Emetophobia: A Serious Fear of Vomiting

How Cognitive Behavioural Therapy (CBT) Can Help

Nobody likes to vomit. It’s unpleasant, uncomfortable, and something most people would rather avoid. But emetophobiais very different from a normal dislike of vomiting. Emetophobia is a serious and often life-limiting fear of vomiting, either oneself vomiting or seeing or hearing others vomit.

Humans can vomit — and usually recover quickly afterwards. Other animals are less fortunate. Rats can’t vomit, which is why rat poison is so effective. Frogs eject their entire stomach, almost like turning out a pocket. Horses, despite grazing with their heads down all day, may die if they vomit. For humans, vomiting is generally not dangerous — yet for someone with emetophobia, the fear can feel overwhelming and catastrophic.

So what exactly is emetophobia? Is it a phobia? And can it be treated?

Is Emetophobia a Phobia?

The DSM-5 (the diagnostic manual used by mental health professionals) defines a specific phobia using several key criteria:

  • Unreasonable or excessive fear that is persistent and intense, triggered by a specific object or situation

  • Immediate anxiety response, disproportionate to actual danger

  • Avoidance or extreme distress when faced with the feared situation

  • Life-limiting impact, affecting work, school, or personal life

  • Duration of six months or more in children and adults

  • Not better explained by another disorder

Importantly, adults no longer need to recognise that their fear is irrational to receive a diagnosis.

By these criteria, emetophobia clearly fits the definition of a specific phobia — and it may be one of the most common.

What Is Emetophobia Like?

Emetophobia is an intense fear of vomiting or of vomit. For some people it is mildly distressing; for others, it can be profoundly disabling.

People with emetophobia may avoid:

  • Schools, restaurants, pubs, cafés

  • Public transport or crowded places

  • Public toilets, GP surgeries, hospitals, or clinics

  • Social gatherings involving food or alcohol

They may also avoid situations such as:

  • Pregnancy

  • Exercise

  • Taking medication

  • Eating certain foods or eating out

  • Drinking alcohol

  • Travelling

Over time, this avoidance can lead to significant weight loss, food restriction, isolation, obsessive checking or cleaning behaviours, and problematic use of alcohol or medication in an attempt to manage anxiety.

How Common Is Emetophobia?

Research suggests:

  • The average age of onset is around 9 years old

  • The average duration is approximately 22 years

  • Estimated prevalence ranges from 0.1% of the general population to 8.8% among people with a broader fear of vomiting

  • It is more common in females, particularly in childhood

Emetophobia frequently co-occurs with other conditions such as panic disorder, health anxiety, social anxiety, OCD, worry, or depression.

Despite this, emetophobia is often missed, meaning many people never receive the treatment that could significantly improve their quality of life.

What Keeps Emetophobia Going?

Common fears in emetophobia include:

  • Fear of losing control

  • Fear that vomiting will never stop

  • Fear of being unable to cope

  • Fear of humiliation or contamination

An aversive memory — such as a distressing vomiting experience in childhood — can play a key role. People may also experience vivid mental images or “flash-forwards” of vomiting in the future.

Avoidance, safety behaviours, checking, reassurance seeking, and restriction all provide short-term relief but maintain the fear long-term.

Cognitive Behavioural Therapy (CBT) for Emetophobia

There are effective treatments for emetophobia, and specialist Cognitive Behavioural Therapy (CBT) is one of the most evidence-based approaches.

CBT focuses on the links between:

  • Thoughts (including images and memories)

  • Physical sensations

  • Emotions

  • Behaviours

Treatment involves a clear structure:

  • Assessment and formulation – understanding how emetophobia developed and what maintains it

  • Targeted treatment strategies – addressing avoidance, safety behaviours, feared sensations, and distressing memories or images

  • Relapse prevention and recovery – helping people maintain progress and confidence over time

Relapse management strategies and booster sessions are often recommended to support long-term recovery.

By addressing core fears — such as loss of control or fear of endless vomiting — CBT helps people regain confidence, reduce avoidance, and return to living the life they choose.
