Emetophobia

Emetophobia is a phobia that causes overwhelming, intense anxiety pertaining to vomit. This specific phobia can also include subcategories of what causes the anxiety, including a fear of vomiting or seeing others vomit. It is common for emetophobics to be underweight or malnourished due to strict diets and restrictions they make for themselves. The thought of someone possibly vomiting can cause the phobic person to engage in extreme behaviors to escape the perceived threat of that particular situation, in which the phobic person will go to great lengths to avoid even potential situations that could even be perceived as "threatening".

Emetophobia is clinically considered an "elusive predicament" because limited research has been done pertaining to it. The fear of vomiting receives little attention compared with other irrational fears.

The event of vomiting may make anyone with this peculiar phobia flee the scene. Some may fear someone throwing up, while others may fear themselves throwing up. Some may have both. Some may have anxiety which makes them feel like they will throw up when they actually might not. People with emetophobia usually suffer from anxiety; they often may scream, cry, or if it is severe, possibly pass out when someone or something has been sick.

Complications
Emetophobics may also suffer from other complicating disorders and phobias, such as social anxiety, fear of flying and agoraphobia. These three are very common, because people who fear vomiting are often terrified of doing so, or encountering it, in a public place. Therefore, they may restrict their social activities so they avoid any situations with alcohol or dining out in restaurants. Emetophobics may also limit exposure to children for fear of germs. Females who suffer from this disorder delayed pregnancy or avoided it altogether because of the fear of morning sickness. People who have a fear of vomiting may avoid travel because of the worry about motion sickness or others experiencing it around them. They may also fear roller coasters for the same reason.

Dr. Lipsitz et al.'s findings also showed that those afflicted with emetophobia often have difficulties comfortably leading a normal life. Many find that they have problems being alone with young children, and they may also avoid social gatherings where alcohol is present. Retaining an occupation becomes difficult for emetophobics. Professions and personal goals can be put on hold due to the high anxiety associated with the phobia, and travelling becomes almost impossible for some.

In Lipsitz et al.'s survey, women afflicted with emetophobia said that they either delayed pregnancy or avoided pregnancy altogether because of the morning sickness associated with the first trimester, and if they did become pregnant, it made pregnancy difficult.

Other inhibitions on daily life can be seen in meal preparation. Many emetophobic people also have specific "rituals" for the food they eat and how they prepare it. They frequently check the freshness of the food along with washing it several times in order to prevent any potential sicknesses that they could contract from foods not handled properly. Eating out is also avoided, if possible, and when asked Lipsitz et al.'s survey, many felt they were underweight because of the strict diets that they put upon themselves. In addition, many emetophobes avoid certain foods all together due to negative memories they may have with it relating to vomiting, and often eat a limited number of foods due to feeling like a vast majority of foods aren't 'safe'.

Emetophobia and anorexia
There are some cases where anorexia is the result of a fear of vomiting instead of the typical psychological problems that trigger it. In Frank M. Datillio's clinical case study, a situation where anorexia results from emetophobia is mentioned. Datillio says, "...in one particular case report, atypical anorexia in several adolescent females occurred as a result of a fear of vomiting that followed a viral illness as opposed to the specific desire to lose weight or because of an anxiety reaction.". It is not clear that this should be termed "anorexia", however. In cases such as this, many emetophobes may also have avoidant/restrictive food intake disorder (ARFID), which is characterized by a general disinterest in food, sensory issues with food (taste, texture, look, smell) or a fear of adverse consequences from eating (vomiting or choking).

Oftentimes, this phobia is comorbid with several others, making it necessary to deal with each phobia individually in order for the patient to recover fully. For example, it is common for emetophobics to also suffer from a fear of food, known as cibophobia, where the sufferer worries that the food they are eating is carrying pathogens that can cause vomiting. As such, people will develop specific behaviors that will, in their minds, make the food safe to eat, such as a ritualistic type of washing or the intentional overcooking of meat to avoid the intake of harmful pathogens. In time, these fears can become so ingrained that the person who has them can begin to suffer from anorexia nervosa. Again, it is not clear that this should be deemed "anorexia" rather than, for instance OCD, given this different presentation.

Causes
There is a strong agreement in the scientific community that there is no specific cause of emetophobia. Some emetophobics report a traumatic experience with vomiting, always in childhood. Some suggest that sufferers are victims of childhood abuse – sexual or physical. While this is occasionally true, it seems to be no more prevalent than in the general population (Christie, 2004). Some experts believe that emetophobia may be linked to worries about lack of control. Many people try to control themselves and their environment in every possible way, but vomiting is difficult or impossible to control which can lead to anxiety or in other cases severe anxiety.

There are many factors that can cause a legitimate case of emetophobia. Dr. Angela L. Davidson et al. conducted an experiment where it was concluded through various surveys that people suffering from emetophobia are more likely to have an internal locus of control pertaining to their everyday life as well as health-related matters. A locus of control is an individual's perception of where control comes from. Having an internal locus of control means that an individual perceives that they have their own control over a situation, whereas an external locus of control means that an individual perceives that some things are out of their control. She explains how this phobia is created through the locus of control by stating, "Thus far, it seems reasonable to stipulate that individuals with a vomiting phobia deem events as being within their control and may therefore find it difficult to relinquish this control during the act of vomiting, thus inducing a phobia."

In an internet survey conducted by Dr. Joshua D. Lipsitz et al. given to emetophobic people, respondents gave many different reasons as to why they became emetophobic. Among some of the causes listed were several severe bouts of vomiting as children and being firsthand witnesses to many severe vomiting in others due to illness, pregnancy or alcoholism.

Assessment
There are two assessment tools used to diagnose emetophobia: the Specific Phobia of Vomiting inventory an d the Emetophobia Questionnaire. They are self-report questionnaires that focus on a different range of symptoms.

There have been a limited number of studies in regard to emetophobia. Victims of the phobia usually experience fear before vomiting but feel less afterwards. The fear comes back, however, if the victim fears they will throw up again.

Medications
Also noted in the emetophobia internet survey was information about medications. People were asked whether they would consider taking anxiety medication to potentially help their fear, and many in the study answered they wouldn't for fear that the drugs would make them nauseated. Others, however, stated that some psychotropic medications (such as benzodiazepines and antidepressants) did help with their phobia, and some said gastrointestinal medications were also beneficial.

Exposure treatments
Exposure methods, using video-taped exposure to others vomiting, hypnosis, exposure to nausea and exposure to cues of vomiting, systemic behavior therapy, psychodynamic and psychotherapy have also shown positive effects for the treatment of emetophobia. However, in some cases it may cause re-traumatization, and the phobia may become more intense as a result.

Etymology
The root word for emetophobia is "emesis", from the Greek word emein, which means "an act or instance of vomiting", with "-phobia" meaning "an exaggerated usually inexplicable fear of a particular object, class of objects, or situation."

People with emetophobia frequently report a vomit related traumatic event, such as a long bout of stomach flu, accidentally vomiting in public or having to witness someone else vomit, as the start of the emetophobia. They may also be afraid of hearing that someone is feeling like vomiting or that someone has vomited, usually in conjunction with the fears of seeing someone vomit or seeing vomit.
