Is It a Hiatal Hernia?
Hernias are something that physicians look for when we do annual physicals, and certainly when a person complains of intense abdominal pain.
The typical hernia you might think of is when an internal organ protrudes into a space in the body that it shouldn’t go in.
Usually, this is part of the intestines or fatty tissue that pushes through a weak spot in the surrounding muscle or connective tissue (ouch).
Think of it like a tire with a worn area in the sidewall: under pressure, the inner tube starts to bulge outward where the structure is weakest.
The most common types are:
-
Inguinal hernias (in the groin) — by far the most common, especially in men
-
Umbilical hernias (near the belly button)
-
Ventral or incisional hernias (through a previous surgical site or weakened abdominal wall)
A hiatal hernia is different, less severe, and more common than many people might imagine.
Why It’s Not Necessarily Indigestion
Sometimes, when patients come in describing chronic indigestion, reflux, chest pressure, or a vague sense that something just isn’t sitting right, they might think they have a gut imbalance.
Which is never a wrong assumption, given the prevalence of gut issues among Americans.
The problem for these people is that, though they have tried antacids, acid blockers, and even integrative techniques, they’re not getting any relief.
Some have been told it’s simply “GERD” or stress.
But when we take a step back and look more closely, a surprisingly common contributor begins to emerge: the hiatal hernia.
A hiatal hernia occurs when part of the stomach pushes upward through the diaphragm (that’s the muscular barrier that separates the chest from the abdomen) through an opening called the esophageal hiatus.
They don’t usually come from a single moment or event. In most cases, they develop gradually. When pressure inside the abdomen consistently meets a diaphragmatic vulnerability.
That opening is meant to allow the esophagus to pass through and connect to the stomach. But when the upper portion of the stomach slips through that space, it can disrupt the normal pressure dynamics between the chest and abdomen.
The diaphragm and lower esophageal sphincter (LES) normally work together like a coordinated valve system, helping keep stomach contents where they belong. You don’t want things meant to go down, coming up.
When a hiatal hernia is present, that coordination can weaken.
This is where symptoms that are generally associated with other conditions might crop up.
Symptoms like:
-
Bloating
-
Early satiety
-
Difficulty swallowing
-
Chest discomfort
-
Chronic throat clearing
-
A sensation of not having digested food fully.
-
And breathing restrictions in some individuals.
So when other treatments don’t resolve these issues, it’s not a bad idea to consider a hiatal hernia as a possible cause.
What’s important—and often missed—is that not all hiatal hernias behave the same way.
Some are small and largely asymptomatic. Others create ongoing mechanical and functional stress that can perpetuate symptoms even when acid levels are reduced.
This is where a more integrative lens becomes useful.
How Integrative Techniques Can Help With Hiatal Hernias
Conventional care for hiatal hernias often focuses on suppressing stomach acid, which I’ve argued before is rarely the best treatment for reflux, much less a hiatal hernia.
Minimizing stomach acid doesn’t usually fully address the underlying mechanics or contributing factors that led to the hernia becoming symptomatic in the first place.
From an integrative standpoint, I think about hiatal hernias less as an isolated structural issue and more as part of a broader system involving pressure, tissue integrity, digestion, and nervous system tone.
There are several areas where research, while still evolving, suggests we can support the body in meaningful ways.
One of the more underappreciated aspects of hiatal hernias is their mechanical nature.
What I mean by that is the position of the stomach relative to the diaphragm can sometimes be influenced by posture, breathing patterns, and fascial tension.
Manual therapies can help move the stomach into a position that relieves the pressure that forces it up.
Therapies like osteopathic manipulative treatment (OMT), visceral manipulation, and targeted physical therapy have been explored as ways to improve diaphragmatic function and reduce symptoms.
Some small clinical studies and case series suggest that osteopathic techniques may help improve symptoms of gastroesophageal reflux and functional digestive complaints, possibly by restoring mobility and coordination between the diaphragm and stomach.
See, the diaphragm is not just a breathing muscle, as people often think.
It’s also a structural support for the upper digestive tract.
Shallow, chest-dominant breathing can reduce diaphragmatic tone and contribute to pressure imbalances across the hiatus. Over time, this may exacerbate symptoms or make them more persistent.
Emerging research suggests that diaphragmatic breathing exercises may improve reflux symptoms by strengthening the anti-reflux barrier.
If you have a hiatal hernia and plan to use this kind of therapy to relieve it, simply think of it as “retraining the diaphragm to do its full job again.” It’s a simple intervention, but when done consistently, it can shift the distribution of pressure in the upper abdomen.
Other Lifestyle Factors That Trigger Hiatal Hernias
1 – Weight and Heavy Straining:
We can’t talk about hiatal hernias without talking about pressure…specifically, intra-abdominal pressure.
Factors such as being overweight, chronic straining (from constipation or heavy lifting), and even prolonged sitting can increase pressure on the diaphragm.
Over time, this can contribute to hernia formation or symptom progression.
Now this probably doesn’t come as a surprise, but one of the biggest factors is that higher body weight is often associated with an increased risk of hiatal hernia and reflux symptoms.
Going back to my many articles on weight loss, committing to gradual, sustainable changes that reduce your body weight can help immensely.
If, on the other hand, heavy lifting is causing the issue, then training, bracing, or bracing devices may also help.
2 – Meals and How You Eat Are Another Significant Factor:
Patients are often told to avoid “trigger foods,” and while that can be helpful, it’s only part of the picture.
From a functional perspective, I’m often more interested in how well someone is digesting their food.
Poor digestion…whether from low stomach acid, rapid eating, or chronic stress…can lead to increased gas and bloating, which in turn raises intra-abdominal pressure.
There is some evidence suggesting that meal size, timing, and composition can influence reflux symptoms. Smaller, more evenly spaced meals and avoiding late-night eating are commonly supported strategies.
Thankfully, there can be quick and effective improvements simply by slowing how fast you eat… chewing your food more thoroughly… and creating a more relaxed environment around meals.
These aren’t dramatic changes, but they work and are sustainable, which is great.
3 – And your Nervous System:
One area that’s often overlooked in relation to the digestive system and hernias is that the digestive system is highly responsive to the autonomic nervous system.
Chronic stress can alter motility, increase visceral sensitivity, and even affect diaphragmatic function.
In practice, I see that when we support the nervous system, whether that’s through sleep, breathing, and stress regulation, digestive symptoms often become more manageable.
Not because the hernia disappears, but because the system becomes more resilient.
Do This if Your Digestive Issues Don’t Resolve
If you’ve been dealing with digestive issues and the list of symptoms above sounds similar to what you’re dealing with, do this.
First, acknowledge it could be a hernia
Hiatal hernias are common. In many cases, they’re manageable.
And in some cases, they’re a missing piece of the puzzle for people dealing with persistent digestive symptoms without clear answers.
Most hiatal hernias are not dangerous, but they can contribute to ongoing symptoms if not addressed.
The main concerns are chronic acid reflux, esophageal irritation, and, over time, potential changes to the esophageal lining.
In less common cases, such as larger paraesophageal hernias, the stomach may become trapped, which can cause more severe pain, nausea, or difficulty swallowing and requires prompt evaluation.
Diagnosis typically involves imaging and visualization rather than a physical exam. The most common tools are:
-
Upper endoscopy (EGD) to directly view the esophagus and stomach
-
Barium swallow to assess how the esophagus and stomach move during swallowing
In some cases, additional testing, such as manometry, may be used. In practice, diagnosis is guided by symptoms, severity, and the extent to which the hernia affects daily function.
Treating Hiatal Hernia
What I’ve learned over time is that the most effective approach is rarely about one single intervention.
It’s about understanding the interplay between structure, pressure, digestion, and nervous system tone, and working with the body to restore balance where possible.
That might include conventional treatments when needed. It might include manual therapy, breathing work, nutrition changes, or lifestyle adjustments. Often, it’s a combination.
The goal isn’t perfection. It’s progress… reducing symptoms, improving function, and helping patients feel more at ease in their bodies over time.
And that’s where an integrative approach can be particularly valuable: not by replacing standard care, but by filling in the gaps that are often left unaddressed.
