Many people who experience health anxiety know, on some level, that their worry is disproportionate to what the evidence suggests. They may have had the tests, received reassurance from a doctor, and been told that everything is fine. The relief tends to be short-lived. Within days, or sometimes hours, the worry is back, attaching itself to a different symptom or revisiting the same one with renewed urgency.
The gap between knowing and feeling is not a sign of irrationality. It is one of the defining features of health anxiety, and understanding why that gap exists is part of what makes the condition treatable.
What is health anxiety?
Health anxiety is a pattern of persistent, intrusive worry about being seriously ill, or about developing serious illness, in the absence of medical evidence that would justify the level of concern. The worry is not simply cautious or health-conscious. It is characterised by a specific relationship with physical symptoms, one in which ordinary bodily sensations, a headache, a twinge, a change in heartbeat, become interpreted as evidence of something significant and potentially threatening.
People with health anxiety often spend considerable time seeking reassurance, through medical consultations, online searches, or asking people around them. The reassurance tends to reduce anxiety briefly before the cycle restarts. Over time, the checking and reassurance-seeking can become as distressing as the underlying fear itself, occupying a disproportionate amount of daily attention and energy.
Why is health anxiety so cyclical?
The difficulty lies in the nature of the reassurance cycle. Each time anxiety about a symptom spikes and reassurance is sought and received, the anxiety reduces. The mind learns that seeking reassurance was what made things better. Next time the anxiety rises, the pull toward checking and reassurance is stronger because that is what worked before. Over time, the threshold for what counts as reassuring gets higher, and the frequency of checking tends to increase.
There is also the fundamental problem that health is genuinely uncertain. No doctor can say with absolute certainty that someone is or will remain healthy. For a person with health anxiety, that uncertainty is not manageable, and each qualified reassurance, ‘there is nothing to suggest anything serious at this stage’, gets heard through a lens that picks up only the qualification rather than the reassurance.
Search engines have made this considerably more difficult. Symptoms that would previously have prompted a call to a GP now prompt a search that returns a list of conditions ranging from the benign to the serious, with no way to calibrate which is relevant. The phenomenon has its own clinical term, cyberchondria, and research indicates that online symptom-searching tends to increase health anxiety rather than resolve it.
Who tends to experience health anxiety?
Health anxiety can develop at any age and is not limited to people with a prior history of anxiety. It frequently emerges or intensifies following a significant health event, either personal or experienced by someone close, a period of stress, or a bereavement. For some people it is a longstanding pattern, present for years before it is named or recognised. For others it arrives more suddenly and is more clearly connected to a specific trigger.
Research involving more than 43,000 patients attending UK medical clinics found that around 1 in 5 had significant health anxiety, a figure that was frequently neither identified nor addressed in the general medical setting. The gap between prevalence and recognition is significant, partly because health anxiety often presents through physical complaints rather than as an explicitly psychological concern, and partly because the overlap with health monitoring makes it harder to identify.
How does health anxiety differ from wise concern?
This is a question many people with health anxiety ask themselves, and the honest answer is that the line is not always clear. Concern about health is wise and appropriate. Getting a symptom checked is a sensible thing to do. The distinction tends to lie in what happens after reassurance: whether it is possible to accept it and return to ordinary functioning, or whether the anxiety quickly restores itself and drives further checking.
The impact on daily life is another marker. When worry about health is occupying significant amounts of time and attention, affecting sleep, relationships, or work, and when the pattern has been present for weeks or months rather than days, the concern has moved into territory that warrants support rather than further medical investigation.
What tends to help?
The psychological treatment with the strongest evidence base for health anxiety is Cognitive Behavioural Therapy (CBT). Specifically, CBT approaches for health anxiety focus on the relationship between physical symptoms, interpretations, and the reassurance and avoidance behaviours that maintain the cycle. The goal is not to convince someone they are well, but to develop a different relationship with uncertainty and with the physical sensations themselves.
Where health anxiety is part of a longer-standing pattern of anxiety or where it connects to broader beliefs about safety, control, or the body, other therapeutic approaches may be relevant alongside or instead of CBT. Schema Therapy can be particularly useful where the roots of the anxiety are long-standing, working at the level of the underlying beliefs that drive the checking cycle rather than the cycle itself.
At London Bridge Therapy, the initial assessment is designed to establish which approach is most appropriate for what you are bringing, and the team of Clinical Psychologists and Counselling Psychologists and Expert Integrative Psychotherapists includes therapists with experience in anxiety presentations including health anxiety.
