Health Anxiety

What it is

Illness anxiety disorder is a persistent and excessive preoccupation with the fear of having, or developing, a serious illness. Unlike somatic symptom disorder, where distressing physical symptoms are the centre, here there are few or no actual physical symptoms, or only mild ones, and yet the person is consumed by the worry that something is gravely wrong. The fear is the illness, in a sense: it is the anxiety itself that causes the suffering and disruption.

This was once called hypochondria, a word now avoided in care because it became an insult, a way of dismissing people as fussing over nothing. That dismissal misses the truth: the fear is genuine, distressing and often disabling, and the person is not choosing it or enjoying the attention. They are trapped in a cycle of anxiety about their health that they cannot reason their way out of, and that cycle responds well to the right help.

What it can feel like

Two patterns are common. Some people are constant checkers: repeatedly examining their body, searching symptoms online, seeking test after test, and asking for reassurance from doctors and family, gaining brief relief that quickly gives way to fresh fear. Others are avoiders: so frightened of bad news that they avoid doctors, tests and anything that might confirm their worst fear, while the anxiety simmers underneath. Either way, the fear is exhausting and intrusive. A normal bodily sensation, a headache, a skipped heartbeat, a lump that is nothing, becomes evidence of catastrophe. Reassurance does not last, because the anxiety always finds a new doubt. Internet searching, in particular, tends to feed the fear rather than calm it.

How common is it

Health anxiety is common, affecting a meaningful proportion of people to some degree, and it is frequently seen in general medical settings. It can begin at any age, often rises at times of stress or after illness or bereavement in oneself or others, and tends to wax and wane over time. It is closely related to other anxiety conditions and to obsessive-compulsive disorder.

What causes it

Health anxiety usually grows from a mix of factors: a general tendency toward anxiety, past experiences of serious illness or death in oneself or the family, having grown up around illness or excessive health concern, a major health scare, and a habit of interpreting normal bodily sensations as dangerous. Times of stress and loss often trigger or worsen it. The modern flood of health information online, much of it alarming, gives the anxiety endless fuel. As with the other conditions in this chapter, the mind-body link is real: anxiety produces genuine physical sensations, which then seem to confirm the feared illness, tightening the loop.

How it is diagnosed

A doctor first ensures that appropriate medical assessment has been done, because people with health anxiety can of course also develop real illnesses, and their concerns deserve proper attention. The diagnosis then rests on recognising the persistent, excessive fear of illness that is out of proportion to any actual medical findings and that dominates the person's life, along with the checking or avoidance behaviours. As elsewhere in this chapter, the skill lies in taking the person seriously while not feeding the cycle with endless unnecessary tests.

How it is treated

Health anxiety responds well to treatment, and the most effective approach is talking therapy, especially cognitive behavioural therapy designed for health anxiety. Rather than chasing the feared illness, this therapy works directly on the anxiety: helping the person understand the cycle, reduce the checking, reassurance-seeking and internet searching that keep it going, respond differently to normal bodily sensations, and tolerate uncertainty about health, which no amount of testing can ever fully remove. A consistent relationship with one trusted doctor, with regular appointments and limits on unnecessary tests, supports the therapy. Where anxiety is severe, an SSRI can help, often the same medicines used for other anxiety conditions. Treating any underlying depression or other anxiety disorder matters too. The realistic message is hopeful: most people can be freed from the grip of health fear and get their lives back.

Illness anxiety in the African context

Health anxiety has a particular shape here. Real and serious health threats are part of life, and the internet and well-meaning warnings amplify fear, so worry about illness is understandable, but in illness anxiety disorder the fear takes over even when checks are reassuring. Some people seek test after test from many clinics, while others avoid doctors entirely out of dread. Both patterns are driven by anxiety rather than disease. Recognising the condition as a treatable anxiety problem, rather than either a real illness or mere attention-seeking, and treating the anxiety itself, is what brings relief and breaks the exhausting cycle of checking and worry.

Helping someone

If someone you love is consumed by fear of being seriously ill, a calm approach helps.

• Take the distress seriously as real anxiety, even when the feared illness is not present.
• Avoid endless reassurance about their health, which calms only briefly and then feeds the next worry.
• Gently encourage them to see one trusted doctor, and to treat the anxiety rather than chase more tests.
• Encourage professional help, since anxiety-focused therapy is effective. Our find a therapist page can help.
• Be patient, and try not to argue them out of the fear, which rarely works.
