A 24-hour esophageal pH study is used to measure the number of acid reflux episodes a patient experiences during a 24-hour period. The study also measures the amount of time (in minutes) that stomach acid is present in the esophagus and allows for evaluation of your symptoms with activity, at home or work, and especially during sleep.
Before Your Appointment
The 24-hour esophageal pH study takes place in an examination room. You will not be asked to remove any clothing, and sedation is not usually given. Your appointment will last about an hour, including outpatient admission, instruction and placement of the pH catheter.
- The nurse will spray the inside of your throat with a topical anesthetic and will use an anesthetic lubricant on the small, flexible pH tube.
- The tube (1/8? in diameter) is gently placed into one nostril and guided into the esophagus. The end of the tube is positioned precisely 2? above the diaphragm, where acid sensing occurs.
- After the pH catheter is placed, it is secured to the end of your nose and side of your face with small pieces of silk tape.
- The catheter is attached to a "Walkman" style recorder, which is provided.
After Your Appointment
After your appointment you will be able to resume normal activities. Some patients find that the pH catheter does not interfere with their normal activities, while others find it to be annoying and choose to have someone drive them home. You will need to return to the clinic 24 hours after the procedure to have the catheter removed. Removal will only take about five minutes.
The catheter may cause:
- Watery eyes
- Runny nose
- Sore throat
Risks
24-Hour esophageal pH monitoring is a very low risk procedure, when performed by a competent specialist. Complications such as perforations (tearing) or bleeding of the gastrointestinal wall can occur, but they are rare. Equipment failure or death are extremely unlikely but remain remote possibilities.

Dr. Doherty is a very kind man and has gained my trust in him. He is genuinely concerned about his patients and their feelings. Would highly recommend him!
Very professional and accurate. I would highly recommend Dr. Friedman for his knowledge, experience, accuracy and professionalism.
Exceptional Care and Professionalism: A Review for Dr. Rajesh Manam and Team I recently underwent a procedure with Dr. Rajesh Manam and his entire team, and I cannot praise them enough. From start to finish, everyone was kind, professional, caring, and efficient. They made me feel comfortable throughout the entire process, ensuring I experienced no fear or discomfort. Interestingly, during the procedure, even though I was anesthetized, I was aware of some sensations. I could feel the procedure happening in a subtle way—without pain or full consciousness—but this didn’t bother me, as everything was handled so smoothly and professionally. The procedure was quick, and the care I received was impeccable. I had no complications afterward, and the results were excellent. Dr. Manam and his staff ensured the entire experience was as positive as possible, and I am grateful for their expertise and kindness. I would highly recommend them to anyone seeking medical care. 🐞
Fast and easy, down to earth
