Health anxiety: when checking your body makes it worse

Some of the most anxious people I have seen in clinic are the ones whose test results keep coming back normal. They arrive with a lump they have pressed a dozen times that morning, or a tingling they have been monitoring for a week, and the reassurance I give them works beautifully, for about two days. Then a new sensation turns up and the whole search starts again.

That pattern has a name: health anxiety. The NHS describes it as worrying so much that you are ill, or going to get ill, that the worry starts to take over your life. In one large English study, when researchers screened nearly 29,000 hospital outpatients, about 1 in 5 scored high for health anxiety.

The short version

• Health anxiety is worry about illness that takes over daily life. Checking your body, googling symptoms and asking for reassurance are its main fuel.
• Checking backfires. The more you focus on a body part, the more sensations you notice, and prodding and squeezing can create the very symptoms you fear.
• Reassurance is a loan, not a payment. It calms you briefly, then the worry returns with interest.
• The way out is gradual: count your checks, reduce them slowly, and get support if it is running your life. Therapy for health anxiety has excellent long-term evidence.

What health anxiety actually looks like

It is not one big dramatic fear. It is a set of small, repeated habits. The NHS lists the classic signs: frequently checking your body for lumps, tingling or pain, asking other people again and again whether you are alright, worrying that a doctor or a test has missed something, and obsessively reading health information online. Some people do the opposite and avoid anything to do with illness at all.

Two things make it especially sticky. First, anxiety itself produces real physical symptoms: headaches, a racing heart, chest tightness, dizzy spells, odd tingles. If you have read my earlier piece on the physical symptoms of anxiety, you will know these are genuine bodily events, not imagination. But in health anxiety they get read as evidence of disease, which produces more anxiety, which produces more symptoms.

Second, worrying about your health feels virtuous. It feels like diligence. That is exactly what makes the checking so hard to put down.

Why checking makes it worse

Try a small experiment from an NHS self-help guide. Focus on your throat for a minute or so, and swallow three times. Most people notice swallowing suddenly feels effortful and strange. Nothing about your throat changed. Your attention did.

That is the checking trap in miniature. The human body is noisy: twinges, gurgles, flutters and aches are the background hum of a normal working machine. Attention is a spotlight, and wherever you point it, you find things. The more you scan a body part, the more sensations you notice there, and frequent prodding, squeezing and pressing can leave an area genuinely tender, which then feels like confirmation.

Checking feels like gathering information. Mostly it is generating it.

The same goes for symptom searching online, where five minutes of research reliably ends somewhere frightening.

The reassurance trap

Asking a partner, a friend or a GP "but are you sure it is nothing?" works. That is the problem. It reliably lowers the anxiety for a few minutes or a few days, so the habit gets stronger. But as NHS self-help guidance puts it, no amount of reassurance convinces you in any lasting way, and in the long run it keeps the worry going. If reassurance worked, you would only ever have needed it once.

As a GP I try to hold this line kindly: take new symptoms seriously, examine properly, then resist re-testing the same fear on repeat, because repeat testing treats my anxiety about missing something and fuels yours.

Gentle steps that help

None of this means white-knuckling it or ignoring your body. The NHS suggests a gradual approach, and gradual is the important word.

Count first, cut second

For a few days, simply tally how often you check your body, ask for reassurance or look up symptoms. No judgement, just a number. Then reduce it slowly over a week or two. If you check a lump 30 times a day, 20 is a win.

Delay the urge

When the urge to check arrives, put a gap between urge and action. Go for a walk, call someone, make a drink. Urges crest and fall on their own if you give them ten minutes.

Give the thought a second column

Write the worry down, then write a more balanced reading next to it. "These headaches could be something sinister" sits differently once "I have had them during every stressful week this year, and stress is by far the most common cause" is written beside it.

One sensible rule for new symptoms

Agree a policy with yourself, ideally with your GP: a genuinely new, persistent or worsening symptom gets one proper medical assessment. What it does not get is daily home monitoring in between. My guide on when to see your GP about anxiety covers how to have that conversation.

Rebuild the life the worry shrank

Health anxiety quietly removes things: exercise you avoided in case it strained your heart, trips you skipped to stay near your doctor. Adding these back, step by step, is treatment, not recklessness.

When to get more help

If health worries are stopping you living a normal life, or self-help is not shifting them, see your GP. It is a recognised, treatable problem, and you will not be wasting anyone's time. The evidence for treatment is unusually good: in the CHAMP trial across five English hospitals, an average of just six sessions of cognitive behavioural therapy adapted for health anxiety outperformed standard care, and the improvement was still there five years later. In England you can also refer yourself directly to an NHS talking therapies service without going through a GP first. And if a full course of therapy feels like a big first step, short structured sessions, like the ones we built brightloaf around, can be a gentler way in.

The goal is not to stop caring about your health. It is to trade the checking, which feels safe and keeps you frightened, for a calmer watchfulness that lets you get on with your life.
