People with specific phobias have strong, irrational fears to common situations, places, or objects. Phobias commonly occur around animals, insects, driving, flying, public transportation, heights, being in small spaces, and having medical or dental treatment. The intense desire to avoid the phobia can cause problems for people in their work, school, or personal functioning.
Somewhat different, Blood, Injury, Injection (BII) Phobia is a phobia wherein people faint at the experience or prospect of seeing their own or someone else’s blood, an injury, or an injection. This can cause problems as people with BII can avoid important medical or dental care to avoid fainting during the treatment or procedure.
