A burning feeling in your chest. Pressure after meals. Discomfort that feels like reflux—but tests say your acid levels are normal.
If this sounds familiar, you’re not alone. Many people are surprised to learn that yes, you can have heartburn without classic acid reflux. And in some cases, the real issue isn’t excess acid at all—it’s a hiatal hernia, a condition that may eventually require surgical evaluation.
This blog explains why heartburn can occur without acid reflux, how hiatal hernias play a role, and when surgery becomes part of the conversation.
What Does Heartburn Really Mean?
Heartburn is a symptom, not a diagnosis. It describes a burning or uncomfortable sensation in the chest or upper abdomen, often behind the breastbone. While heartburn is commonly associated with acid reflux or GERD, acid is not always the culprit.
Heartburn-like symptoms can come from:
-
Mechanical pressure
-
Nerve sensitivity
-
Muscle dysfunction
-
Structural problems like a hiatal hernia
That’s why some people continue to feel heartburn even when acid-suppressing medications don’t help.
Heartburn Without Acid Reflux: How Is That Possible?
Yes—heartburn can occur without significant acid reflux. Here’s how:
1. Esophageal Sensitivity
Some people have a highly sensitive esophagus. Even normal amounts of stomach contents—or simple movement of the esophagus—can trigger burning or discomfort without abnormal acid levels.
2. Muscle or Pressure-Related Causes
The sensation of heartburn can come from pressure in the chest or upper abdomen, especially after eating or bending forward. This pressure can mimic reflux even when acid isn’t backing up into the throat.
3. Hiatal Hernia (A Commonly Missed Cause)
A hiatal hernia occurs when part of the stomach pushes up through the diaphragm into the chest. This changes the normal anatomy and can cause heartburn symptoms without classic acid reflux.
In these cases, the problem isn’t just acid—it’s where the stomach is positioned.
How a Hiatal Hernia Causes Heartburn Symptoms
In a healthy digestive system, the diaphragm and lower esophageal sphincter work together to keep stomach contents where they belong. A hiatal hernia disrupts this balance.
As a result, you may experience:
-
Burning in the chest after meals
-
Pressure or fullness in the upper abdomen
-
Symptoms that worsen when lying down or bending
-
Chest discomfort that doesn’t respond well to antacids
-
Regurgitation without strong acid taste
This explains why someone can ask, “Can you have heartburn without acid reflux?”—and the answer is yes, especially with a hiatal hernia.
Why Acid Reflux Medications Don’t Always Work
If heartburn is caused mainly by mechanical issues or anatomy, acid-blocking medications may offer little relief. This is often frustrating for patients who have tried multiple treatments with minimal improvement.
When heartburn persists despite medication, it’s a sign that further evaluation is needed, not just stronger pills.
When Heartburn Becomes a Surgical Conversation
For many people, lifestyle changes and medication are enough. But when heartburn is linked to a hiatal hernia, surgery may be considered—especially if symptoms are ongoing or severe.
Surgical evaluation is often recommended when:
-
Heartburn persists despite medication
-
Symptoms interfere with sleep or daily life
-
There is significant chest pressure or regurgitation
-
A large hiatal hernia is present
-
Complications such as inflammation or narrowing of the esophagus develop
In these cases, surgery focuses on correcting the anatomy, not just suppressing acid.
What Hiatal Hernia Surgery Aims to Fix
Hiatal hernia surgery is designed to:
-
Restore the stomach to its normal position
-
Strengthen the opening in the diaphragm
-
Improve the function of the esophageal sphincter
-
Reduce pressure-related heartburn symptoms
By addressing the structural cause, surgery can relieve symptoms that medications cannot.
Symptoms That Should Not Be Ignored
Seek medical evaluation if heartburn is accompanied by:
-
Chest pain that mimics heart issues
-
Difficulty swallowing
-
Persistent nausea or vomiting
-
Unexplained weight loss
-
Symptoms that worsen when lying flat
These signs suggest that heartburn may be more than simple reflux.
Final Thoughts: Heartburn Isn’t Always About Acid
So, can you have heartburn without acid reflux?
Absolutely. In many cases, the burning sensation comes from structural or mechanical issues, especially a hiatal hernia. When heartburn doesn’t respond to standard treatments, it’s a signal to look deeper—not just take more medication. Understanding the true cause of heartburn opens the door to the right treatment, whether that’s lifestyle changes, targeted therapy, or surgical correction when needed. If heartburn feels constant, unexplained, or resistant to treatment, a professional evaluation can bring clarity—and lasting relief.
