Anxiety is a feeling of unease, such as worry or fear, that can be mild or severe.
Everyone has feelings of anxiety at some pointÂ 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.
But some peopleÂ find it hard to control their worries. Their feelings of anxiety are more constant and can often affect theirÂ daily lives.
Anxiety is the main symptom of several conditions, including:
- panic disorder
- phobias,Â such asÂ agoraphobiaÂ or claustrophobiaÂ
- post-traumatic stress disorder (PTSD)
- social anxiety disorder (social phobia)
The information in this section is about a specific condition called generalised anxiety disorder (GAD).
GAD is a long-term condition that causes you to feel anxious about a wide range of situations and issues, rather than 1 specific event.Â
People with GAD feel anxious most days and often struggle to remember the last time they felt relaxed.
As soon as 1 anxious thought is resolved, another may appear about a different issue.
GAD can cause both psychological (mental) and physical symptoms.
These vary from person to person, but can include:
- feeling restless or worried
- having trouble concentrating or sleeping
- dizzinessÂ or heart palpitations
When to get help for anxiety
Although feelings of anxiety at certain times are completely normal,Â see a GP if anxiety is affecting your daily life or causing you distress.
Your GP will ask about your symptoms and your worries, fears and emotions to find out if you could have GAD.
What causes generalised anxiety disorder (GAD)?
The exact cause of GAD is not fully understood, although it's likely thatÂ a combination of several factors plays a role.
Research has suggested that these may include:
- overactivity in areas of the brainÂ involved in emotions and behaviour
- an imbalance of the brain chemicals serotonin and noradrenaline, whichÂ are involved in the control and regulation of mood
- the genes you inherit from your parentsÂ â you're estimated to be 5 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
- havingÂ aÂ painful long-term health condition, such as arthritis
- having a history of drug or alcohol misuse
But many people develop GAD for no apparent reason.
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 commonÂ in people from the ages of 35 to 59.
GAD can have a significant effect on your daily life, but several different treatments are available that can ease your symptoms.
- psychological therapiesÂ â you can get psychological therapies like cognitive behavioural therapy (CBT) on the NHS; you do not need a referral from a GP and you can refer yourself for psychological therapies service in your area
- medicine â such as a type of antidepressant calledÂ selective serotonin reuptake inhibitors (SSRIs)
With treatment, many people are able to control their anxiety levels. But some treatments may need to be continued for a long time and there may be periods when your symptoms worsen.
There are also many things you can do yourself to help reduceÂ your anxiety, such as:Â
- going onÂ a self-help course
- exercising regularly
- stopping smoking
- cutting down on the amount of alcohol and caffeine you drink
- trying 1 of the mental health apps and tools in the NHS Apps Library
