Emetophobia (Fear of Being Sick) | Signs, Causes and Treatment
Emetophobia is an intense fear of vomiting, of being around someone who might vomit, or of feeling nauseous. It is often called a fear of being sick, and most people who have it have organised a great deal of their life around avoiding it. It is treatable, and the treatment with the best evidence is a specific form of CBT.

What is emetophobia?
Emetophobia is a specific phobia of vomiting. The fear can attach to different things: being sick yourself, seeing someone else be sick, being sick in public, or simply feeling nauseous and not knowing what will happen next.
What sets it apart from ordinary dislike is how much it organises. People with emetophobia avoid foods, restaurants, public transport, alcohol, hospitals, people who seem unwell, and situations where they could not leave quickly. Many check use-by dates repeatedly, scan their body for signs of nausea, sit near exits, or refuse to eat anything they have not prepared themselves.
At the centre of it, for most people, is uncertainty rather than vomiting itself. What is intolerable is not knowing whether you are going to be sick. Many people with emetophobia find it hard to name a specific feared consequence beyond how it would feel, not knowing how long it would last, or losing control. That is a normal feature of the condition, not a sign that the fear is irrational or that you have failed to explain it properly.
Disgust plays a larger role here than in most phobias, which is one reason the gender split is wider than in other specific phobias.
Is emetophobia a recognised condition?
Yes. It is classified in DSM-5 as a specific phobia, other type, and is referred to clinically as specific phobia of vomiting, or SPOV.
Two things about its status are worth knowing.
First, it is under-researched compared with other anxiety disorders, and there are no dedicated national treatment guidelines for it. What exists instead is a body of published CBT protocols, mainly from UK clinicians, and the evidence for that approach is reasonably good. Treatment is not guesswork, but it is not shaped by a NICE guideline in the way that OCD or panic disorder are.
Second, it is frequently misdiagnosed as OCD. The safety behaviours in emetophobia are highly ritualised, involving repeated checking, cleaning and avoidance, so the surface pattern can look identical. Emetophobia is also genuinely comorbid with OCD and generalised anxiety disorder in many people, which complicates the picture further. A proper assessment is what separates them, and it matters because the focus of treatment differs.
Despite the limited research, it is the most common specific phobia that presents for treatment.
What you may notice yourself feeling
intense anxiety at the thought of vomiting, or at any sign of nausea
disgust, which may be as prominent as fear
constant monitoring of your stomach and body for signs something is wrong
dread when someone nearby mentions feeling unwell
panic attacks, sometimes triggered by nausea itself
Signs of emetophobia
Safety and avoidance behaviours
These are usually the clearest sign, and they tend to expand over time.
avoiding specific foods, or foods you have not prepared or watched being prepared
checking use-by dates repeatedly, or throwing food away early
avoiding restaurants, takeaways, or eating anywhere unfamiliar
avoiding public transport, coaches, boats or flights
avoiding alcohol entirely, or people who have been drinking
avoiding hospitals, GP surgeries, or anyone who might be ill
staying near exits and toilets, or refusing to be far from home
excessive handwashing and cleaning
carrying anti-sickness tablets, mints, water or sick bags
avoiding pregnancy, or delaying it, because of morning sickness
One consequence deserves particular attention. Food avoidance can narrow the diet considerably, and for some people the range of foods they will eat becomes very restricted. Where that is happening, it needs assessing properly, both because nutrition matters and because the overlap with eating difficulties changes what treatment should address. If you recognise this, mention it at assessment rather than treating it as a separate problem.
Emetophobia in children
Emetophobia commonly begins in childhood, and in children it is easy to mistake for fussy eating, school anxiety or general clinginess.
Signs may include refusing food, refusing to eat at school or at friends' houses, distress at the mention of illness, reluctance to go to school during a sickness bug, frequent trips to the toilet or the school nurse, and asking repeatedly whether they are going to be sick.
Because reassurance is the natural parental response, and because reassurance maintains the fear, families often find themselves locked into a pattern that grows rather than settles. This is not a parenting failure. It is what the condition does, and it responds to treatment.
What causes emetophobia?
There is no single cause, and it is less well researched than most anxiety conditions.
It typically starts early, and it tends to persist. Common contributing factors include a distressing experience of vomiting in childhood, witnessing someone else being sick in frightening circumstances, a family history of anxiety disorders or phobias, and a naturally higher sensitivity to disgust.
For many people, though, there is no identifiable starting point, and this is worth saying plainly. Not being able to explain where a phobia came from does not make it less real or less treatable, and treatment does not require you to find the origin.
One figure captures the scope of the problem better than any theory. On average, people with emetophobia live with it for around 25 years before receiving treatment. It is not that it does not respond to help. It is that people rarely ask.

How is emetophobia treated?
The treatment with the strongest evidence is CBT with exposure. Because there is no national guideline for emetophobia specifically, the approach comes from published protocols developed by clinicians working with it directly, principally in the UK.
-
Treatment does not aim to convince you that vomiting is pleasant, or to prove you will never be sick. Neither would be true.
What it works on is your relationship with uncertainty and with bodily sensations. That means learning to tolerate not knowing whether you will vomit, rather than seeking certainty that you will not. It means testing what you expect to happen, gradually and deliberately, instead of arguing with the fear. And it means reducing the safety behaviours, because each one prevents you from discovering that you could have coped without it.
Exposure is graded and agreed together. It starts well below the level of your worst fear, and nothing happens without your agreement. Published protocols vary in length, with courses typically running to somewhere between twelve and sixteen sessions, and there is emerging work on more intensive formats delivered over a few days.
The work asks for real courage. It also tends to move faster than people expect once it starts, because the safety behaviours have usually been holding the fear in place for years.
-
Many people with emetophobia carry anti-nausea tablets, and some are prescribed them.
The clinical view of specialists in this area is that anti-sickness medication is usually unhelpful in the longer term, because it reinforces the belief that vomiting is something you must and can control. There is also no controlled trial evidence that medication treats a phobia of vomiting. SSRIs are sometimes prescribed where anxiety or depression are present alongside it, which is a different matter.
If you are taking medication prescribed for you, do not stop it on the basis of a web page. Raise it with the person who prescribed it, or with your therapist, so it can be looked at as part of the wider plan.
-
Nausea and anxiety produce overlapping physical sensations, so panic and the fear of vomiting feed each other directly. In the moment, what helps is fairly simple.
Slow your out-breath. Breathing too fast increases dizziness and nausea, which then feels like confirmation that you are about to be sick. Longer exhalations interrupt that loop.
Stay where you are if you safely can. Leaving immediately provides relief and teaches the fear that the situation was dangerous.
Let the sensation be there rather than fighting it. Panic peaks and falls on its own, usually within minutes.
There is an important caveat. If a technique becomes something you must do in order to prevent vomiting, it has quietly become another safety behaviour, and it will maintain the phobia rather than reduce it. In treatment, coping strategies are used to make exposure possible and then deliberately dropped. That distinction is easy to miss when you are managing alone, and it is one of the reasons structured treatment tends to outperform self-help here.
Support for emetophobia at Regal Private Therapy Practice
Our Clinical Psychologists provide CBT with exposure for emetophobia, for adults and for children and young people, in person in London and online across the UK.
The work starts with a full assessment, including whether OCD, generalised anxiety or restricted eating are part of the picture, because emetophobia frequently travels with them and treating it in isolation tends to disappoint.
From there it is collaborative and paced. We map the safety behaviours first, including the ones that have become invisible through habit, and reduce them at a rate you set. Nobody is confronted with anything they have not chosen.
If you have had emetophobia for years and assumed it was simply part of who you are, that is extremely common and it is not accurate.
Read more about therapy for adults, therapy for children and adolescents and cognitive behavioural therapy. If you are seeking help for a child or teenager, see therapy for children and adolescents.
If you need urgent support
If you are struggling to cope or worried about your safety, help is available now. Call 111 and select the mental health option, or contact your GP. Samaritans are available 24 hours a day on 116 123. In an emergency, call 999 or go to your nearest A&E.
If you are eating very little, or a child is, speak to a GP. This can affect physical health and should be looked at properly.
Frequently asked questions about emetophobia
-
The most useful thing is usually to stop reassuring them that they will not be sick, and to stop taking part in avoidance, such as checking food or agreeing to leave early. Both help in the moment and strengthen the phobia over time. Change this together rather than suddenly, ideally alongside their therapist. Take it seriously, and do not joke about it.
-
It responds well to treatment, and many people reach the point where the fear no longer shapes their decisions. Clinicians tend to avoid the word cured, because nobody enjoys being sick and the aim is not indifference. A realistic outcome is eating what you want, travelling where you want, and being able to feel nauseous without it becoming an emergency.
-
They are separate, though frequently confused and frequently co-occurring. Emetophobia is a specific phobia; OCD is a different condition with its own diagnostic category. The confusion arises because the safety behaviours in emetophobia, particularly checking and cleaning, look very like compulsions. Assessment establishes which is driving the pattern, and it can be both.
-
Yes. Nausea and anxiety share physical symptoms, so feeling sick can trigger anxiety, and anxiety can produce nausea. Many people with emetophobia experience panic attacks, sometimes triggered by an ordinary stomach sensation. Our page on panic attacks explains how that cycle works.
-
It is difficult to say, because it has rarely been measured directly. The one epidemiological study that asked about it specifically found a prevalence of around 0.1%, which is almost certainly an underestimate given how seldom people present for treatment. What is clearer is that it is the most common specific phobia among people who do seek help.
