blood phobia
a persistent and irrational fear of blood, specifically of seeing blood. Situations in which blood may be encountered are often avoided or else endured with intense anxiety or distress. An individual confronting blood experiences a subjective feeling of disgust and fears the consequences of the situation, such as fainting. In certain diagnostic classifications, such as DSM–IV–TR and DSM–5, blood phobia is identified as a specific phobia, blood-injection-injury type. Blood phobia rarely is called hematophobia or hemophobia.
