What is Health Anxiety?
Health anxiety, sometimes referred to by its clinical name, Illness Anxiety Disorder, is a condition characterised by obsessive and irrational worry about having a serious medical condition. While it is natural to feel concerned about our health from time to time, those living with health anxiety find that these worries persist even when there is no medical evidence of an issue or when a doctor provides reassurance.
In the UK, the term 'hypochondriasis' was previously used, but healthcare professionals now prefer 'health anxiety' or 'illness anxiety disorder' as they more accurately describe the psychological distress involved. It is not simply 'imagining symptoms'; the physical sensations felt by the individual are often very real, but they are misinterpreted as signs of a life-threatening illness. This cycle can significantly interfere with a person's quality of life, work, and relationships.
Common Symptoms and Behaviours
Health anxiety manifests through both physical sensations and behavioural patterns. Recognising these is the first step toward management. Common signs include:
- Body Checking: Frequently checking the body for lumps, rashes, or changes in heart rate and skin texture.
- Reassurance Seeking: Repeatedly asking family, friends, or doctors for reassurance that they are not ill.
- Cyberchondria: Obsessively searching health symptoms online, which often leads to imagining the worst-case scenario.
- Avoidance: Avoiding medical appointments or health-related television programmes out of fear of a diagnosis.
- Hyper-vigilance: Being overly aware of normal bodily functions, such as a heartbeat or 'stomach gurgling', and interpreting them as signs of catastrophe.
Physical symptoms of the anxiety itself—such as a racing heart, chest tightness, or sweating—can also be mistaken for signs of physical illness, creating a distressing feedback loop.
What Causes Health Anxiety?
There is rarely a single cause for health anxiety. It often develops due to a combination of internal and external factors. Some people may have a natural tendency toward anxiety or a 'perfectionist' personality type. Previous experiences with illness, either personally or through a family member, can also trigger a heightened fear of medical problems.
The modern digital landscape plays a significant role in the UK. With immediate access to medical databases, 'self-diagnosis' has become common. However, without clinical training, individuals often overlook more likely, benign causes for their symptoms, focusing instead on rare or terminal conditions. Stressful life events, such as bereavement or job loss, can also lower a person's resilience, making them more susceptible to health-related intrusive thoughts.
Self-Help Strategies for Managing Anxiety
If you feel your worries about your health are becoming unmanageable, several evidence-based techniques can help break the cycle of anxiety:
- Keep a Worry Diary: Record how often you check your body or search for symptoms online. Noticing these patterns can help you consciously reduce them.
- Challenge Intrusive Thoughts: When you feel a sensation, ask yourself: 'Is there a more likely, less serious explanation for this?' or 'Have I felt this way before when I was stressed?'
- Gradual Reduction: If you check your pulse ten times a day, try to reduce it to five, then two, then once.
- Stay Active: Regular exercise is proven to reduce overall anxiety levels and can help you reconnect with your body in a positive way.
It is important to remember that these strategies take time and consistency. Healing is not about never having a health-related thought again; it is about learning not to let those thoughts control your actions.
UK Treatment Options and Support
In the UK, the National Institute for Health and Care Excellence (NICE) recommends specific treatments for health anxiety. The most common and effective approach is Cognitive Behavioural Therapy (CBT).
Cognitive Behavioural Therapy (CBT): This therapy helps you identify the triggers for your health anxiety and teaches you how to change the thought patterns and behaviours that keep the anxiety going. Exposure and Response Prevention (ERP) may also be used to help individuals face their fears of illness without resorting to checking or reassurance-seeking.
Medication: In some cases, a GP may prescribe selective serotonin reuptake inhibitors (SSRIs). While primarily used for depression, these are also effective for various anxiety disorders. They are often used in conjunction with therapy rather than as a standalone cure.
You can access support through your local NHS GP, or via NHS Talking Therapies (formerly IAPT), which allows for self-referral in many parts of England.
When to See an Online GP
Knowing when to seek professional help is vital. If your concern about your health is causing you significant distress, affecting your ability to work, or impacting your relationships, it is time to speak to a clinician. An online GP consultation can provide a calm, confidential environment to discuss your symptoms and your mental well-being.
The benefit of speaking with a GP is their ability to perform a clinical assessment. If they determine your physical symptoms have an underlying mental health cause, they can guide you toward the correct psychological support, such as a referral for CBT or a Fit Note (sick note) if you need time away from work to focus on recovery. Alternatively, if there is a physical concern that requires investigation, they can provide the necessary advice or referrals, helping to end the cycle of uncertainty.
