A Colonic Transit Study: Put the Capsule and X-Ray Plan on One Page

If you have taken the capsules and develop swelling of your face, lips, tongue or throat, seek emergency care immediately. Before taking capsules, contact the team about possible pregnancy or an allergy to gelatine or barium sulphate. If pregnancy is possible, do not take the capsules; contact the team.¹

Use one page for the instructions your own team gives you. Keep the original hospital information beside it, so your notes remain a companion to that information.

1. Write what the test is checking

A colonic transit study examines how quickly material moves through the large bowel. Swallowed capsules contain markers visible on abdominal X-rays; a radiologist assesses their position.¹

At the top of your page, leave room for the question you want answered: “What are you hoping to learn about my constipation?” Write the explanation in words you would use when telling someone at home why you need this appointment.

2. Copy the actual sequence

The Guy’s and St Thomas’ leaflet describes a multiday capsule and X-ray sequence. Ask your team to confirm your capsule dates and imaging appointments. Copy your own instructions, including whom to call about a missed step.¹

Make a separate line for each instructed step. Add the location, appointment time and practical arrangements next to it. A calendar reminder can say “check hospital instructions” so you have those instructions in front of you when the time comes.

3. Get the bowel medicine instructions in writing

The leaflet includes instructions about laxatives before, during and after the study. Ask your team to review the bowel medicines you use and give you your individual plan. Do not make changes from this checklist.¹

Bring your medication list to that conversation. Leave space to record the team’s answer beside each medicine you asked about, with the date and contact name. If the written instructions and what you remember hearing differ, ask the team to resolve that before starting.

4. Name the results contact

The leaflet says results go to the referring doctor or specialist, and patients should contact that clinician to arrange follow-up. Ask who will explain your result and how to arrange that conversation.¹

Finish the page with that person’s service name and contact details. Below them, write your two main questions. You can bring the same page to the results discussion without having to reconstruct the whole week from memory.
