Sometimes anxiety is so severe it causes a great deal of distress. It can interfere with the ability to function in society. In these cases, an anxiety disorder is said to be present.
What are the causes and risks of the condition?

Anxiety disorders are not caused by other medical conditions. It is not known why some people are more anxious than others. The feeling of anxiety is caused by the body's defense mechanisms. This is called fight or flight. The body makes adrenaline, which causes the symptoms.
