# Health anxiety: what hypochondria is and how to break the loop > You find a lump, search online, and twenty minutes later you are reading five-year survival rates.

That is the loop. *https://mypsicotest.com/en/blog/health-anxiety/ · Published: 2026-09-24 · 8 min read · MyPsicoTest team* You find a lump where there was nothing before. You search online and twenty minutes later you are reading five-year survival rates. You book an appointment, you have the test, it comes back clear. The relief lasts two days, and on the third the doubt arrives about whether they looked at the right thing. That is **health anxiety**, though the manuals no longer call it hypochondria. And one thing is worth saying at the outset, because it is usually the first thing lost in conversations on this subject: the person going through it is not pretending or exaggerating. The fear is real, the symptoms they notice are real, and so is the exhaustion. ## Why it is no longer called hypochondria The term disappeared as a diagnosis in 2013, when the fifth edition of the American DSM manual was published. The word was judged to carry too much pejorative weight — "hypochondriac" has been used as an insult for centuries — and to lump together presentations that were not the same. Two categories took its place. **Illness anxiety disorder**, where the person has few physical symptoms or none but an intense, persistent fear of being ill. And **somatic symptom disorder**, where there are genuinely troublesome physical symptoms — pain, fatigue, digestive trouble — accompanied by disproportionate preoccupation with them. There is another qualification that explains more than any label. The [UK's National Health Service](https://www.nhs.uk/conditions/health-anxiety/) describes health anxiety as **related to obsessive compulsive disorder**, and that reading explains a great deal: the mechanism is less classic hypochondria than obsession and checking. ## How to recognise it The NHS sets out the signs fairly clearly. Health anxiety may be present when someone: - Constantly worries about their health. - Frequently checks their body for signs of illness: lumps, tingling, pain. - Is always asking other people for reassurance that they are not ill. - Suspects that a doctor or medical tests have missed something. - Obsessively looks at health information on the internet. - Avoids anything to do with serious illness, including programmes or conversations. - Acts as if they were ill, for example by avoiding physical activity. Notice that the last two points run in the opposite direction from the earlier ones. That is not a contradiction: they are two faces of the same problem. ## The loop that keeps it going It starts with any ordinary bodily sensation. A twinge, a mole that looks different, dizziness on standing up. The body produces this kind of signal constantly and normally it goes unnoticed. What changes here is the interpretation: the sensation gets read as a sign of something serious. From there one of three behaviours kicks in, each of which brings short-term relief and consolidates the problem in the long run. ### Checking Feeling the area twenty times a day, taking your pulse, looking at your throat, weighing yourself, photographing a mole for comparison. It is the same logic as [compulsive checking in OCD](https://www.nhs.uk/conditions/obsessive-compulsive-disorder-ocd/): a repetitive act used to relieve an anxiety that comes back. Each check calms you for a few minutes and, incidentally, irritates the area, producing a new sensation that confirms the suspicion. ### Seeking reassurance Asking your partner, a relative who works in healthcare, the doctor. Booking again even though the last test was normal. Reassurance works like a very short-acting painkiller: it relieves, and it guarantees another dose will be needed in a few days. ### Avoiding The opposite face. Not going to the doctor for fear of what they might find, skipping the check-up you owe yourself, changing channel when a story about cancer comes on, not visiting someone in hospital. Avoidance lowers the anxiety today and multiplies it tomorrow, because it confirms the subject is unmanageable. ## The internet as amplifier Searching symptoms online has a structural problem: results are not ordered by probability but by relevance and traffic. A headache has hundreds of causes and the overwhelming majority are trivial, but the pages covering the trivial ones are not the most linked or the most read. On top of that, someone searching while frightened does not read the same way. Attention sticks to whatever confirms the suspicion and skims past whatever rules it out. Half an hour later the person has a list of symptoms that fit and none of the hundred that do not. And there is a timing detail: it almost always happens at night, when nobody can be called and nothing can be resolved, and when tiredness reduces the capacity to keep things in proportion. ![Woman reading about symptoms on her phone in the dark in the early hours](https://mypsicotest.com/assets/img/blog-buscar-sintomas-en-internet-1200.webp) ## Why the body produces so many signals This is the piece that closes the circle, and the one that brings most relief to understand. Anxiety **produces real physical symptoms**. The NHS says so directly: it can cause headaches or a racing heartbeat, and those get mistaken for signs of illness. Add muscular tension, dizziness, tingling, chest tightness, digestive trouble, a lump in the throat and breathlessness. They are not imaginary: they are the physiological result of an alarm system that has been switched on too long, something the [US National Institute of Mental Health](https://www.nimh.nih.gov/health/topics/anxiety-disorders) lists among the common manifestations of anxiety disorders. So the loop closes itself: worry generates symptoms, symptoms confirm the worry. And the more closely the body is monitored, the more signals get detected, because selective attention finds what it is looking for. Anyone who pays attention to their own swallowing for five minutes will start to find it strange. ## When to look at it with a professional First, the obvious and important point: **physical symptoms get checked with a doctor**. This article explains a psychological pattern, it does not replace a medical assessment, and health anxiety does not protect you from getting ill. What defines the problem is not going to the doctor but what happens after the doctor says everything is fine. It is worth raising when the worry takes up a good part of the day, when normal test results stop reassuring you after a few days, when appointments and second opinions have piled up, or when the subject has started limiting your life: giving up exercise, avoiding plans, not being able to watch certain things on television. Screening questionnaires help locate where the weight is coming from. The [Anxiety Test](https://mypsicotest.com/en/anxiety-test/) measures worry and physical arousal, which is the base of the picture. The [OCD Test](https://mypsicotest.com/en/ocd-test/) covers obsessions and compulsions separately and fits the repeated-checking pattern well. And the [Stress Test](https://mypsicotest.com/en/stress-test/) is useful if the whole thing started during a period of overload. They are in the [psychological tests](https://mypsicotest.com/en/psychological-tests/) catalogue, free, anonymous and calculated on your own device. They do not diagnose, but they give you a measure to bring to an appointment; our guide on the [Mental health test: what it measures, which ones exist and how to read your result](https://mypsicotest.com/en/blog/mental-health-test/) covers how to read them. If alongside the worry there are images or thoughts that intrude and horrify you, the mechanism may look more like the one described in [Intrusive thoughts: what they are, why they appear and when to worry](https://mypsicotest.com/en/blog/intrusive-thoughts/). ## What works to break the loop The best-supported treatment is **cognitive behavioural therapy**, which here works on three things at once: the interpretation of sensations, the gradual reduction of checking, and exposure to whatever is being avoided. The NHS lists it as the usual referral when self-help is not enough, and how it works in general is covered in [Cognitive behavioural therapy: what it is, how it works and what it treats](https://mypsicotest.com/en/blog/cognitive-behavioural-therapy/). In the meantime, there are concrete measures with good support: - **Keep a record of your checking.** Note how many times a day you examine yourself, search or ask. Simply counting reduces the frequency, and it lets you bring it down gradually rather than trying to stop all at once. - **Agree a plan with your doctor.** Instead of booking every time a doubt appears, agree a review on a specific date and stick to it. It provides security and breaks the cycle of appointments. - **Withdraw reassurance with warning.** Ask whoever provides it to stop, explaining why. Without that agreement beforehand it tends to feel like abandonment. - **Ban the night-time search.** Not searching in general to begin with, but the small-hours ones, which escalate the most. - **Go back to what you avoid.** Resume the exercise, the plans and the conversations you dropped out of fear. It is uncomfortable at first and it is what changes things most. - **Watch the rumination.** Going over symptoms and scenarios mentally for hours clarifies nothing; the mechanism is covered in [Overthinking: why you cannot stop turning things over](https://mypsicotest.com/en/blog/overthinking/). And what does not work: trying to reason yourself out of it, accumulating medical tests, and hunting for the definitive article confirming you are healthy. All three relieve briefly and prolong the problem.

Not under that name any more. Since 2013 the DSM-5 replaced it with two categories: illness anxiety disorder, where there are barely any physical symptoms but an intense fear of being ill, and somatic symptom disorder, where real symptoms come with disproportionate preoccupation. ### Are the symptoms I notice imaginary? No. Anxiety produces real physical symptoms: racing heart, dizziness, muscular tension, digestive trouble, chest tightness. You are not inventing them; what is happening is that their origin is sustained arousal rather than disease. Which is why it matters that a doctor assesses whatever needs assessing. ### Why do normal test results not reassure me? Because reassurance works as short-acting relief. It calms the anxiety for a few days and, in doing so, teaches the brain that the danger was real and needed checking. The next doubt arrives sooner and stronger, and a new test is needed. ### What is its relationship with OCD? A close one. The NHS describes health anxiety as related to obsessive compulsive disorder, and the mechanism is the same: a thought that generates distress and a behaviour — checking, asking, searching — that relieves it momentarily and reinforces it over time. ### So should I not go to the doctor? On the contrary: physical symptoms get checked. What is worth avoiding is the pattern of repeated appointments for the same doubt already ruled out. The useful approach is to agree a schedule of reviews with your doctor and stick to it, rather than booking every time the unease returns. ### Can an online test tell me whether I have health anxiety? It does not diagnose it, but it does help place the problem. A screening questionnaire estimates the intensity of general anxiety and of the obsessive-compulsive pattern, which are the two usual components of this picture. It helps you arrive at an appointment with your information in order.
