Anxiety is a feeling of unease, such as worry or fear, that can be mild or severe.
Everyone has feelings of anxiety at some point in their life – for example, you may feel worried and anxious about sitting an exam, or having a medical test or job interview. During times like these, feeling anxious can be perfectly normal.
However, some people find it hard to control their worries. Their feelings of anxiety are more constant and can often affect their daily lives.

GAD is a long-term condition that causes you to feel anxious about a wide range of situations and issues, rather than one specific event.

What causes GAD?
The exact cause of GAD isn't fully understood, although it's likely that a combination of several factors plays a role. Research has suggested that these may include:
- overactivity in areas of the brain involved in emotions and behaviour
- an imbalance of the brain chemicals serotonin and noradrenaline, which are involved in the control and regulation of mood
- the genes you inherit from your parents – you're estimated to be five times more likely to develop GAD if you have a close relative with the condition
- having a history of stressful or traumatic experiences, such as domestic violence, child abuse or bullying
- having a painful long-term health condition, such as arthritis
- having a history of drug or alcohol misuse
However, many people develop GAD for no apparent reason.
Who is affected?
GAD is a common condition, estimated to affect up to 5% of the UK population.
Slightly more women are affected than men, and the condition is more common in people from the ages of 35 to 59.
How GAD is treated
GAD can have a significant effect on your daily life, but several different treatments are available that can ease your symptoms. These include:
