GERD presents in different patterns depending on the underlying mechanisms and severity. Each type requires specific diagnostic approaches and targeted treatment strategies.
| Type | Primary Pattern | Common Symptoms | Considerations |
|---|---|---|---|
| Classical GERD | Excessive acid exposure due to LES dysfunction | Heartburn, regurgitation, chest pain | Often responds to acid reduction but may require LES strengthening |
| Functional Heartburn | Normal acid exposure with hypersensitive esophagus | Burning chest pain, PPI-refractory symptoms | Requires neuromodulation and gut-brain axis support |
| Silent Reflux (LPR) | Acid reaching throat and airways | Chronic cough, hoarseness, throat clearing | Often missed, requires different diagnostic approach |
| Complicated GERD | Structural damage from chronic acid exposure | Difficulty swallowing, bleeding, chest pain | May involve Barrett's esophagus, strictures, or ulceration |

Comprehensive GERD evaluation goes beyond symptom assessment to identify root causes and optimize treatment strategies. GERD has been treated as a condition of overproduction of acid. In reality it is a condition in which the lower esophageal sphincter, the valve which connects the esophagus to the stomach, is inappropriately open. The root cause of this can be from improper nutrition, emotional stress, and medications. At Whole Gut Health, we use advanced diagnostics and years of experience to understand the underlying mechanisms driving your reflux.
Testing options may include:

GERD (Gastroesophageal Reflux Disease) occurs when stomach acid and other contents regularly back up into the esophagus due to dysfunction of the lower esophageal sphincter (LES). While occasional acid reflux is normal, GERD represents chronic, persistent reflux that can cause tissue damage and systemic symptoms requiring comprehensive treatment.
Classical GERD
Functional Heartburn

Complicated GERD
Comprehensive GERD evaluation includes multiple testing approaches. Testing options include:
Testing protocols are customized based on your symptom pattern and medical history.
Our comprehensive three-phase GERD protocol includes:
Phase 1: Assessment and Root-Cause Identification
Phase 2: Targeted Intervention
Phase 3: Rebuilding and Prevention
Different GERD types require different treatment approaches. For example:
GERD symptoms can return if underlying root causes aren't fully addressed or if triggering factors return. This is why our protocol includes a comprehensive rebuilding and prevention phase that focuses on:
