Anxiety Disorders: Types, Symptoms & Treatment
What Are Anxiety Disorders?
Anxiety disorders are among the most common mental health conditions in the UK, affecting approximately 1 in 10 people at any given time. While everyone experiences anxiety occasionally, anxiety disorders involve persistent, excessive worry that interferes with daily life.
Understanding anxiety disorders is crucial because they are highly treatable, yet many people suffer in silence for years before seeking help. With appropriate treatment, most people can manage their anxiety effectively and lead fulfilling lives.
Types of Anxiety Disorders
Generalised Anxiety Disorder (GAD)
GAD involves chronic, excessive worry about everyday situations. People with GAD often anticipate disaster and may be overly concerned about health, money, family, or work. The worry is difficult to control and occurs more days than not for at least six months.
Physical symptoms of GAD include restlessness, fatigue, difficulty concentrating, irritability, muscle tension, and sleep disturbances. The constant worry can make it difficult to relax and enjoy life.
Social Anxiety Disorder
Social anxiety involves intense fear of social situations and being judged by others. This goes beyond normal shyness and can significantly impact work, relationships, and daily activities. Physical symptoms may include blushing, sweating, trembling, and nausea.
People with social anxiety often avoid situations where they might be the centre of attention or fear embarrassing themselves. This avoidance can limit career opportunities and social connections.
Panic Disorder
Panic disorder involves recurrent, unexpected panic attacks—sudden periods of intense fear that reach a peak within minutes. Symptoms include heart palpitations, sweating, trembling, shortness of breath, feelings of impending doom, and fear of losing control or dying.
The fear of having another panic attack can lead to avoidance behaviours, with people restricting their activities to feel “safe.” This can significantly limit their lives.
Specific Phobias
Specific phobias involve intense, irrational fear of particular objects or situations, such as heights, flying, spiders, or enclosed spaces. The fear is out of proportion to the actual danger and leads to avoidance behaviours.
While many people dislike certain things, a phobia is diagnosed when the fear significantly interferes with daily life or causes considerable distress.
Health Anxiety
Health anxiety involves excessive worry about having a serious illness, despite medical reassurance. People with health anxiety may frequently check their bodies for signs of illness, seek repeated medical opinions, or avoid medical settings entirely.
