Triggers are different than causes
No one really understands what causes an anxiety disorder, but it is generally thought to be caused by a combination of genetic and environmental factors. This is different than a trigger. A trigger is a person, place or thing that brings on feelings of anxiety. For example, if you are afraid of dogs, seeing a dog walking toward you might trigger your anxiety. While triggers are often different for each person, there are some triggers common to many people with anxiety.
