Ulcers, Stress, and the Nervous System: Why Gut Health Isn’t Just About Supplements

If Your Horse Has Ulcers, You’re Not Alone

Ulcers are one of the most common issues seen in horses today. Over 70% of horses with a job will get them.

And if you’ve gone down this path, you’ve probably already tried:

  • gut supplements

  • ulcer support products

  • feeding changes

  • medications like omeprazole

Sometimes they help. Sometimes they don’t.

Or they work… and then the problem comes right back (especially with ulcer medicine)

That’s where this conversation needs to shift.

Because ulcers are not just a stomach problem.

They’re often a nervous system problem first.

The Science: How Stress Directly Impacts the Horse’s Gut

Horses are prey animals.

Their bodies are designed to constantly scan for changes in their environment.

That system is controlled by the autonomic nervous system, which has two main branches:

  • Sympathetic (fight or flight)

  • Parasympathetic (rest, digest, repair)

When a horse spends too much time in a sympathetic state, several things happen:

1. Reduced Blood Flow to the Gut

Blood is redirected to muscles for survival.

This means:

  • less oxygen to the stomach lining

  • reduced ability to repair tissue

  • increased vulnerability to acid damage

2. Decreased Digestive Function

The parasympathetic system is responsible for digestion.

When it’s not active:

  • gastric emptying changes

  • enzyme production is altered

  • the gut becomes less efficient

3. Increased Cortisol

Chronic stress elevates cortisol. (Just like with humans)

Research has shown that elevated cortisol:

  • impacts immune function

  • alters gut barrier integrity

  • contributes to inflammation (which can ALSO cause other issues like allergies)

4. Behavioral + Physical Feedback Loop

This is where it gets missed.

A horse with ulcers:

  • becomes more reactive

  • braces more

  • struggles under saddle

That increases stress… which worsens the gut.

It becomes a loop. Its a horrible terrible loop most horse owners DREAD (me included).

What Research and Observation Both Show

Studies on equine gastric ulcer syndrome (EGUS) consistently link ulcers to:

  • confinement and limited turnout

  • high-concentrate, low-forage diets

  • intense training schedules

  • transportation and competition stress

But here’s the key point:

Even when those factors are improved…
some horses still don’t fully resolve

Why?

Because the nervous system has learned to stay on.

Why Supplements Alone Often Fall Short

Supplements can:

  • buffer acid

  • support the gut lining

  • improve microbiome balance

All important.

But they do not directly change:

  • the horse’s perception of safety

  • their baseline stress level

  • their nervous system state

So you can be doing “everything right”…

…and still not getting full results.

Where Regulation Comes In

For healing to happen, the body has to shift into a state where it can heal.

That means activating the parasympathetic nervous system.

In horses, this looks like:

  • licking and chewing

  • blinking and softening through the eye

  • lowering the head and neck

  • relaxed breathing

  • releasing through the body

This is not just “relaxation.” This is a biological state change that allows:

  • improved digestion

  • tissue repair

  • reduced inflammation

Now Let’s Talk About Energy (Without Leaving the Science Behind)

This is where some people tune out… but it’s worth understanding.

The body is not just chemical.

It is also electrical.

  • The heart produces an electromagnetic field

  • The nervous system runs on electrical signals

  • Cells communicate through electrical gradients

This isn’t just a theory.

So when we talk about “energy,” we’re not stepping outside science…We’re just talking about the body in a different language.

How This Connects to the Solar Plexus and Root Chakra

If you’re familiar with chakras, you’ll recognize these two immediately.

Root Chakra (Safety and Survival)

This relates to:

  • security

  • grounding

  • basic survival

In the physical body, this aligns closely with:

  • the nervous system’s threat detection

  • muscle tension patterns

  • the horse’s baseline sense of safety

A horse that does not feel safe will:

  • stay in sympathetic activation

  • struggle to relax

  • have difficulty regulating digestion

The root must be balanced for all the other chakras to follow it. Its the ‘root’ of you energetic tree.

Solar Plexus Chakra (Gut, Power, Processing)

This is where things get very interesting.

The solar plexus is directly associated with:

  • digestion

  • metabolism

  • personal power and processing

The solar plexus is also a real structure:
a network of nerves located behind the stomach.

This is part of the enteric nervous system, often referred to as the “second brain.”

This system:

  • communicates constantly with the brain

  • regulates digestion

  • responds to stress signals

So when people talk about “gut feelings” or “processing emotions”…

there is a real physiological basis for it.

Putting It All Together

When a horse is stuck in stress:

  • Root (safety) is compromised

  • Solar plexus (digestion) is affected

You see it as:

  • ulcers

  • tension

  • reactivity

  • inconsistency

You treat the gut…

…but if you don’t address the underlying state of the nervous system, the cycle continues.

Where This Is Going: A More Complete Approach

The most effective approach is not choosing one path.

It’s layering:

  • proper feeding and forage

  • thoughtful supplementation

  • turnout and movement

  • correct tack and comfort

  • bodywork

  • and nervous system regulation

This is where modalities like Reiki come in.

This is what I feel like is such a large missing piece of horse wellness. Regulation! Now there are a million and one ways to do it and it doesnt HAVE to be with Reiki, but Reiki not only helps to regulate, but to HEAL, which is why its one of my favorites.

TLDR; version

If your horse is dealing with ulcers, gut issues, or chronic tension…

Don’t just ask:

“What should I give them?”

Start asking:

“What state is their body in every day?”

Because healing doesn’t just depend on what goes into the horse.

It depends on whether their system is able to receive it.

Where Can My Horse Get Reiki?

If you’re working through ulcers, stress, or chronic tension with your horse and feel like something is missing…

I offer both in-person and virtual sessions that focus on:

  • nervous system regulation

  • bodywork

  • and energy-based support

Or explore distance sessions if you’re not local.

Locally I travel to Georgia, South Carolina, and North Carolina for Reiki, Bodywork, and Bit Fitting.

Healing the gut means supporting the whole horse

Supplements matter. Nutrition matters. Management matters. But so does the nervous system. When safety improves, digestion can too.

A horse that feels safer in the body can often digest, process, and heal more effectively.
