Social Anxiety Disorder, also known as social phobia, is a type of anxiety disorder that causes extreme fear in social settings. People with Social Anxiety Disorder have trouble talking to people, meeting new people and attending social gatherings. They fear being judged or scrutinized by others. They may understand that their fears are irrational or unreasonable, but feel powerless to overcome them. Social anxiety is different from shyness. Shyness is usually short-term and doesn’t disrupt one’s life. Social anxiety is persistent and debilitating. It can affect one’s ability to:
• work
• attend school
• develop close relationships with people outside of their family

Social interaction may cause the following physical symptoms:
• blushing
• nausea
• excessive sweating
• trembling or shaking
• difficulty speaking
• dizziness or lightheadedness
• rapid heart rate
Psychological symptoms may include:

• worrying intensely about social situations
• worrying for days or weeks before an event
• avoiding social situations or trying to blend into the background if you must attend
• worrying about embarrassing yourself in a social situation
• worrying that other people will notice you are stressed or nervous
• missing school or work because of anxiety
It is normal to sometimes feel anxious. However, when you have social phobia, you have a constant fear of being judged by others or humiliated in front of them. You may avoid all social situations, including:
• asking a question
• job interviews
• shopping
• using public restrooms
• talking on the phone
• eating in public
Symptoms of social anxiety may not occur in all situations. You can have limited or selective anxiety. For example, symptoms may only occur when you’re eating in front of people or talking to strangers. Symptoms can occur in all social settings if you have an extreme case.

What Causes Social Anxiety Disorder?
The exact cause of social phobia is unknown. However, current research supports the idea that it is caused by a combination of environmental factors and genetics. Negative experiences also may contribute to this disorder, including:
• bullying
• family conflict
• sexual abuse
Physical abnormalities such as a serotonin imbalance may contribute to this condition. Serotonin is a chemical in the brain that helps regulate mood. An overactive amygdala (a structure in the brain that controls fear response and feelings or thoughts of anxiety) may also cause these disorders.
Anxiety disorders can run in families. However, researchers aren’t sure if they’re actually linked to genetic factors. For example, a child might develop an anxiety disorder by learning the behavior of one of their parents who has an anxiety disorder. Children can also develop anxiety disorders as a result of being raised in controlling or overprotective environments.

Diagnosing Social Anxiety Disorder

There is no medical test to check for social anxiety disorder. Your healthcare provider will diagnose social phobia from a description of your symptoms. They can also diagnose social phobia after examining certain behavioral patterns.
During your appointment, your healthcare provider will ask you to explain your symptoms. They will also ask you to talk about situations that cause your symptoms. The criteria for social anxiety disorder includes:
• a constant fear of social situations due to fear of humiliation or embarrassment
• feeling anxious or panicky before a social interaction
• a realization that your fears are unreasonable
• anxiety that disrupts daily living
