What causes emetophobia / Why to emetophobes fear vomiting?
Often emetophobia is caused by a traumatic incident involving vomit during one’s childhood. The individual’s mind then associates vomit with those traumatic factors, and develops a fear of vomit. Another theory suggests that kids who exhibited an extreme lack of vomiting as young children may never have become accustomed to vomiting as a normal part of life, and thus developed a phobia because it is something irregular and unknown.
