Health anxiety symptoms: how it commonly shows up, and what to do about it

If you are in crisis or feel unsafe, please call 999 or go to A&E. For urgent mental health support, call NHS 111 and select the mental health option. Samaritans (116 123, free, 24/7) and Shout (text 85258) are always available.

If you have searched "health anxiety symptoms", there is a fair chance you are trying to work out whether what you are experiencing is health anxiety, or whether it is something physical that has not yet been picked up. That distinction is not one you can settle from a Google search, and it is not one this article is going to settle for you either. Only a GP or qualified mental health professional can do that, and they should.

What this article can do is describe how health anxiety commonly shows up, in thoughts, behaviours and physical sensations, drawing on NHS, Mind and Anxiety UK guidance. If a lot of it sounds familiar and it is affecting your daily life, the right next step is your GP. If you have a new or worsening physical symptom, the right step is also your GP. The two are not in conflict.

The aim here is to help you have a more useful conversation with someone qualified, not to replace one.

What health anxiety actually is

Health anxiety is a recognised mental health pattern. The NHS describes it as a preoccupation with the fear of having, or developing, a serious illness. The fear can focus on one specific condition or move from symptom to symptom over time. It is not a personality flaw and it is not someone "being dramatic". It is the anxiety system getting stuck on the body as its subject matter.

What makes it confusing is that anxiety itself produces real bodily sensations. A racing heart, tight chest, nausea, dizziness, tingling, breathlessness and headaches are all things anxiety can do, and the NHS covers this in its anxiety self-help guidance. So the body is genuinely doing something. It is just doing the thing anxiety does, not the thing the worry says it is doing.

That is part of why the cycle is so sticky. The worry creates sensations, the sensations are read as evidence the worry was right, and the loop goes round again.

How health anxiety commonly shows up

The patterns below are the ones the NHS, Mind and Anxiety UK describe in their health anxiety and anxiety-related content. None of them, on their own, mean you have health anxiety. Several of them showing up persistently and getting in the way of your life is the kind of thing worth talking to a GP about.

Persistent worry about your health. The thoughts come in often and feel hard to dismiss. The NHS describes this as a preoccupation with illness, fear of illness, or fear that current symptoms point to something serious, that does not settle even after reassurance.

Difficulty trusting reassurance. You see a GP and are told everything looks fine. You feel better for a short while, sometimes only minutes, and then the worry comes back. Mind describes this pattern of reassurance not lasting as a feature of anxiety in general, and the NHS flags it within its health anxiety guidance.

Frequent body-checking. Pressing on a spot to see if it still hurts. Examining a mole repeatedly. Taking your pulse. Feeling for lumps. Looking in the mirror. The NHS and UK mental health charities describe checking behaviours as a way the cycle keeps itself alive: every check produces a moment of relief, which the brain learns to repeat.

Searching online for symptoms. Often called "cyberchondria" in plain conversation, though the NHS keeps it under the broader umbrella of reassurance-seeking. You look up a symptom, find a possible serious cause, feel briefly settled, then notice another symptom and start again.

Asking other people for reassurance. Partners, family, friends, repeatedly. "Does this look normal to you." "Have you had this." "Do you think I should go back to the doctor." Mind discusses this in its content on anxiety, and the NHS notes it within its health anxiety guidance.

Avoiding things linked to illness. This is the other side of the coin. Avoiding hospitals, news about illness, certain TV programmes, conversations about death, anywhere a feared topic might come up. Anxiety UK covers avoidance as a common feature across anxiety conditions.

Physical sensations linked to anxiety itself. A racing or pounding heart, tight chest, breathlessness, nausea, dizziness, light-headedness, tingling, sweating, trembling, headaches, muscle tension, stomach upset and tiredness are all things the NHS lists within its general anxiety pages. Health anxiety is anxiety, so it can produce any of these.

Mental and emotional patterns. Difficulty concentrating because the worry keeps interrupting. Sleep that is broken or shallow. Irritability. Feeling on edge or wired. Low mood arriving on top of the anxiety, especially when the worry has been going on for some time. The NHS covers these within its wider mental wellbeing and anxiety guidance.

Life narrowing around the worry. Cancelling plans, avoiding work tasks, struggling to be present with people, time disappearing into research and rumination. Mind describes this pattern of anxiety taking up more and more of daily life as a sign it is worth getting support for.

If a handful of these are persistent, distressing, and starting to shape how you live, that is the kind of pattern worth taking to your GP. You do not have to be certain about anything before you go.

Why this is confusing, and why that is normal

Two things make health anxiety harder to think clearly about than other forms of anxiety.

The first is that anxiety produces real physical sensations, and those sensations can be the very thing you are worrying about. Your heart actually is beating faster. Your chest actually does feel tight. The body is not making it up. The interpretation is the bit that is being driven by anxiety, not the sensation itself.

The second is that some serious illnesses do produce symptoms. Health anxiety does not protect anyone from ordinary illness, and that is part of why "just stop worrying" is unhelpful advice. The job is not to ignore the body. The job is to let people who are qualified to assess the body, like your GP, do that work, while you stop the cycle of repeated checking, Googling and reassurance-seeking that keeps the anxiety running underneath.

For more on what helps with that cycle, see how to stop health anxiety and health anxiety is ruining my life.

When to see your GP

You should see your GP for any of the following:

• A new physical symptom that has not been checked
• A symptom that is getting worse
• A symptom that does not fit a pattern you have already had assessed
• Symptoms that NHS guidance flags as urgent in their own right, such as unexplained weight loss, blood in stool, persistent unexplained chest pain or signs of stroke
• Persistent worry about your health that is affecting your daily life, sleep, relationships or work, regardless of what investigations you have already had

That last one matters. You do not need a clear physical reason to bring up health anxiety with a GP. The persistence of the worry and its impact on your life are reason enough.

In England, you can also self-refer to NHS Talking Therapies at nhs.uk/talk. Waits vary widely. In Scotland, Wales and Northern Ireland, the GP route is the standard one. NHS 111 has a 24/7 mental health option for urgent mental health support.

What not to do

Some honest notes, because most people who land on a page like this have already tried these and felt worse.

• Do not use this article, or any article, to decide whether you have health anxiety. That is a job for a qualified person.
• Do not use this article to decide a physical symptom is "just anxiety" without it being checked. Anxiety can mimic and worsen real symptoms, and ordinary illness still happens.
• Try not to keep researching symptoms in the hope of finding the answer that finally makes the worry stop. That is the cycle, not the way out.
• Try not to treat reassurance from a GP as evidence the worry was wrong, only to start the loop again the next day. Reassurance does not stick when health anxiety is doing the work.

The way through is not more information. It is qualified support and gentle, consistent changes to the cycle.

Quick summary

Health anxiety commonly shows up as persistent worry about illness, difficulty trusting reassurance, frequent body-checking and online searching, asking others for reassurance, avoidance of illness-linked situations, and the same physical sensations anxiety produces in general. None of these on their own confirm anything. Several of them, persistent and getting in the way of daily life, are worth taking to your GP. If you have a new or worsening physical symptom, that is also a GP conversation. The two go together. You do not have to sort this on your own.
