Health Anxiety

Overview

Health anxiety means worrying a lot that you are ill, or that you are going to become ill, even when there is little or no evidence that something is wrong. Everyone worries about their health now and then. With health anxiety, the worry becomes a big part of daily life. You might keep checking your body for signs of illness, search the internet for symptoms, or ask other people again and again for reassurance. Ordinary feelings — like a fast heartbeat, a headache, a rumble in your stomach, or a small ache — can feel scary and get a lot of attention. The problem is not that you are 'making it up'. The body feelings are real. The trouble is that the alarm system in your brain has become over-sensitive, so normal sensations get treated as danger signals.

Yes. Health anxiety is common. Studies suggest it affects roughly 1 in 20 people at some point in their lives, and many more people have shorter periods of intense health worry. It is one of the reasons people visit their doctor, and doctors are trained to recognise it.

It can affect anyone at any age, but it most often starts in early adulthood. It is seen in people of all backgrounds. It may be more likely in people who have had a serious illness themselves, who care for someone who is ill, who lost someone to illness, who work in healthcare, or who grew up with a parent who worried a lot about health. It affects children too, often as worry about a parent's health.

Symptoms

Common symptoms

• Constantly worrying that you are seriously ill, or that you will become seriously ill
• Checking your body over and over — feeling for lumps, looking in the mirror, taking your pulse or blood pressure
• Searching the internet about symptoms for hours, or reading the same information repeatedly
• Asking family, friends or your doctor for reassurance again and again, but the relief does not last
• Noticing normal body sensations (heartbeat, breathing, digestion, aches) and treating them as warning signs
• Feeling that tests or doctors have 'missed something' even after being told you are well
• Avoiding doctors, hospitals or health information altogether because it feels too frightening
• Trouble sleeping, feeling tense or restless, difficulty concentrating
• Panic feelings — a racing heart, sweating, shaking, shortness of breath or a churning stomach

Symptoms in children

• Frequent stomach aches or headaches, often around school or bedtime
• Repeated questions about whether a parent or carer is safe and well
• Wanting to stay close to a parent, or being reluctant to go to school or sleepovers
• Checking their own body or asking about small marks, aches and bruises
• Worry that seems out of proportion to what is happening, and hard to settle

Symptoms in older adults

• Intense worry about normal signs of ageing, such as memory slips, tiredness or joint stiffness
• Worry that a real long-term condition is getting worse, even when check-ups are stable
• Lots of appointments or calls to health services, sometimes after a bereavement or a period of loneliness
• Fear of falling or of losing independence, which can lead to avoiding activity
• Worry that can look like irritability, poor sleep or low mood rather than obvious fear

Causes

Main causes

• An over-sensitive 'danger alarm' in the brain, where normal body signals are read as threats
• A tendency to worry, or a personality style that finds uncertainty very hard to tolerate
• Past experiences — a serious illness, a frightening health scare, or watching someone you love be ill
• Learning from family — growing up with someone who checked their body or worried about health a lot
• Stressful life events such as bereavement, job loss, exams or relationship problems
• Health information overload, where symptom lists online make rare illnesses feel likely

Risk factors

• Having another anxiety problem, depression or obsessive-compulsive disorder (OCD — a condition with unwanted repeated thoughts and urges to repeat actions)
• A family history of anxiety or health worry
• A personal history of a serious or long-term illness
• Caring for someone who is unwell, or recent bereavement
• Working in healthcare or having easy access to medical information
• Being in a period of high stress or big life change

When to see a doctor

See a doctor urgently if:

• You have a new physical symptom that is severe, getting worse, or worrying you a lot — it is always okay to be checked
• You feel you cannot keep yourself safe, or you have thoughts of harming yourself
• Anxiety is stopping you from eating, sleeping, working or caring for yourself or others

Book a routine appointment if:

• Worry about your health is using up a lot of your time or energy
• You keep checking your body or searching online, and it does not help for long
• Reassurance from others only calms you for a short time
• Fear about illness is affecting your sleep, mood, work or relationships
• You are avoiding doctors, tests or activities because of fear

Diagnosis

There is no single test for health anxiety. Your doctor will usually start by listening to your story and asking about your symptoms, how long they have lasted, how often you check or seek reassurance, and how much this affects your daily life. They will also ask about your mood, sleep, stress and any past health problems. Because real physical conditions can exist alongside health anxiety, your doctor may do a basic physical check or order a test or two if something specific needs ruling out. Once they have enough information, they can explain what is likely going on and offer treatment.

Tests that may be done

• A conversation and questions about your symptoms, thoughts and daily habits — the most important part of the assessment
• A short written questionnaire about anxiety, worry or mood
• A physical examination if there is a particular symptom to check
• Blood tests or other simple tests only if your doctor thinks they are needed — not as a routine for health anxiety

What to expect at your appointment

You may feel nervous about raising the subject, but doctors are used to these conversations and will not judge you. It can help to write down beforehand: what you worry about, how often you check or search, what helps and what does not, and what you would like from the appointment. If testing is done, remember that a clear result is useful information — but it will not simply switch the worry off. Treating the anxiety itself is what makes the lasting difference. If you feel a test was rushed or you were not heard, it is fine to ask for a review.

Treatment

Health anxiety responds well to treatment, and most people get noticeably better. The main approaches are talking therapy, learning practical ways to manage worry, and sometimes medicine. Your doctor can help you choose what fits you best, and you can change your mind along the way. Treatment usually happens while you continue your normal life, not in hospital.

Self-care at home

• Agree a checking plan with your doctor and stick to it — this reduces the urge to keep asking
• Set a daily limit on body checking, and gradually reduce it
• Try a 'worry window': set aside 15 minutes a day to write worries down, then close the notebook and move on
• Reduce internet symptom searching, or ask someone to help you block health sites for a while
• Write down what actually happened after a worry — for example, 'the headache eased after an hour' — to build a more balanced picture
• Practise slow breathing: breathe in for about four seconds, out for about six, for a few minutes when you feel tense
• Keep regular sleep, meals, movement and time with people you enjoy
• Tell one or two trusted people what you are working on, so they can support you without constant reassurance

Medical treatments

The best-studied treatment is cognitive behavioural therapy (CBT), a talking therapy that helps you notice unhelpful thought patterns and practise responding differently — for example, tolerating uncertainty instead of checking. CBT for health anxiety is often short, structured and practical, and can be done one-to-one, in a group, or through guided self-help programmes, in person or online. Other talking therapies and counselling can also help, especially if low mood or past experiences are part of the picture. If anxiety is severe or talking therapy alone is not enough, your doctor may discuss antidepressant medicine. These are prescribed and reviewed by a clinician, usually taken for several months, and started at a low dose. Your doctor will explain benefits, side effects and how to stop safely. No medicine suits everyone, so bring your questions to the appointment.

When is surgery considered?

Surgery is not a treatment for health anxiety. If you have a separate physical condition that needs an operation, this will be discussed with you in the usual way. Some people with health anxiety find it helpful to ask for extra time to talk through any planned procedure.

Living with this condition

Recovery is not a straight line. There will be good weeks and harder ones, and that is normal. The aim is not to never notice your body — that is impossible — but to notice without alarm and get back to your life. Practise responding to a worry with 'this is my alarm system being over-sensitive, not a diagnosis', then carry on with what you were doing. Keeping a simple diary of worries, what you did instead of checking, and how it turned out helps you see progress over weeks.

Lifestyle tips

• Keep a regular routine with set times for waking, meals and bedtime
• Build in daily movement you enjoy, even a short walk
• Limit caffeine, energy drinks and alcohol, which can mimic or worsen anxiety feelings
• Make time for hobbies and people, so life is not all about health
• Try relaxation, yoga, mindfulness or gentle exercise to lower overall tension
• Take breaks from news and social media if health stories set off worry

Diet and exercise

There is no special diet that cures health anxiety, but steady habits help. Eat regular meals so hunger and low blood sugar do not cause shaky, racing feelings that get mistaken for illness. Go easy on caffeine, which can cause a fast heartbeat and jitters. Alcohol can feel calming at first but often makes anxiety worse the next day. Aim for movement most days — walking, cycling, swimming, dancing, anything you like — because regular activity lowers stress and improves sleep and mood.

Mental health and emotional wellbeing

Health anxiety and low mood often go together. Constant fear is exhausting and can lead to feeling hopeless, withdrawn or ashamed. These feelings are common and treatable, not a sign of failure. If your mood is low for more than a couple of weeks, or you have thoughts of harming yourself, tell your doctor or contact a local crisis service straight away. You deserve support, and help is available.

Prevention

You cannot always prevent health anxiety, but you can lower the risk and stop it getting worse. Learning to handle uncertainty, keeping worry in perspective, staying active, sleeping well and limiting symptom searching all help. If you have had health anxiety before, knowing your early warning signs — extra checking, more Googling, repeated reassurance seeking — lets you get help sooner. Parents and carers can help children by answering health questions calmly and simply, and by not over-checking in front of them.

Vaccines

There is no vaccine for health anxiety. Staying up to date with the routine vaccinations recommended for your age and health is still sensible, as it protects you from real illnesses — but it does not treat anxiety.

Screening programmes

There is no national screening test for health anxiety. Some doctors ask a couple of simple questions about worry during routine appointments, which can help spot it early. If you know you are prone to health worry, it is worth mentioning this when you book an appointment so your doctor can support you in the right way.

Complications

If left untreated

• Ongoing distress, exhaustion and poor sleep
• Low mood or depression, and sometimes panic attacks
• Unnecessary tests, appointments and sometimes procedures, which carry their own small risks
• Strain on relationships and work, and sometimes financial cost
• Avoiding doctors completely, so real problems are missed
• Reduced enjoyment of life, because so much energy goes into checking and worrying

Long-term outlook

The outlook is good. Health anxiety is a well-understood problem and most people improve a great deal with the right support, especially CBT. Many people learn to notice a worry, let it pass and get back to their lives. Progress often comes in small steps rather than all at once, so be patient and kind with yourself. If the first thing you try does not help, tell your doctor — there are other options.
