It is an extremely common phobia - research suggests that as many as 3.5 million people in the UK alone have emetophobia and yet it remains a relatively unknown and misunderstood condition.
Emetophobia may be referred to as a Specific Phobia of Vomiting (SPOV). It may also be associated with other anxiety disorders including phagophobia (fear of gagging/choking) or tocophobia (fear of pregnancy)
Sufferers may be put off getting pregnant or may terminate a pregnancy due to an extreme fear of morning sickness - those who do go through with a pregnancy may struggle with the idea that their baby may become ill.
Those with the condition will often go to extreme lengths to avoid the possibility of getting sick such reducing the amount of food they eat, not drinking too much, avoiding eating out or places were people might over indulge or drink heavily such as pubs, nightclubs parties and so on.
Those with emetophobia worry a great deal about health and hygiene - they are extremely vigilant with regards food preparation and will take excessive care to check 'use by' and 'sell by' dates on food packaging.
Those with the condition worry constantly about germs and being exposed to those who may be ill or could get ill particularly if there is a bug going around.
The reasons for this vary - the sufferer may, for example feel embarrassed to talk about a condition of which they feel ashamed. It is hardly surprising therefore that so many people don't know about the condition.
Thankfully, for many, the time will come when they will seek help. Whether the help they receive will be beneficial depends however on the practitioner they choose to work with.
The condition, due to a general lack of understanding can be easily misdiagnosed which in turn can lead to treatments that are largely inappropriate and ineffectual.
Needless to say, for many, the possibility of overcoming their condition is not great ... however, all is not lost because there is an excellent, very successful, evidence-based intervention available for those with emetophobia.
Those who undertake the programme learn, not only what emetophobia is but the relationship between the condition and the sufferers personality, thinking styles and belief systems.
