Emetophobia is an intense phobia that causes overwhelming, intense anxiety pertaining to vomiting. This specific phobia can also include subcategories of what causes the anxiety, including a fear of vomiting in public, a fear of seeing vomit, a fear of watching the action of vomiting or fear of being nauseated. It is common for emetophobics to be underweight, or even anorexic, due to strict diets and restrictions they make for themselves. Some experts suggest sufferers are often victims of sexual or physical childhood abuse. The thought of someone possibly vomiting can cause the phobic person to engage in extreme behaviors to escape the perceived (and sometimes very real) threat of that particular situation, in which the phobic person will go through great lengths to avoid even potential situations that could even be perceived as “threatening”.

I have noticed that there have been disclaimers for movies to alert viewers about this phobia. These symptoms are real and very scary to the affected person. Please be considerate and understanding if you know of someone with this or any other type of phobias.
