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.
Anxiety is the main symptom of several conditions, including:
However, 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 one specific event.
People with GAD feel anxious most days and often struggle to remember the last time they felt relaxed. As soon as one 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:
Although feelings of anxiety at certain times are completely normal, see your doctor if anxiety is affecting your daily life or causing you distress.
Your doctor will ask about your symptoms and your worries, fears and emotions to find out if you could have GAD.
The exact cause of GAD isn't fully understood, although it's likely that a combination of factors plays a role. Research has suggested that these may include:
However, 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 common 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. These include:
There are also many things you can do yourself to help reduce your anxiety, such as:
With treatment, many people are able to control their anxiety levels. However, some treatments may need to be continued for a long time and there may be periods when your symptoms worsen.
Generalised anxiety disorder (GAD) can affect you both physically and mentally.
How severe the symptoms are varies from person to person. Some people have only one or two symptoms, while others have many more.
You should see your doctor if anxiety is affecting your daily life or is causing you distress.
GAD can cause a change in your behaviour and the way you think and feel about things, resulting in symptoms such as:
Your symptoms may cause you to withdraw from social contact (seeing your family and friends) to avoid feelings of worry and dread.
You may also find going to work difficult and stressful, and may take time off sick. These actions can make you worry even more about yourself and increase your lack of self-esteem.
GAD can also have a number of physical symptoms, including:
For example, if you have claustrophobia (fear of confined spaces) , you know that being confined in a small space will trigger your anxiety.
However, if you have GAD, it may not always be clear what you're feeling anxious about. Not knowing what triggers your anxiety can intensify it and you may start to worry that there's no solution.
See your doctor if anxiety is affecting your daily life or is causing you distress.
Generalised anxiety disorder (GAD) can be difficult to diagnose. In some cases, it can also be difficult to distinguish from other mental health conditions, such as depression.
You may have GAD if:
Your doctor may ask you questions about:
You may find it difficult to talk about your feelings, emotions and personal life. However, it's important that your doctor understands your symptoms and circumstances, so the correct diagnosis can be made.
You're most likely to be diagnosed with GAD if you've had symptoms for six months or more. Finding it difficult to manage your feelings of anxiety is also an indication that you may have the condition.
To help with the diagnosis, your doctor may carry out a physical examination or blood tests to rule out other conditions that may be causing your symptoms, such as:
Generalised anxiety disorder (GAD) is a long-term condition, but a number of different treatments can help.
Before you begin any form of treatment, your doctor should discuss all your treatment options with you. They should outline the pros and cons of each and make sure you're aware of any possible risks or side effects.
With your doctor, you can make a decision on the most suitable treatment, taking into account your personal preferences and circumstances.
At first, your doctor may suggest trying an individual self-help course for a month or two, to see if it can help you learn to cope with your anxiety.
This usually involves working from a book or computer programme on your own (you'll be given advice before you start), with only occasional contact with your doctor.
Alternatively, you may prefer to go on a group course where you and a few other people with similar problems meet with a therapist every week to learn ways to tackle your anxiety.
See self-help tips for anxiety for more information on these treatments.
If these initial treatments don't help, you'll usually be offered either a more intensive psychological treatment or medication. These are described below.
If you've been diagnosed with GAD, you'll usually be advised to try psychological treatment before you're prescribed medication.
Cognitive behavioural therapy (CBT) is one of the most effective treatments for GAD. Studies of different treatments for GAD have found that the benefits of CBT may last longer than those of medication, but no single treatment is best for everyone.
CBT helps you to understand how your problems, thoughts, feelings and behaviour affect each other. It can also help you to question your negative and anxious thoughts, and do things you would usually avoid because they make you anxious.
CBT usually involves meeting with a specially trained and accredited therapist for a one-hour session every week for three to four months.
Your therapist should carry out CBT in a standardised way according to a treatment manual, and they should receive regular supervision to support them in providing the most effective treatments.
Mindfulness and applied relaxation are alternative types of psychological treatment that can be as effective as CBT in treating GAD.
Mindfulness works by focusing your awareness on the present moment and by acknowledging and accepting certain feelings. Being mindful can reduce anxiety caused by the fear of actual situations or sensations, or anticipated ones. It helps to counter the sense of "tunnel vision" that may develop during anxiety. Although mindfulness originates from Buddhism, it doesn't require you to change or take on any religious beliefs.
Applied relaxation focuses on relaxing your muscles in a particular way during situations that usually cause anxiety. The technique needs to be taught by a trained therapist, but generally involves:
As with CBT, applied relaxation therapy will usually mean meeting with a therapist for a one-hour session every week for three to four months.
If the psychological treatments above haven't helped or you would prefer not to try them, you'll usually be offered medication.
Your doctor can prescribe a variety of different types of medication to treat GAD. Some medication is designed to be taken on a short-term basis, while other medicines are prescribed for longer periods.
Depending on your symptoms, you may need medicine to treat your physical symptoms, as well as your psychological ones.
If you're considering taking medication for GAD, your doctor should discuss the different options with you in detail before you start a course of treatment, including:
You should also have regular appointments with your doctor to assess your progress when you're taking medication for GAD. These will usually take place every two to four weeks for the first three months, then every three months after that.
Tell your doctor if you think you may be experiencing side effects from your medication. They may be able to adjust your dose or prescribe an alternative medication.
The main medications you may be offered to treat GAD are described below.
In most cases, the first medication you'll be offered will be a type of antidepressant](/condition/antidepressant-drugs) called a [selective serotonin reuptake inhibitor (SSRI) . This type of medication works by increasing the level of a chemical called serotonin in your brain.
Examples of SSRIs you may be prescribed include:
SSRIs can be taken on a long-term basis but, as with all antidepressants, they can take several weeks to start working. You'll usually be started on a low dose, which is gradually increased as your body adjusts to the medicine.
Common side effects of SSRIs include:
These side effects should improve over time, although some – such as sexual problems – can persist.
If your medication isn't helping after about two months of treatment, or if it's causing unpleasant side effects, your doctor may prescribe an alternative SSRI.
When you and your doctor decide it's appropriate for you to stop taking your medication, you'll normally have your dose slowly reduced over the course of a few weeks to reduce the risk of withdrawal effects. Never stop taking your medication unless your doctor specifically advises you to.
If SSRIs don't help ease your anxiety, you may be prescribed a different type of antidepressant known as a serotonin and noradrenaline reuptake inhibitor (SNRI). This type of medicine increases the amount of serotonin and noradrenaline in your brain.
Examples of SNRIs you may be prescribed include:
Common side effects of SNRIs include:
SNRIs can also increase your blood pressure, so your blood pressure will be monitored regularly during treatment.
As with SSRIs, some of the side effects – such as feeling sick, an upset stomach, problems sleeping and feeling agitated or more anxious – are more common in the first one or two weeks of treatment, but these usually settle as your body adjusts to the medication.
If SSRIs and SNRIs aren't suitable for you, you may be offered pregabalin. This is a medication known as an anticonvulsant, which is used to treat conditions such as epilepsy . However, it's also been found to be beneficial in treating anxiety.
Side effects of pregabalin can include:
Pregabalin is less likely to cause nausea or a low sex drive than SSRIs or SNRIs.
Benzodiazepines are a type of sedative that may sometimes be used as a short-term treatment during a particularly severe period of anxiety, because they help ease the symptoms within 30 to 90 minutes of taking the medication.
If you're prescribed a benzodiazepine, it will usually be diazepam.
Although benzodiazepines are very effective in treating the symptoms of anxiety, they can't be used for long periods of time because they can become addictive if used for longer than four weeks. Benzodiazepines also start to lose their effectiveness after this time.
For these reasons, you won't usually be prescribed benzodiazepines for any longer than two to four weeks at a time.
Side effects of benzodiazepines can include:
As drowsiness is a particularly common side effect of benzodiazepines, your ability to drive or operate machinery may be affected by taking this medication. You should avoid these activities during treatment.
If you've tried the treatments mentioned above and have significant symptoms of GAD, you may want to discuss with your doctor whether you should be referred to a mental health specialist.
A referral will work differently in different areas of the UK, but you'll usually be referred to your community mental health team. These teams include a range of specialists, including:
An appropriate mental health specialist from your local team will carry out an overall reassessment of your condition. They'll ask you about your previous treatment and how effective you found it.
They may also ask about things in your life that may be affecting your condition, or how much support you get from family and friends.
Your specialist will then be able to devise a treatment plan for you, which will aim to treat your symptoms.
As part of this plan, you may be offered a treatment you haven't tried before, which might be one of the psychological treatments or medications mentioned above.
Alternatively, you may be offered a combination of a psychological treatment with a medication, or a combination of two different medications.
If you have generalised anxiety disorder (GAD), there are many ways to help ease the symptoms of anxiety yourself.
When you're diagnosed with GAD, your doctor may recommend trying self-help treatments before having more intensive psychological therapy or medication.
This usually involves working from a book or computer programme for around six weeks or longer. In some cases, you may be closely supported by a trained therapist who you'll speak to every week or two. Some treatments only involve minimal or occasional contact with a therapist, who monitors your progress.
There are numerous books and courses that can help you learn to cope with your anxiety, but the National Institute for Health and Care Excellence (NICE) only recommends trying treatments based on the principles of cognitive behavioural therapy (CBT) .
CBT is a type of psychological treatment that can help you understand your condition better and how your problems, thoughts, feelings and behaviour affect each other. The aim of CBT-based treatments is to help you learn ways to manage your anxiety by modifying negative or unhelpful thoughts and behaviour.
Regular exercise, particularly aerobic exercise, may help you combat stress and release tension. It also encourages your brain to release serotonin, which can improve your mood.
Examples of good aerobic exercises include:
You should aim to do at least 150 minutes of moderate-intensity exercise a week. Moderate-intensity exercise should raise your heart rate and make you breathe faster.
As well as regular exercise, learning how to relax is important.
You may find relaxation and breathing exercises helpful, or you may prefer activities such as yoga or pilates to help you unwind.
Drinking too much caffeine can make you more anxious than normal. This is because caffeine can disrupt your sleep and also speed up your heartbeat. If you're tired, you're less likely to be able to control your anxious feelings.
Avoiding drinks containing caffeine – such as coffee, tea, fizzy drinks and energy drinks – may help to reduce your anxiety levels.

Smoking and alcohol have been shown to make anxiety worse. Only drinking alcohol in moderation or stopping smoking may help to reduce your anxiety.
To reduce the risk of harming your health:
Fourteen units is equivalent to six pints of average-strength beer or 10 small glasses of low-strength wine.
Read how stopping smoking can reduce your anxiety.
Support groups can give you advice on how to manage your anxiety. They are also a good way to meet other people with similar experiences.
Support groups can often arrange face-to-face meetings, where you can talk about your difficulties and problems with other people. Many support groups also provide support and guidance over the phone or in writing.
Ask your doctor about local support groups for anxiety in your area, or search online for mental health information and support services near you.
