Colonoscopy and Anxiety: How Virtual Reality Eliminates Fear

The life-saving exam that everyone postpones

Colonscopy is the most effective tool to prevent colorectal cancer — the second most lethal cancer in Italy. Yet, a significant percentage of the population postpones or completely avoids it.

The reason is almost never medical. It is emotional. As we have explored in detail when discussing procedural memory and the memory that lasts, a past negative experience conditions health choices for years.

Fear of pain. Embarrassment. A sense of vulnerability. The feeling of losing control over one's body. Anyone who has had an unpleasant colonoscopy the first time often does not return for follow-up, even when the doctor recommends it.

The sedation problem

The standard solution is sedation: the patient falls asleep, feels nothing, wakes up and goes home. It works.

But it has costs:

An anesthesiologist is needed
The patient must remain under observation for 30-60 minutes afterwards
Not all centers have the resources to sedate every patient
Some patients cannot be sedated for clinical reasons
The patient loses an entire morning

The third way: present but elsewhere

Immersive therapy offers a third option between "feel everything" and "feel nothing because you are asleep."

The patient remains awake, present, cooperative. But their attention is elsewhere. They are immersed in an environment that their brain processes as real: a mountain landscape, a beach at sunset, a path in a forest.

They are not sedated. They are not "distracted" in the trivial sense of the term. They are cognitively engaged in an experience that leaves little room for signals of discomfort.

What the studies say

RCT 2025 — VR Colonoscopy vs IV Sedation:

A randomized controlled trial directly compared immersive VR with deep sedation during colonoscopy. The results: comparable pain and anxiety levels between the two groups. But the VR group did not need post-procedural recovery.

BMJ Open 2025 — VR and colonoscopy meta-analysis:

Registered protocol for a systematic review of all RCTs on VR during colonoscopy. The fact that BMJ Open publishes the protocol indicates how relevant the scientific community considers the topic.

Tunisian study 2025 (Health Science Reports):

Immersive VR during outpatient colonoscopy without sedation:

Significant reduction in perceived pain
Reduction in anxiety
Greater patient satisfaction
No adverse events

It is not just pain: it is dignity

There is an aspect of colonoscopy that is rarely talked about: vulnerability. The patient is in an exposed position, during an intimate procedure, surrounded by medical staff.

VR does not just eliminate physical pain. It eliminates the constant awareness of one's position, of one's exposed body. The patient is mentally elsewhere — and that "elsewhere" restores a degree of inner privacy that sedation alone does not always guarantee.

For the endoscopist: a cooperative patient

A relaxed patient is a patient who does not contract. Relaxed abdominal muscles make the procedure technically simpler. The endoscope advances with less resistance. Procedural time is reduced.

Who chooses VR instead of sedation

Not all patients will want VR. But for many it is the preferable option:

Those who must return to work immediately after
Those who cannot be sedated (comorbidities, allergies, frail elderly)
Those who want to drive home alone
Those who prefer to stay awake and present
Those who had negative experiences with sedation

VR does not replace sedation — it complements it. It adds an option where before there were only two choices: endure or sleep.

Changing the narrative of colonoscopy

Colonoscopy has an image problem. It is the exam that "everyone knows they should do" but "no one wants to do." The result: late diagnoses, cancers that could have been prevented.

If the experience of colonoscopy changes — if it becomes something manageable, non-traumatic — the narrative also changes. People who have a neutral or positive experience talk about it. They advise others to take the exam.

Prevention only works if people show up. Immersive therapy makes it easier to show up. With Lemons in the Room, already active in over 30 Italian healthcare facilities, the patient can face colonoscopy without sedation and without trauma — ready in 10 seconds, zero side effects.
