The short explanation
It is natural for her to feel scared. A colonoscopy is a test where a thin, flexible tube with a camera is passed into the bowel through the back passage to look at the lining. It is commonly done with sedation, so many people feel relaxed or sleepy and remember little of it. The test usually takes less than an hour, and most people go home the same day. Doctors suggest colonoscopy for anaemia and weight loss because these can sometimes be caused by slow bleeding in the bowel, including from polyps or bowel cancer. The test can find the cause, and sometimes polyps can be removed during the same procedure. Knowing the cause allows the right treatment.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- The preparation, which involves drinking a liquid to clear the bowel the day before, is often the most unpleasant part. Ask for clear instructions.
- She can ask about sedation, whether a woman doctor or nurse can be present, and having you nearby before and after.
- Let the doctor know about her other conditions and medicines, especially blood thinners or diabetes medicines.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you what the colonoscopy will find. Only the test and her doctor can explain that.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Will she be sedated during the test?
- How should she prepare, and what about her regular medicines?
- Can a family member stay with her?
- When will we get the results?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 if she passes a lot of blood, has severe tummy pain, or feels faint.
Get help the same day
- Contact the hospital the same day if she has fever, severe pain or bleeding after the colonoscopy.
Book an appointment soon
- Arrange the colonoscopy as soon as the doctor suggests.
