Esophageal Manometry or Reflux Monitoring: What Does Each Measure?

Two test names on an appointment letter can leave you unsure how much of the day to set aside. Ask which tests are booked and what each is meant to answer. Keep that explanation beside the preparation instructions.

Manometry examines movement

A thin tube passes through the nose into the esophagus and stomach. You swallow while the team records how the esophagus works. UCLH describes removing this catheter after the measurements, before a separate reflux catheter is placed when both studies are planned.¹

Reflux monitoring records events over time

A pH-and-impedance catheter measures acidity and movement of fluid or air. It stays connected to a small recorder during the monitoring period. UCLH describes going home with it for a 24-hour recording. Ask whether your booked study uses this method or another system.¹

If having a visible tube affects your plans for work or a shared meal, bring that up before the appointment. Ask the team how to arrange your day while following its recording instructions.

Confirm the medicine instructions

Some reflux recordings are performed while acid-reducing medicines continue. Others require specified medicines to be withheld. UCLH provides separate instructions for those two plans. Follow your own testing unit’s directions and call about conflicting instructions before changing treatment.¹²

Write down the exact medicine names when you call. Ask about eating and drinking before the visit, how symptoms should be recorded and who will explain the results. Put the return appointment or equipment instructions in the same folder.

Bloated by Dinner includes a Belly Clock log and a visit script. Use them to organize digestive observations and questions alongside the testing team’s instructions. See the book.
