24-Hour Esophageal pH Monitoring
Dr. (Brig) Pankaj Puri offers 24-hour esophageal pH monitoring at Fortis Escorts Liver and Digestive Diseases Institute, Okhla. This advanced diagnostic test accurately measures acid reflux over a full day, helping determine whether persistent heartburn, chest discomfort, chronic cough, or throat irritation is caused by gastroesophageal reflux disease (GERD).
During the test, a thin, flexible catheter is gently placed through the nose into the lower esophagus. It continuously records acid exposure for 24 hours while you carry out your normal daily activities. The results provide detailed information about how often acid reflux occurs, how long it lasts, and whether it matches the symptoms you experience.
Considered one of the most reliable tests for confirming GERD, 24-hour pH monitoring helps guide the most appropriate treatment plan and is especially valuable when endoscopy results are normal or before anti-reflux surgery.
When Is 24-Hour pH Metry Recommended?
Your gastroenterologist may recommend 24-hour esophageal pH monitoring in the following situations.
Persistent Heartburn
For heartburn or chest discomfort that continues despite treatment with acid-reducing medications.
Normal Endoscopy with Reflux Symptoms
When endoscopy appears normal but GERD is still strongly suspected and needs confirmation.
Chronic Cough or Hoarseness
To determine whether long-term cough, hoarseness, or throat irritation is related to acid reflux.
Non-Cardiac Chest Pain
For chest pain after heart-related causes have been ruled out and reflux is suspected.
Before Anti-Reflux Surgery
To confirm the diagnosis of GERD before planning anti-reflux procedures or surgery.
How the 24-Hour pH Metry Test Works
The 24-hour esophageal pH monitoring test is a simple outpatient procedure performed without sedation. It continuously measures acid exposure in the lower esophagus while you go about your normal daily routine, helping your gastroenterologist accurately diagnose gastroesophageal reflux disease (GERD) and correlate reflux episodes with your symptoms.
- A thin, flexible catheter with a pH sensor is gently passed through the nose into the lower esophagus.
- The catheter is connected to a small portable recorder that you carry throughout the day.
- You continue your normal activities, including eating, working, and sleeping.
- You record meal times, symptoms, and periods of lying down using the recorder.
- The recorded information helps match symptoms with acid reflux episodes.
- After 24 hours, the catheter is removed and the collected data is analyzed by your gastroenterologist.
Preparing for the 24-Hour pH Metry Test
Proper preparation helps ensure accurate results from your 24-hour esophageal pH monitoring test. Your gastroenterologist will provide specific instructions based on your condition and current medications before the procedure.
- Fast for several hours before the catheter is inserted, as instructed by your doctor.
- You may be asked to stop acid-reducing medications such as proton pump inhibitors (PPIs) about a week before the test if untreated reflux is being assessed.
- Continue your normal daily routine during the 24-hour recording period to obtain accurate results.
- Inform your doctor about all current medications, allergies, or any nasal and sinus conditions before the procedure.
- Wear comfortable clothing, as you will carry a small portable recording device throughout the test.
- Carefully record your meals, symptoms, and sleeping times to help correlate reflux episodes with your daily activities.
Understanding Your 24-Hour pH Metry Results
After the 24-hour monitoring period, the recorded data is carefully analyzed to determine how often acid reflux occurred, how long each episode lasted, and whether the reflux episodes matched the symptoms you recorded. These findings help your gastroenterologist accurately diagnose GERD, assess its severity, and recommend the most appropriate treatment based on objective evidence.
- Measures the frequency and duration of acid reflux episodes.
- Matches reflux events with your recorded symptoms.
- Confirms whether GERD is responsible for your symptoms.
- Helps determine the severity of acid reflux disease.
- Guides decisions on medications, lifestyle changes, or anti-reflux procedures.
- Identifies when symptoms may be caused by conditions other than acid reflux.

Frequently Asked Questions
Find answers to common questions about 24-hour esophageal pH monitoring, including the procedure, preparation, comfort, and what to expect during the test.
24-hour pH metry is a diagnostic test that continuously measures acid levels in the esophagus over a 24-hour period using a thin, flexible catheter. It helps confirm whether symptoms are caused by acid reflux and determines the severity of GERD.
The catheter placement may cause mild, temporary discomfort in the nose or throat, but the procedure does not require sedation. Most patients tolerate the test well and continue their normal daily activities without difficulty.
You will usually be asked to fast for several hours before the procedure. Depending on your condition, your doctor may also advise stopping acid-reducing medications for about a week before the test to obtain accurate results.
Yes. You are encouraged to eat, work, walk, and sleep as you normally would while wearing the portable recorder. Recording your meals, symptoms, and activities helps your doctor accurately match acid reflux episodes with your symptoms.
