What to Expect During a GERD Diagnosis and Testing
Gastroesophageal reflux disease (GERD) is a chronic digestive disorder that affects millions of people. If you experience frequent heartburn, acid reflux, or difficulty swallowing, your doctor may recommend GERD testing to confirm the diagnosis and determine the best treatment.
At Tampa Bay Reflux Center, we specialize in comprehensive GERD testing and advanced reflux treatments. Understanding the diagnostic process can help you feel more prepared and confident when seeking care.
Signs You May Need GERD Testing
GERD symptoms range from mild discomfort to severe complications. If you experience any of the following symptoms regularly, GERD testing may be necessary:
Frequent heartburn (burning sensation in the chest)
Acid reflux (regurgitation of stomach contents)
Chronic cough or sore throat
Difficulty swallowing (dysphagia)
Hoarseness or voice changes
Chest pain not related to the heart
Feeling of a lump in the throat
If left untreated, GERD can lead to serious complications, including esophageal damage, ulcers, and Barrett’s esophagus, a condition that increases the risk of esophageal cancer (Gyawali et al., 2018).
How Is GERD Diagnosed?
GERD diagnosis typically involves a combination of clinical evaluation, symptom assessment, and diagnostic testing. Here is what to expect:
Initial Consultation and Symptom Assessment
Your gastroenterologist will begin by reviewing your medical history and symptoms. Since GERD symptoms often overlap with other conditions, your doctor may use a GERD questionnaire (GERD-Q) to evaluate symptom severity (Chunlertrith et al., 2014).
Key questions include:
How often do you experience heartburn or regurgitation?
Do symptoms worsen after meals or lying down?
Have over-the-counter antacids provided relief?
If symptoms strongly suggest GERD, your doctor may recommend an empirical treatment trial with proton pump inhibitors (PPIs). If symptoms persist, further testing is needed.
Diagnostic Tests for GERD
If GERD symptoms continue or complications are suspected, your doctor may recommend one or more of the following GERD tests.
A. Esophagogastroduodenoscopy (EGD) – Upper Endoscopy
Purpose: To visually inspect the esophagus and stomach for inflammation, ulcers, or damage.
How it works:
A thin, flexible tube with a camera is inserted through the mouth.
It allows direct visualization of the esophageal lining.
Biopsies (small tissue samples) may be taken to check for Barrett’s esophagus or other abnormalities.
Why it is important:
Helps diagnose erosive esophagitis (inflammation of the esophagus).
Can rule out other conditions like ulcers or infections.
Best for patients with chronic GERD symptoms or alarm signs like weight loss or difficulty swallowing.
B. 24-Hour Ambulatory pH Monitoring
Purpose: To measure acid levels in the esophagus over 24 hours and confirm excessive acid reflux.
How it works:
A small catheter is inserted through the nose into the esophagus.
The patient wears a portable pH monitor for 24 hours.
Data is recorded to determine how often acid reflux occurs.
Why it is important:
Considered the gold standard test for diagnosing GERD (Patti et al., 2001).
Helps identify acid reflux episodes that may not be seen on endoscopy.
Essential for patients with atypical GERD symptoms like chronic cough or asthma.
C. High-Resolution Esophageal Manometry
Purpose: To assess the muscle function of the esophagus and the lower esophageal sphincter (LES).
How it works:
A thin tube is inserted into the esophagus to measure pressure and contractions.
Helps determine if the LES is weak or not functioning properly.
Why it is important:
Useful for evaluating swallowing disorders and ruling out motility issues.
Can help determine if GERD is caused by a weak esophageal sphincter.
D. Mucosal Impedance Testing
Purpose: To measure esophageal lining damage caused by acid reflux.
How it works:
A minimally invasive probe measures esophageal tissue changes.
Helps differentiate GERD from non-GERD conditions (Ateş et al., 2015).
Why it is important:
Provides higher accuracy than traditional pH monitoring.
Beneficial for patients with persistent GERD symptoms despite medication.
What Happens After GERD Testing?
Once GERD is confirmed, your doctor at Tampa Bay Reflux Center will develop a personalized treatment plan based on your test results.
Lifestyle Modifications
Avoid trigger foods (spicy, fatty, acidic foods).
Eat smaller meals and avoid lying down after eating.
Maintain a healthy weight and elevate the head of your bed.
Medication Management
Proton pump inhibitors (PPIs) to reduce acid production.
H2 blockers for mild acid reflux control.
Antacids for quick relief of occasional heartburn.
Advanced Treatment Options
For patients with severe GERD or those who do not respond to medication, Tampa Bay Reflux Center offers advanced treatment options, including:
LINX® Reflux Management System (a small device placed around the LES to prevent reflux).
Nissen Fundoplication (a surgical procedure to reinforce the LES).
Endoscopic Treatments for non-surgical relief.
