If you have ever experienced that burning sensation in your chest after eating, you know how uncomfortable and concerning it can be. But did you know that not all reflux is created equal?

Millions of Canadians suffer from some form of reflux, yet many do not realize there are distinct types, each with different symptoms, causes, and treatment approaches. Understanding whether you have acid reflux, GERD, or LPR (silent reflux) is crucial for finding the right treatment and preventing long-term complications.

In this article, our naturopathic doctors explain the key differences and share evidence-based natural approaches to address the root cause of your reflux.

What Is Reflux?

Reflux occurs when stomach contents flow backward into the esophagus. While a small amount of reflux is normal, when it becomes frequent or severe, it can cause symptoms and damage to the esophageal lining.

The key difference between types of reflux lies in what is being refluxed and where it travels:

  • Acid reflux – Stomach acid flowing into the lower esophagus
  • GERD – Chronic, severe acid reflux with complications
  • LPR (Silent Reflux) – Stomach contents reaching the throat, voice box, and respiratory tract

The Three Types of Reflux Explained

1

Acid Reflux (Heartburn)

Also known as Gastroesophageal Reflux (GER)

Acid reflux is the most common form, characterized by stomach acid flowing back into the esophagus. It typically occurs after meals and causes a burning sensation in the chest (heartburn).

Common Symptoms:

  • Burning sensation in the chest (heartburn)
  • Sour or bitter taste in the mouth
  • Regurgitation of food or sour liquid
  • Discomfort after eating large or fatty meals

Common Triggers:

Spicy foods Citrus fruits Tomatoes Chocolate Caffeine Alcohol Large meals
2

GERD (Gastroesophageal Reflux Disease)

A chronic, more severe form of acid reflux

GERD is diagnosed when acid reflux occurs more than twice per week or when symptoms are severe enough to impact quality of life. Unlike occasional heartburn, GERD can lead to inflammation and damage to the esophageal lining.

Common Symptoms:

  • Frequent heartburn (2+ times per week)
  • Difficulty swallowing (dysphagia)
  • Chronic cough
  • Laryngitis or hoarse voice
  • Chest pain that mimics heart attack
  • Sleep disruption due to symptoms

Potential Complications:

  • Esophagitis – Inflammation of the esophagus
  • Esophageal strictures – Narrowing of the esophagus
  • Barrett's esophagus – Precancerous changes to esophageal lining
  • Respiratory complications – Asthma, pneumonia risk

LPR (Laryngopharyngeal Reflux) – Silent Reflux

The "silent" condition that affects the throat and airways

LPR occurs when stomach acid travels all the way up to the throat, voice box (larynx), and even the nasal passages. Because symptoms often do not include classic heartburn, it is called "silent reflux" and frequently goes undiagnosed.

Common Symptoms:

  • Chronic throat clearing or cough
  • Sensation of a lump in the throat (globus)
  • Hoarse voice, especially in the morning
  • Post-nasal drip
  • Difficulty swallowing
  • Chronic sore throat
  • Ear fullness or popping
  • Asthma-like symptoms

Why "Silent"?
Many people with LPR never experience heartburn because the acid briefly touches the esophagus and rises quickly. The tissues of the throat are more sensitive to acid than the esophagus, so even small amounts can cause significant symptoms.

Root Cause Approach to Reflux

Conventional medicine often treats reflux with proton-pump inhibitors (PPIs) or antacids. While these can provide symptom relief, they do not address why reflux is occurring in the first place.

From a naturopathic perspective, reflux is rarely just about "too much stomach acid." Research suggests that many cases of reflux are actually caused by:

Small Intestinal Bacterial Overgrowth (SIBO)

Excess bacterial fermentation in the small intestine produces gas, increasing pressure on the lower esophageal sphincter and causing reflux.

Stress & the Gut-Brain Axis

Chronic stress impairs digestion and weakens the esophageal sphincter, contributing to reflux symptoms.

Food Sensitivities

Hidden sensitivities to gluten, dairy, or other foods can trigger inflammatory responses that weaken the esophageal lining.

Low Stomach Acid

Paradoxically, low stomach acid can cause reflux by impairing digestion and allowing bacterial overgrowth.

Hiatal Hernia

A structural issue where part of the stomach protrudes through the diaphragm, impairing the anti-reflux barrier.

Medication-Induced

Certain medications (NSAIDs, blood pressure drugs, antidepressants) can relax the esophageal sphincter.

Naturopathic Treatment Approaches

At MARM Health, our naturopathic doctors take a comprehensive approach to treating reflux by addressing the underlying causes:

Comprehensive Testing

We use functional lab tests including SIBO breath tests, food sensitivity panels, and comprehensive digestive stool analysis to identify root causes.

Herbal Antimicrobials

Evidence-based herbal formulas (like berberine, mastic gum, and oil of oregano) to address bacterial overgrowth without disrupting gut flora.

Targeted Nutrition

Personalized dietary protocols that eliminate trigger foods, support healing, and restore gut microbiome balance.

Stress Management

Techniques to support the parasympathetic nervous system and improve digestive function through mindfulness, adrenal support, and lifestyle modifications.

Lifestyle Modifications

Meal timing strategies, proper eating posture, elevation techniques, and sleep optimization to reduce reflux triggers naturally.

Key Takeaways

  • Not all reflux is the same – Acid reflux, GERD, and LPR have different symptoms and require different approaches.

  • LPR is often misdiagnosed – Silent reflux affects the throat and airways, not the chest, making it easy to miss.

  • PPIs do not fix the root cause – While helpful for symptom relief, acid-suppressing medications do not address why reflux is occurring.

  • Root cause matters – SIBO, food sensitivities, stress, and low stomach acid are common underlying factors.

  • Naturopathic medicine offers answers – A functional approach can identify and address the underlying causes of your reflux for lasting relief.
