic stability.

That means appropriate body condition, controlled exposure to high sugar pasture, movement, and feeding strategies that respect how the horse evolved to process nutrients.

It means understanding that the wild horse model was built on fluctuation, not constant abundance.

Prevention Is Management

Laminitis prevention is not complicated, but it requires discipline.

Monitor body condition honestly.

Allow safe, controlled seasonal weight loss where appropriate.

Manage spring pasture carefully, especially for horses that entered the season overweight.

Support gut integrity through consistent, appropriate feeding.

Encourage daily movement.

Do not wait for soreness to appear before making changes.

The greatest mistake we make is assuming that because a horse looks comfortable today, the system underneath is stable.

Laminitis is not an act of fate.

In many cases, it is the consequence of long term metabolic pressure that went unnoticed or unaddressed.

The good news is that when we understand the process, we can change the trajectory.

The hoof is not the enemy.

It is the final indicator that the internal balance has shifted too far.

If we listen earlier, we rarely have to listen to laminitis.
