Generalised Anxiety Disorder

Overview

Generalised anxiety disorder (GAD) is a common condition where you feel worried or anxious most of the time, about lots of different things, and the worry is hard to switch off. Everyone feels anxious now and then — it is a normal response to stress. With GAD, the worry goes on for months, feels out of proportion to what is happening, and starts to get in the way of work, relationships, sleep and everyday life. GAD can also cause physical feelings, like a tight chest, tense muscles, a churning stomach or feeling tired all the time. It is not a sign of weakness, and it is not something you have to just live with.

Yes, it is very common. GAD is one of the most frequent anxiety problems seen in general practice — roughly 1 in 20 adults is affected at some point in their life. Many people also have times of feeling anxious without ever having a full diagnosis.

GAD can affect anyone, at any age. It often first appears in the teenage years or in the 20s and 30s, and it is a little more common in women than in men. Children can have it too, and so can older adults, although in older people the worry is sometimes hidden behind physical complaints. People who are going through a stressful period, a big life change or a long-term illness are more likely to notice symptoms.

Symptoms

Common symptoms

• Worrying about many everyday things — money, work, health, family, small tasks — most days, for six months or more
• Finding it very hard to stop or control the worry, even when you know it is out of proportion
• Feeling restless, on edge or unable to relax
• Muscle tension, especially in the shoulders, neck, jaw or back
• Trouble falling asleep or staying asleep, and feeling tired during the day
• Irritability or snapping more easily than usual
• Trouble concentrating or your mind going blank
• Feeling shaky, sweaty, dizzy or having a racing heart
• Stomach problems such as nausea, wind, or needing the toilet more often
• Avoiding situations, people or tasks because they make you anxious
• Feeling constantly alert, as if something bad might happen

Symptoms in children

• Worrying a lot about school, friends, tests, family or being away from parents
• Needing lots of reassurance and asking the same questions again and again
• Stomach aches, headaches or feeling sick that do not have a clear physical cause
• Trouble sleeping, or wanting to sleep in a parent's bed
• Being clingy, tearful or more easily upset than usual
• Finding it hard to concentrate at school, or avoiding school
• Being very hard on themselves, or being afraid of making mistakes

Symptoms in older adults

• Worry that shows up mainly as physical complaints, such as pain, tiredness or stomach upset
• Worrying about health, money, becoming a burden, or the future
• Poor sleep, low appetite or feeling restless
• Being seen as a 'worrier' or being told to stop worrying, rather than being offered help
• Anxiety that is mistaken for a physical illness, or that appears alongside one
• Loneliness, isolation or a recent loss making worry worse
• Sometimes new anxiety in later life is linked to memory changes, so it is worth mentioning to a doctor

Causes

Main causes

• GAD is not caused by one single thing. It usually comes from a mix of factors that build up over time.
• Genetics — anxiety problems can run in families, so some people are naturally more prone to feeling anxious.
• Brain chemistry — the brain systems that manage fear and stress may be more sensitive in some people.
• Life experiences — stressful events, difficult childhood experiences, bullying, bereavement or long-term pressure can trigger it.
• Personality style — people who are naturally cautious, perfectionist or who like to be in control may be more likely to develop it.
• Physical health — long-term pain, thyroid problems, heart or breathing conditions, and some medicines can cause or worsen anxiety.

Risk factors

• A close family member with an anxiety problem or depression
• Ongoing stress at work, at home, with money or in relationships
• A traumatic or very difficult life event
• Being a carer, or going through a big life change such as moving, divorce or job loss
• Having another mental health condition, such as depression
• Long-term physical illness or chronic pain
• Drinking a lot of caffeine or alcohol, or using recreational drugs
• Being socially isolated or lonely
• Having a shy or highly sensitive temperament

When to see a doctor

See a doctor urgently if:

• You have thoughts of harming yourself or ending your life — please contact emergency services or a crisis line right away
• You feel unable to keep yourself safe
• You cannot eat, drink or leave the house because of anxiety and are becoming unwell
• You have had several nights with almost no sleep
• You are using alcohol or drugs to get through the day
• You have new chest pain or severe breathlessness — treat this as a medical emergency until a doctor says otherwise

Book a routine appointment if:

• You have been worrying a lot, most days, for six months or more
• The worry is affecting your sleep, work, studies or relationships
• You feel tense, restless or irritable much of the time
• You are avoiding things you used to do because of anxiety
• You want to talk about treatment options, or you have tried self-help and it has not been enough
• You are not sure whether what you feel is anxiety or something else — a doctor can help you work it out

Diagnosis

There is no single test for GAD. Your doctor will usually talk with you about how you have been feeling, how long it has been going on, what you worry about, and how much it affects your daily life. They may ask you to fill in a short questionnaire about worry and mood. They will also check whether something physical or another condition could explain your symptoms, and they will ask about caffeine, alcohol, drugs and any medicines you take. Diagnosis is based on your pattern of symptoms over time — feeling anxious most days for months, about many different things, and finding it hard to control.

Tests that may be done

• A conversation about your symptoms, history and daily life — this is the most important part
• A short written questionnaire about anxiety and low mood
• A physical check, such as blood pressure and listening to your heart and chest
• Blood tests — for example to check the thyroid, iron levels or blood sugar — to rule out other causes
• A heart tracing (ECG) if you have palpitations or chest symptoms
• Questions about caffeine, alcohol, recreational drugs and any medicines or supplements you take

What to expect at your appointment

You may feel nervous about the appointment, and it can help to write down your symptoms beforehand — how often they happen, how long they last, and what they stop you doing. Your doctor should listen without judging you. Some people need more than one appointment before the picture is clear. If your symptoms are mild, you may be offered self-help resources and a check-in later. If they are more troubling, you should be offered talking therapy, and sometimes medicine as well. Ask questions if anything is unclear, and ask what the plan is and when to come back.

Treatment

GAD can be treated, and most people improve. The main treatments are talking therapies and, for some people, medicine. The right choice depends on how severe your symptoms are, what you have already tried, and what you prefer. Many people do best with a combination of both. Treatment is usually stepped — starting with self-help and short courses of therapy, and adding more support if needed. Waiting lists can be long in some areas, so it is worth asking what is available locally, including online courses and guided self-help while you wait.

Self-care at home

• Learn slow breathing — breathe in gently through your nose for a count of four, and out for a count of six, for a few minutes when you feel tense
• Try relaxation or muscle-relaxing exercises, or a calming app or audio track
• Set aside a regular 'worry time' of about 15 minutes a day — write down your worries, then park them until the next day
• Write down a worry and ask yourself: can I do something about this? If yes, make a small plan. If no, practise letting it go
• Keep a regular sleep routine — same bedtime and wake time, and no screens just before bed
• Cut back on caffeine, energy drinks and alcohol, and notice how they affect you
• Move your body most days, even a short walk — it genuinely helps lower anxiety
• Stay connected — tell one person you trust how you are feeling rather than keeping it to yourself
• Be kind to yourself. Anxiety is not a character flaw, and progress is usually gradual

Medical treatments

Talking therapies are the main treatment. The most commonly recommended is cognitive behavioural therapy (CBT), which helps you notice unhelpful thought patterns and learn practical ways to respond to worry. Other options include applied relaxation training, guided self-help (with a book or online programme and brief support from a practitioner), and group courses. For some people, a type of antidepressant medicine that is also used for anxiety may be offered — it is usually started at a low dose and taken for several months, and it can take a few weeks to help. Your doctor should explain the benefits, the possible side effects and how to stop safely. Other medicines are sometimes used for a short time to ease physical symptoms. Medicine is not right for everyone, and it is always your choice. Never start or stop a medicine without speaking to your doctor or pharmacist.

When is surgery considered?

Surgery is not a treatment for generalised anxiety disorder. Treatment is based on talking therapies, self-help and sometimes medicine.

Living with this condition

Living with GAD can be tiring, because your mind is working hard even when nothing is happening. It helps to build small, predictable routines: get up at a similar time, eat regular meals, move your body, and plan one pleasant thing each day. Try not to let anxiety shrink your world — avoiding things feels better for a moment but teaches your brain to be more afraid. Instead, take small steps towards the things you have been avoiding, and praise yourself for each one. Some days will be harder than others, and that is normal. Keep a note of what helps, so you can go back to it on a bad day.

Lifestyle tips

• Keep a regular sleep and wake time, and give yourself wind-down time before bed
• Build in short daily movement — walking, swimming, cycling, dancing or anything you enjoy
• Reduce caffeine, energy drinks and alcohol, especially in the evening
• Try mindfulness or relaxation practice for a few minutes each day
• Keep in touch with friends and family, even when you feel like withdrawing
• Limit doom-scrolling and news checking, and set times to check your phone
• Plan things to look forward to, even small ones
• Consider joining a peer support group, in person or online

Diet and exercise

There is no special diet for anxiety, but eating regularly helps keep your energy and mood steady — try not to skip meals, and include plenty of vegetables, fruit, wholegrains and protein. Drink enough water. Caffeine and alcohol are the two things most likely to make anxiety worse, so it is worth cutting down and noticing the difference. Regular physical activity is one of the most reliable ways to lower anxiety: aim for something that raises your heart rate a little most days, and start small if you are not used to it. Even a ten-minute walk counts.

Mental health and emotional wellbeing

GAD often travels with other difficulties, especially low mood and depression. It can also chip away at confidence, make you feel isolated, and be exhausting to explain to other people. None of this means you are failing — it means you are dealing with something real that deserves support. If at any point you have thoughts of harming yourself or ending your life, please reach out immediately: call your local emergency number, or contact a crisis line in your country. You deserve help right away, and you do not have to cope alone.

Prevention

You cannot always prevent GAD, especially if anxiety runs in your family or you have been through difficult experiences. But you can lower the chance of anxiety building up, and reduce how much it affects you. Learning to notice early warning signs — poor sleep, tense shoulders, feeling irritable, avoiding things — and acting on them early helps a lot. Building regular sleep, movement, relaxation and connection into your week gives you a stronger base. If you are going through a stressful time, tell your doctor or ask about support before things pile up.

Screening programmes

There is no national screening programme for generalised anxiety disorder. Doctors sometimes ask brief questions about worry and mood during appointments for other reasons, or when you are going through a difficult time. If you are unsure whether what you feel is anxiety, it is always reasonable to raise it with your doctor.

Complications

If left untreated

• Low mood or depression
• Sleep problems that make everything else harder
• Using alcohol, drugs or overeating to cope
• Physical strain, such as headaches, gut problems and long-term tiredness
• Struggling at work, in study or with money because of poor concentration and avoidance
• Relationships becoming strained, or withdrawing from friends and family
• Losing confidence and becoming more isolated
• Feeling hopeless about the future

Long-term outlook

The outlook is genuinely good. Generalised anxiety disorder is one of the most treatable mental health conditions, and most people who get support notice a real difference. Talking therapy in particular has strong evidence behind it, and many people learn skills they keep for life. Recovery is usually gradual rather than a single switch, and setbacks are a normal part of it — not a sign that you are back at the start. With the right help and a little patience with yourself, life can become calmer and more manageable again.
