A phobia is a type of anxiety disorder that causes an individual to experience extreme, irrational fear about a situation, living creature, place, or object.
When a person has a phobia, they will often shape their lives to avoid what they consider to be dangerous. The imagined threat is greater than any actual threat posed by the cause of terror.
Phobias are diagnosable mental disorders.
The person will experience intense distress when faced with the source of their phobia. This can prevent them from functioning normally and sometimes leads to panic attacks.
In the United States, approximately 19 million people have phobias.

The term ‘phobia’ is often used to refer to a fear of one particular trigger. However, there are three types of phobia recognized by the American Psychiatric Association (APA). These include:

Specific phobia: This is an intense, irrational fear of a specific trigger.

Social phobia, or social anxiety: This is a profound fear of public humiliation and being singled out or judged by others in a social situation. The idea of large social gatherings is terrifying for someone with social anxiety. It is not the same as shyness.

Agoraphobia: This is a fear of situations from which it would be difficult to escape if a person were to experience extreme panic, such being in a lift or being outside of the home. It is commonly misunderstood as a fear of open spaces but could also apply to being confined in a small space, such as an elevator, or being on public transport. People with agoraphobia have an increased risk of panic disorder.

Specific phobias are known as simple phobias as they can be linked to an identifiable cause that may not frequently occur in the everyday life of an individual, such as snakes. These are therefore not likely to affect day-to-day living in a significant way.

Social anxiety and agoraphobia are known as complex phobias, as their triggers are less easily recognized. People with complex phobias can also find it harder to avoid triggers, such as leaving the house or being in a large crowd.

A phobia becomes diagnosable when a person begins organizing their lives around avoiding the cause of their fear. It is more severe than a normal fear reaction. People with a phobia have an overpowering need to avoid anything that triggers their anxiety.
