A headache, unusual pain or change in your body can naturally make you wonder whether something is wrong.

For some people, however, concerns about health become difficult to control. You may repeatedly check your body, search symptoms online or seek reassurance, only to find that the worry quickly returns.

This can happen with health anxiety, but experiencing anxiety does not mean physical symptoms should automatically be dismissed.

The challenge is that anxiety can produce genuine physical sensations, while physical health conditions can also cause symptoms that deserve assessment. Knowing when to see a GP can help you get appropriate medical advice without becoming trapped in a cycle of worry and reassurance.

Key takeaways

Health anxiety involves persistent worry about having or developing an illness.
Anxiety can cause genuine physical symptoms.
Having health anxiety does not mean every physical symptom is caused by anxiety.
New, persistent, worsening or concerning symptoms may need medical assessment.
Support is available when anxiety about your health begins affecting everyday life.

What is health anxiety?

Health anxiety involves excessive worry about being seriously ill or developing a medical condition.

You might become highly focused on normal bodily sensations or interpret minor symptoms as evidence that something is seriously wrong.

For example, a headache may lead to fears about a neurological condition, or a change in heart rate may trigger concerns about heart disease.

It is normal to worry about your health occasionally. Health anxiety becomes more problematic when the worry is persistent, difficult to control and begins affecting your daily life.

What are common health anxiety symptoms?

Health anxiety can affect both thoughts and behaviour.

Possible health anxiety symptoms include:

Frequently checking your body for changes
Worrying that minor symptoms indicate serious illness
Regularly searching symptoms online
Seeking repeated reassurance
Worrying that medical tests have missed something
Avoiding medical information because it increases anxiety
Struggling to concentrate because of health concerns
Frequently thinking about illness or disease

Some people repeatedly seek medical reassurance, while others avoid appointments because they are frightened about what might be discovered.

Both patterns can interfere with getting appropriate healthcare.

Can anxiety cause physical symptoms?

Yes. Anxiety can cause genuine physical symptoms.

When you feel anxious, your body activates its stress response. This can lead to physical sensations including:

A faster heartbeat
Sweating
Trembling
Muscle tension
Dizziness
Feeling short of breath
Nausea or digestive changes
Headaches
Tingling sensations

These symptoms are real, even when anxiety is contributing to them.

Physical sensations can then create further worry, which may increase anxiety and make the sensations feel more noticeable.

Health anxiety vs real symptoms

It can be difficult to separate health anxiety from symptoms caused by a physical health condition.

There is no simple rule that allows you to determine the cause at home.

Anxiety can produce physical symptoms, but having anxiety does not prevent someone from developing an unrelated medical condition.

Rather than assuming that a symptom is either "just anxiety" or evidence of serious illness, it is usually more useful to consider its duration, severity, pattern and whether it is changing.

A clinician can assess your symptoms alongside your medical history and decide whether further investigation is appropriate.

Why checking symptoms can make health anxiety worse

When you are worried about your health, checking can provide temporary reassurance.

You might examine your skin, monitor your pulse, search online or ask someone whether a symptom looks normal.

The problem is that reassurance often does not last.

A new sensation or piece of information can restart the worry, leading to another round of checking.

Constantly monitoring your body can also make normal sensations more noticeable. This may reinforce the belief that something is wrong, even after appropriate medical reassurance.

Reducing repeated checking can therefore be an important part of managing health anxiety.

Why searching symptoms online can increase worry

Online health information can be useful, but it can also be difficult to interpret without clinical context.

Many symptoms have numerous possible causes.

For example, fatigue, headaches and digestive changes are common symptoms that can occur for many different reasons.

Searching repeatedly may expose you to serious but unlikely explanations without helping you understand which causes are actually relevant to your circumstances.

If you are worried about persistent or concerning symptoms, speaking to a healthcare professional is generally more useful than repeatedly searching for a diagnosis yourself.

When should you see a GP?

You do not need to decide with certainty whether anxiety or illness is responsible before seeking medical advice.

Consider speaking to a GP if:

You have a new symptom that concerns you
A symptom persists or keeps returning
Existing symptoms are getting worse
Symptoms are affecting your everyday activities
You have unexplained changes in your health
You are worried despite trying to manage the symptoms yourself
Health-related anxiety is significantly affecting your quality of life

A GP can assess the wider picture rather than focusing on one symptom in isolation.

Ready Health offers private GP appointments for general symptoms and mental health concerns, with face-to-face, telephone and virtual consultation options.

What happens during a GP appointment?

A GP will usually begin by asking about your symptoms, when they started and how they have changed.

They may also discuss:

Your medical history
Current medications
Family medical history where relevant
Lifestyle factors
Other symptoms
Your mental wellbeing

A physical examination may be appropriate depending on the concern.

If further investigation is clinically indicated, Ready Health's GP service can provide or arrange next steps such as investigation requests, referrals or follow-up.

The purpose is to reach an appropriate clinical plan rather than automatically assuming that symptoms are caused by either anxiety or physical illness.

What if medical tests are normal but you are still worried?

Normal results can be reassuring, but for someone experiencing health anxiety, the relief may be short-lived.

You may begin wondering whether the test was accurate, whether something was missed or whether another investigation is needed.

If a clinician has appropriately assessed your symptoms and explained that further testing is not required, repeatedly seeking additional tests may reinforce the cycle of health anxiety rather than resolving it.

At this point, discussing the anxiety itself can be important.

This does not mean your symptoms were imaginary. It means the ongoing fear surrounding your health may also need attention.

When health anxiety starts affecting everyday life

Health anxiety can become exhausting.

Persistent worry may affect:

Sleep
Work
Relationships
Concentration
Social activities
Exercise
Willingness to travel
Everyday enjoyment

Some people organise significant parts of their lives around avoiding illness or monitoring symptoms.

If concerns about your health are taking up a large amount of your time or preventing you from doing things you would normally enjoy, seeking support can be worthwhile even when there is no identified physical illness.

What support is available for health anxiety?

The right support depends on your individual circumstances.

Talking therapies can help people explore patterns of worry and develop practical strategies for managing anxiety.

Ready Health provides one-to-one counselling for anxiety, stress and related concerns at its Standish clinic. Patients can self-refer for counselling without requiring a GP referral.

Ready Health also provides private GP appointments, including dedicated 30-minute appointments for stress, anxiety or mood concerns.

This means support can focus on both the symptoms that are worrying you and the anxiety surrounding them.

Is health anxiety the same as illness anxiety disorder?

The terms are related, but they are not always used in exactly the same way.

Illness anxiety disorder is a recognised mental health diagnosis involving a persistent preoccupation with having or developing a serious illness despite absent or relatively mild physical symptoms.

Health anxiety is a broader term commonly used to describe excessive worry about health.

You should not attempt to diagnose illness anxiety disorder yourself based on online information.

A qualified healthcare professional can assess your symptoms and determine what type of support may be appropriate.

How can you manage worries about symptoms?

If you have already received appropriate medical advice, there are practical steps that may help reduce repeated health-related worry.

These can include:

Limiting repeated symptom searches online
Reducing unnecessary body checking
Noticing when you repeatedly seek reassurance
Keeping normal routines where possible
Using relaxation or stress-management techniques
Talking openly about anxiety with a healthcare professional
Considering counselling or another appropriate talking therapy

The aim is not to ignore genuine symptoms.

Instead, it is to develop a healthier balance between responding appropriately to changes in your health and repeatedly checking for signs of illness.

What if you are worried about symptoms right now?

If you are unsure about a symptom, seeking appropriate medical advice is reasonable.

You do not need to wait until you know whether the cause is physical or psychological.

A GP can assess your symptoms, consider your medical history and determine whether examination, investigation, treatment or reassurance is appropriate.

Ready Health offers private GP appointments for non-emergency health concerns, including same-day appointments where available.

If symptoms are severe or you believe you are experiencing a medical emergency, you should use the appropriate urgent or emergency healthcare service rather than waiting for a routine private GP appointment.

Final points

Health anxiety can make it difficult to know when a physical symptom needs medical attention and when anxiety may be amplifying your concern.

Anxiety can produce genuine physical symptoms, but physical symptoms should not automatically be attributed to anxiety without appropriate consideration.

New, persistent, worsening or concerning symptoms may warrant a GP assessment.

If medical reassurance does not reduce your worry, or concerns about illness are affecting your daily life, addressing the anxiety itself can be equally important.

Ready Health provides private GP appointments for physical and mental health concerns, alongside one-to-one counselling for anxiety and stress, allowing you to seek appropriate support based on your individual needs.
