The short version
- Health anxiety is when worry about being ill, or becoming ill, starts to take over your life.
- Checking your body, googling symptoms and asking for reassurance bring short relief and often make the worry stronger.
- Anxiety itself can cause real physical feelings, such as a racing heartbeat or headaches. They are real, even when no serious illness is behind them.
- Have new or worrying symptoms checked by a doctor. After a proper check, repeating tests and visits usually does not help.
- CBT is the main talking therapy, and a 2017 review of 14 studies found it worked well compared with control conditions.
A small ache in your chest. A mole that looks different today. A headache that has lasted two days. You tell yourself it is nothing, but then you open your phone, and an hour later you are sure it is something terrible.
If this is a pattern for you, you are far from alone, and you are not being dramatic. The fear feels completely real. This article explains health anxiety, why it keeps going, and what helps. It is information, not a diagnosis. Only a qualified professional can tell you what is going on.
What is health anxiety?
The NHS describes health anxiety as worrying about being ill, or becoming ill, until it takes over your life. Doctors also use the term illness anxiety disorder. According to the MSD Manual, the term hypochondria is no longer used as a diagnosis because of its negative connotations.
The worry is about what a sensation might mean, more than about the sensation itself. A normal twinge, a skipped heartbeat or a bit of tiredness can set it off.
What does it feel like?
The NHS lists these common signs:
- Constant worry about your health.
- Checking your body again and again for lumps, tingling or pain.
- Searching for health information online or in the media, again and again.
- Asking others to confirm you are not ill.
- Worrying that a doctor or a test may have missed something.
- Avoiding anything to do with serious illness, such as medical programmes, or avoiding exercise as if you were unwell.
Why does it keep going?
Checking, googling and asking for reassurance feel like solutions. They bring a little relief. But the MSD Manual notes that people with illness anxiety keep seeking reassurance, and that when doctors offer it, many feel dismissed and become more anxious.
The worry returns, so you check again. Each time, your mind learns that the only way to feel safe is to check. This is the same loop that drives many kinds of anxiety.
The NHS also points out that anxiety itself can cause symptoms such as headaches or a racing heartbeat, which can be mistaken for signs of illness. The feelings are real. The cause may be anxiety.
Health anxiety or a real illness?
The MSD Manual says illness anxiety disorder is diagnosed when people stay anxious about illness for 6 months or more, even after a medical evaluation has found no serious disorder to explain it.
Only a doctor or mental health professional can tell which is which. A helpful pattern is one good check, with a clear plan, and then not repeating it again and again.
Indian context: many tests, many doctors
If you live in India, you may recognise seeing several doctors, repeating scans and blood tests, asking relatives and searching online. Wanting to be certain is natural. The MSD Manual describes a supportive, trusting relationship with one caring doctor, with regular planned visits, as beneficial.
Another report can feel like it might finally settle things, but the relief may not last. We could not find reliable Indian figures on how common this pattern is, so we give no numbers here.
The MSD Manual says the course is usually long-lasting, with symptoms that ease and return, and that some people recover. So a bad patch does not mean you have failed. Symptoms can settle again, and support can help.
Seeing the pattern clearly is a good first step, and it is nothing to be ashamed of.
What helps
Cognitive behavioural therapy (CBT)
The MSD Manual says CBT may help, and the WHO says psychological treatments based on CBT have the most evidence for anxiety disorders. A 2017 systematic review and meta-analysis by Cooper and colleagues searched 567 studies and included 14 in the analysis. It found a large effect for CBT compared with a control condition after treatment, and the large effect was also found at 6 and 12 months.
The NHS says a GP can refer you for talking therapy, and you can also self-refer to NHS talking therapies in England. In India, a psychiatrist or clinical psychologist can offer CBT.
Medicine
The MSD Manual says antidepressants called SSRIs may help some people. Whether medicine suits you is a decision for a psychiatrist.
Things you can try
The NHS suggests keeping a diary of how often you check your body, seek reassurance or search for health information, and aiming to reduce it slowly. It also suggests writing down health worries next to more balanced thoughts, distracting yourself when the urge to check arises, and gradually returning to avoided activities.

What is the difference between health anxiety and hypochondria?
They describe a similar experience. Doctors no longer use hypochondria as a diagnosis because of its negative connotations. The NHS uses the term health anxiety, and medical texts also use illness anxiety disorder.
How do I stop googling symptoms?
The NHS suggests keeping a diary of how often you search and trying to reduce it gradually, and distracting yourself when the urge comes. Many people find it helps to decide in advance when, if ever, to look.
Can anxiety cause physical symptoms?
Yes. The NHS says anxiety can cause symptoms such as headaches or a racing heartbeat, which may be mistaken for signs of illness. If a symptom is new or worrying, it is still sensible to have a doctor check it.
Why do I need reassurance again and again?
The MSD Manual says people with illness anxiety keep seeking reassurance, and that many feel dismissed and more anxious when doctors offer it. The worry returns and so does the need to ask. CBT helps you reduce that cycle.
Does CBT work for health anxiety?
A 2017 review that included 14 studies found a large effect for CBT compared with control conditions after treatment, also found at 6 and 12 months. Results vary from person to person, and no treatment can promise a cure. A trained professional can guide you.
Should I stop seeing doctors?
No. See a doctor for new or worrying symptoms. The MSD Manual describes a supportive relationship with one caring doctor, with regular planned visits, as beneficial.
