Agoraphobia affects an estimated 0.9 percent of U.S. adults in any given year, according to the National Institute of Mental Health. Agoraphobia is considered an anxiety disorder and is characterized by an intense fear of situations where it would be difficult to escape. Specific situations that can trigger agoraphobia can include traveling by airplane, riding in elevators or being in a crowd.
Agoraphobia can become debilitating to the point where a person may not leave the house because of their anxiety.
