Health anxiety involves persistent, excessive worry about having or developing a serious illness — despite medical reassurance that nothing is wrong, or despite the reassurance only providing brief relief. Also known as illness anxiety or hypochondria, it is more common than many people realise and can consume enormous amounts of time and energy. CBT is highly effective for health anxiety.
Health anxiety is characterised by preoccupation with the fear of having or developing a serious illness. The anxiety is disproportionate to any symptoms present — or may occur in the absence of any physical symptoms at all. Crucially, medical reassurance provides only temporary relief before doubt returns and the reassurance-seeking cycle begins again.
Health anxiety exists on a spectrum. Mild health anxiety involves periodic excessive worry about health. Severe health anxiety can involve hours each day spent checking the body, researching symptoms online, seeking medical appointments, and being unable to concentrate on anything else.
The DSM-5 separates health anxiety into illness anxiety disorder (anxiety about illness without significant physical symptoms) and somatic symptom disorder (anxiety about real physical symptoms that is disproportionate to their severity). Both respond to similar CBT-based approaches.
Signs of health anxiety include:
CBT is the most evidenced treatment for health anxiety and is recommended by NICE. The CBT approach specifically addresses the maintaining factors — including attention to bodily sensations, reassurance-seeking, avoidance and safety behaviours — rather than the content of individual health fears.
Key elements of treatment include:
It is important that reducing reassurance-seeking is agreed with medical practitioners as part of treatment — some people benefit from a planned reduction in GP appointments as part of the therapeutic work.
Health anxiety is often a source of significant shame — the person knows intellectually that their fears are excessive, which makes it hard to disclose. Please know that health anxiety is a recognised and very common condition, and seeking help is entirely appropriate.
Raising the issue with your GP is a good starting point — they can refer to IAPT and can also help plan a reduction in reassurance-seeking from medical services as part of treatment. Many people find that starting CBT is the most effective route to meaningful change.
We don't currently have any therapies mapped to this condition.
Yes — health anxiety is a recognised mental health condition that causes genuine distress and significant impairment. The fact that the underlying fears are excessive does not make the suffering less real. It responds well to CBT, and seeking help is entirely appropriate.
Reassurance provides brief relief but maintains health anxiety in the long term by reinforcing the belief that reassurance is needed to manage the anxiety. Each reassurance-seeking episode is followed by a return of doubt, requiring further reassurance. Breaking the reassurance cycle is a central part of CBT for health anxiety.
Yes — symptom searching consistently amplifies health anxiety. Search algorithms surface worst-case diagnoses, and the act of searching reinforces attentional focus on bodily symptoms. Reducing internet symptom searching is an important early step in treatment.
Yes — anxiety produces real physical sensations including heart palpitations, chest tightness, dizziness, nausea and muscle tension. These genuine symptoms can then become the focus of further health anxiety, creating a self-reinforcing cycle. A therapist can help you understand and break this pattern.
The CBT approach for health anxiety has specific differences from standard anxiety treatment. It focuses heavily on reducing reassurance-seeking (including from doctors), reducing body checking, and shifting attentional focus away from the body. General anxiety CBT that focuses on thought challenging alone is less effective for health anxiety than approaches that target these specific maintaining behaviours.
