Fear of Medical Procedures

Iatrophobia

One American in three avoids going to the doctor even when they think they need to, and the extreme form of that has a name, iatrophobia, with no prevalence figure attached to it at all. The two facts belong to the same subject and are never reported together.

What medical fear covers

Medical fear has a formal definition: any experience that involves medical personnel or procedures in the process of evaluating or modifying health status in traditional health care settings. That is deliberately wide, because the specific fears underneath it are usually met together rather than singly:

Most of it is not a clinical problem. The encyclopedic account notes that these fears are seldom diagnosed or treated because they are usually extinguished by adulthood and do not often develop into phobias that stop people seeking care.

The classification is the blood, injection and injury type, one of the five subtypes of specific phobia, and the one with its own physiology: the reaction that ends in fainting rather than flight.

Why iatrophobia has never been counted

Iatrophobia is the extreme form, an intense fear of medical attention persisting even in the presence of signs of serious illness, from the Greek iatros, a healer.

No prevalence figure exists for it. What exists instead is a figure for the ordinary version: a survey found that one American in three avoids going to the doctor even when they consider it necessary. The sources also note that rates of iatrophobia probably rose after the COVID-19 pandemic, during which people with it avoided testing and avoided presenting with symptoms.

The gap between those two numbers is where the entry sits. A third of a population declining care they believe they need is a public health figure of considerable size, and the clinical term for the severe end of it has never been counted.

What the tomophobia case shows

Tomophobia is the narrower term, for fear or anxiety caused by forthcoming surgery or medical intervention, and it has a case. A 69-year-old man refused an urgently indicated medical intervention because of severe tomophobia.

The paper's argument follows from the case rather than decorating it: given the rising number of surgical interventions in modern medicine and the number of unrecognised cases, it describes tomophobia as a common but underdiagnosed anxiety disorder that should be highlighted.

A fear whose consequence is refusing an urgent procedure is not a fear of an object. It is a decision, made under distress, with an outcome.

What the virtual reality review found

Aysenur Kilic and colleagues at King's College London reviewed the use of virtual reality against this family of fears, searching four databases to October 2020 and selecting 28 studies. The technology was used in three different ways across them: as distraction, as hypnosis and as exposure, applied to needle phobia, dental phobia, Claustrophobia during scans and anxiety during burn wound care.

Their finding is two-sided and the second half is the important one. Virtual reality does reduce fear of medical procedures in some situations, and its effectiveness for blood-injection-injury phobias and for burn wound care patients was unclear. Their risk-of-bias assessment found poor study quality across the whole set, which limits any firm general conclusion.

That is a review reporting that the treatment works and that the evidence it works is weak, in the same paragraph.

Where the children's fear comes from

A cross-sectional study published in 2025 measured 150 hospitalised children aged six to twelve, admitted with acute or chronic illness and accompanied by their mothers, using a Medical Procedure Fear Scale. Their mean score was 52.9.

The finding the authors draw out is that psychosocial symptoms significantly predict medical fear, and their recommendation names the mechanism: strategies are needed to reduce the fear that arises from uncertainty during a hospital stay. Not from the procedures. From not knowing what is going to happen.

Common questions

Questions about Iatrophobia

How many people avoid medical care out of fear?
A survey found one American in three avoids going to the doctor even when they consider it necessary. That figure is for ordinary avoidance rather than for iatrophobia, which has no prevalence figure at all.
What is tomophobia?
The narrower term, for fear or anxiety about a forthcoming surgical or medical intervention. It is the one with a published case: a 69-year-old man who refused an urgently indicated procedure. The paper describing him calls the condition common and underdiagnosed and argues it needs highlighting.
Does virtual reality treatment work?
In some situations, and the evidence is weak. A systematic review of 28 studies found virtual reality effective for reducing fear of medical procedures when used for distraction, hypnosis or exposure, found its effect on blood-injection-injury phobias and burn wound care unclear, and reported poor study quality across the whole set.
Do children grow out of it?
Usually. The encyclopedic account notes these fears are seldom diagnosed or treated because they are generally extinguished by adulthood and do not often develop into phobias that prevent people seeking care. The minority who do not are what the clinical terms are for.
What actually frightens children in hospital?
Not the procedures, on the evidence. A 2025 study of 150 hospitalised children aged six to twelve found psychosocial symptoms significantly predicted medical fear, and its recommendation is aimed at the fear arising from uncertainty during the stay rather than from anything done to them.
