Health anxiety can make ordinary physical sensations feel frightening. A headache may immediately raise concerns about a serious illness. A small change in your body may lead to hours of searching online, checking symptoms, or asking others for reassurance.
Everyone worries about their health from time to time. However, when health-related worry becomes persistent, difficult to control, and starts interfering with everyday life, it may be a sign of health anxiety, sometimes referred to clinically as illness anxiety disorder.
In this CareCraft Meds Now guide, we explain what health anxiety feels like, common symptoms, possible causes, the connection between anxiety and physical sensations, and ways to manage it.
What Is Health Anxiety?
Health anxiety is excessive worry about being seriously ill or becoming seriously ill. A person may interpret normal body sensations or minor symptoms as evidence of a dangerous disease.
Importantly, health anxiety can occur even when medical examinations have not found a serious underlying condition. The worry itself can become the main source of distress.
The older term hypochondria or hypochondriasis is still commonly used online, but modern clinical terminology generally uses illness anxiety disorder in appropriate cases.
If you are also experiencing persistent worrying, racing thoughts or physical symptoms of anxiety, read our related guide on [Anxiety Symptoms in Adults].
What Does Health Anxiety Feel Like?
Health anxiety can feel very real and overwhelming. You may find yourself repeatedly asking:
- “What if this symptom means something serious?”
- “What if my doctor missed something?”
- “Why does my body feel different today?”
- “Could this headache be something dangerous?”
- “What if my test result was wrong?”
- “Why can’t I stop thinking about my health?”
- “Should I search this symptom online?”
One of the most difficult parts of health anxiety is uncertainty. Even after receiving reassurance from a doctor or getting normal test results, the worry may return.
The NHS lists excessive health worry, repeated body checking, seeking reassurance and repeatedly searching health information online among common signs of health anxiety.
Common Health Anxiety Symptoms
Health anxiety can affect your thoughts, behaviour and physical sensations.
1. Constantly worrying about your health
You may spend a significant amount of your day thinking about illnesses and wondering whether something is wrong with your body.
2. Repeatedly checking your body
Some people repeatedly check their pulse, skin, lymph nodes, breathing, heart rate or other parts of their body for signs of illness.
3. Searching symptoms online
Searching for symptoms can temporarily feel reassuring, but repeatedly looking for possible diseases online may increase anxiety and make you focus even more closely on normal bodily sensations.
4. Frequently seeking reassurance
You might repeatedly ask family members, friends or healthcare professionals whether you are seriously ill.
5. Worrying that doctors missed something
Even after receiving reassuring medical results, you may continue thinking that something was overlooked.
6. Avoiding activities
Health anxiety can sometimes cause people to avoid exercise, travelling, social activities or other situations because they fear becoming ill.
7. Difficulty concentrating
Persistent health worries can make it difficult to concentrate on work, study, relationships or everyday tasks.
Can Anxiety Cause Physical Symptoms?
Yes. Anxiety can produce genuine physical sensations.
When your body responds to anxiety, stress hormones can contribute to symptoms such as a faster heartbeat, sweating, dizziness, headaches, nausea, stomach problems, shaking and breathlessness.
This can create a difficult cycle:
Physical sensation → worrying about the sensation → increased anxiety → stronger physical sensation → more worrying
For example, anxiety may cause your heart to beat faster. You notice the change and become frightened that it indicates a heart problem. That fear increases your anxiety, which can make your heartbeat feel even more noticeable.
This does not mean that every physical symptom is caused by anxiety. New, persistent or concerning symptoms should be discussed with an appropriate healthcare professional rather than automatically being attributed to anxiety.
Why Does Health Anxiety Happen?
There is no single cause of health anxiety. Several factors may contribute.
Possible factors include:
- Previous experiences with serious illness
- Having a close relative with a serious illness
- Major periods of stress
- Difficulty tolerating uncertainty
- A tendency to worry excessively
- Previous frightening medical experiences
- Excessive health-related internet searching
Health anxiety may also become worse during stressful periods.

Why Does Googling Symptoms Make Health Anxiety Worse?
Searching online for health information is not automatically harmful. Reliable medical information can be useful.
The problem can arise when searching becomes repetitive or compulsive.
You might search:
“headache causes”
Then see a list containing dozens of possible conditions. You may begin comparing your symptoms with the most serious possibilities, search again, and become increasingly worried.
This can create a reassurance cycle:
Worry → Google symptoms → temporary reassurance → notice another symptom → Google again → increased anxiety
The NHS specifically recommends reducing repeated checking and excessive searching for health information as part of managing health anxiety.
Health Anxiety vs General Anxiety
Health anxiety focuses particularly on illness, symptoms and fears about physical health.
Generalised anxiety, on the other hand, can involve excessive worry across several areas of life, such as finances, work, relationships, family and health.
A person can experience both health anxiety and another anxiety disorder, which is why professional assessment can be useful when anxiety becomes difficult to manage.
How to Stop Health Anxiety From Taking Over Your Life
There is no instant solution, but several strategies can help reduce the cycle of health-related worry.
1. Reduce repeated body checking
Notice how frequently you check your body for signs of illness. Gradually reducing this behaviour may help break the reassurance cycle.
2. Limit symptom searching
Consider setting boundaries around online health searches. If you notice yourself repeatedly searching the same symptom, pause and ask whether the search is actually helping.
3. Challenge catastrophic thoughts
Instead of immediately assuming the worst possible explanation, consider alternative explanations.
For example:
Anxious thought:
“This headache must mean something serious.”
Balanced thought:
“There are many possible causes of headaches, and anxiety and stress can also produce physical symptoms. If I’m concerned, I can discuss it with a healthcare professional.”
The goal isn’t to convince yourself that nothing could ever be wrong. It is to avoid automatically assuming the worst.
4. Return to normal activities
Avoiding everyday activities can reinforce anxiety. Gradually returning to activities you have stopped because of health worries can help rebuild confidence. The NHS recommends gradually getting back to normal activities such as exercise and socialising when health anxiety has led to avoidance.
5. Practise relaxation techniques
Breathing exercises, physical activity and other stress-management techniques may help reduce anxiety.
6. Keep a health-anxiety diary
Write down:
- What triggered the worry
- What you thought might be wrong
- What you did in response
- How long the anxiety lasted
- Whether checking or reassurance actually helped
This can help you identify patterns.
What Is the Treatment for Health Anxiety?
If health anxiety is significantly affecting your life, professional treatment can help.
Cognitive behavioural therapy (CBT) is commonly used to treat health anxiety. CBT can help you recognise unhelpful interpretations of physical sensations and change behaviours such as excessive checking and reassurance seeking.
Depending on the individual’s circumstances, a healthcare professional may also consider medication for anxiety or related conditions. Medication decisions should be made with a qualified healthcare professional because the appropriate treatment depends on the person’s symptoms, medical history and other factors.
When Should You See a Doctor About Health Anxiety?
Consider speaking with a GP or other qualified healthcare professional if:
- Health worries are interfering with your normal life
- You repeatedly check your body
- You frequently search symptoms online
- You repeatedly seek reassurance
- You avoid activities because you fear becoming ill
- Anxiety is affecting your work, relationships or sleep
- Self-help strategies are not helping
The NHS recommends speaking with a GP when health worries prevent you from living normally or when self-help isn’t working.
It is also important not to assume that a new physical symptom is caused by anxiety without appropriate medical assessment.
Frequently Asked Questions About Health Anxiety
Is health anxiety a real condition?
Yes. Health anxiety can cause substantial distress and interfere with everyday life. When appropriate clinical criteria are met, it may be diagnosed as illness anxiety disorder.
Can health anxiety cause physical symptoms?
Yes. Anxiety can produce physical symptoms including increased heart rate, dizziness, headaches, nausea, sweating and breathlessness.
Why do I keep thinking I am sick?
Health anxiety can cause you to interpret normal sensations or minor symptoms as evidence of serious illness. Repeated checking, reassurance seeking and internet searching can then maintain the cycle.
Can health anxiety go away?
Health anxiety can improve with appropriate support and treatment. CBT and other forms of psychotherapy can be effective, while some people may also benefit from medication prescribed by a healthcare professional.
Is health anxiety the same as hypochondria?
“Health anxiety” and “hypochondria” are commonly used terms for excessive fear about illness. In modern clinical terminology, the relevant diagnosis may be called illness anxiety disorder.
How do I stop Googling my symptoms?
Start by recognising when searching has become a reassurance behaviour. Set limits on symptom searches, redirect your attention to another activity and discuss persistent concerns with a healthcare professional rather than repeatedly searching for increasingly serious explanations.
Final Thoughts
Health anxiety can create a powerful cycle of worrying, checking, searching and seeking reassurance. The physical sensations produced by anxiety can then make the fear feel even more convincing.
The good news is that health anxiety is treatable. Learning to recognise the cycle, reducing repeated checking and reassurance seeking, returning to normal activities and seeking professional support when necessary can make a meaningful difference.
