Agoraphobia is an anxiety disorder in which a person experiences intense fear, or a panic attack, in situations that makes them feel trapped or helpless. This fear may be triggered by an actual or anticipated situation, such as using public transportation, being in a crowd, an enclosed area, or an open space. [1]

Agoraphobia triggers

Most people with agoraphobia develop it after experiencing one or more panic attacks. This causes them to worry about having another panic attack in a place where escape may be difficult, or help would be unavailable. The resulting and persistent anxiety can have a significant effect on their quality of life.

Agoraphobia causes feelings of helplessness and isolation as individuals start to avoid places or situations that remind them of past panic attacks.

People with agoraphobia may feel unsafe in public spaces and need a companion, such as a relative or friend, to accompany and support them. It may become so overwhelming that it is difficult for them to leave home.

Several different situations can trigger agoraphobia. The most common are listed below [2]:

  • Being in a crowd or busy area,especially those with high levels of noise, such as a sports stadium
  • Traveling on public transportation
  • Hyperventilation or over breathing
  • Being in an enclosed area such as an elevator, tunnel, car or public bathroom
  • Being in open spaces such as a parking lotor shopping center
  • Being too far from home
