Health anxiety symptoms and self-check: what to know when illness worry keeps returning

A small twinge in your chest and you are already searching your symptoms. The results mention frightening illnesses, and even after a doctor tells you everything looks fine, the worry is back within days. Worry like this does not come from being weak-willed. It is closer to a protective alarm that rings far too loudly. Here is how that loop works and how to start loosening it.

What is health anxiety? #

Health anxiety is a lasting worry that you have, or will get, a serious illness, one that does not settle easily even after medical reassurance. It used to be called hypochondriasis. The current psychiatric diagnostic manual (DSM-5) separates illness anxiety disorder, where there are few or no physical symptoms but a strong fear of illness, from somatic symptom disorder, where distressing physical symptoms are present and take up a lot of thought and time.

The worry itself is real. It is not faking or exaggerating; it is a protective alarm going off too often and too loudly. That is why ‘just stop thinking about it’ rarely helps, and understanding how the alarm works comes first.

What are the symptoms of health anxiety? #

• You check your body often — taking your pulse, studying your skin in the mirror, focusing on every small sensation.
• You keep searching symptoms — the more you search, the more frightening the possibilities and the bigger the anxiety.
• You check again and again, or avoid it entirely — some people get the same test repeatedly, while others avoid doctors for fear of bad news.
• Reassurance does not last — even after a doctor says you are fine, ‘what if they missed something?’ soon returns.
• Illness stories feel personal — news or a friend’s diagnosis sends your attention straight to your own body.
• Daily life shrinks — the worry disrupts sleep and makes it hard to focus on work or plans.

These pieces connect into a loop: body sensation → ‘what if it is serious?’ → searching or checking → brief relief → attention back on the body → worry. Checking brings relief for a moment but leaves behind the habit of checking again next time. In a meta-analysis of 20 studies, McMullan et al. (2019) found that people with more health anxiety searched for health information online more (r = 0.34), and that health anxiety was even more strongly linked to ‘cyberchondria’, searching that leaves people more anxious (r = 0.62).

How can I self-check for health anxiety? #

A widely used self-check is the Whiteley Index. Building on the questionnaire Pilowsky developed in 1967, Fink et al. (1999) shortened its 14 items to seven (the Whiteley-7). It asks about worry over illness, preoccupation with body symptoms and how hard it is to feel reassured by a doctor.

If physical symptoms such as headaches, stomach trouble or dizziness also bother you often, try the physical symptoms check as well. The PHQ-15 asks how much 15 common physical symptoms have bothered you over the past four weeks and was developed by Kroenke et al. (2002) with 6,000 patients.

Both are tools for getting a sense of where you are now, not diagnoses. New symptoms or symptoms that have changed should be checked by a doctor first; if the worry still takes over daily life after that, it is time to work on the worry itself.

Can health anxiety get better? #

Yes. Health anxiety has been studied extensively. In a meta-analysis of 19 randomized controlled trials, Axelsson and Hedman-Lagerlöf (2019) found that cognitive behavioral therapy reduced health anxiety by a moderate to large amount, and the effects largely held 12 to 18 months after it ended. Cognitive behavioral therapy delivered online showed effects similar to face-to-face sessions.

Cognitive behavioral approaches involve examining ‘what if it is serious?’ thoughts, gradually cutting back on reassurance habits such as checking and searching, and building the ability to live with uncertainty. To learn how these thoughts work, read what is cognitive behavioral therapy?.

Five things to try when health worries come up #

1. Count how often you check — note how many times a day you take your pulse or search symptoms. Once you know the number, you have something to reduce gradually.
2. Set a worry time instead of searching — jot the worry down and look at it only during a set 15 minutes in the evening. By then it has often shrunk. Our guide to overthinking describes a similar practice.
3. Name the sensation and let it pass — say without judgment, ‘there is a tight feeling in my chest right now’, then watch for a few minutes how it changes.
4. Ask for reassurance less — set a limit on how often you ask family ‘do I look okay?’ and lower it step by step. Letting them know about this practice ahead of time helps.
5. Stick to your plans for the day — keep doing what you meant to do even when worry rises. This practices not letting worry set your schedule.

If it feels hard to tell someone about a worry the moment it rises, you can start by sorting through it one thought at a time in a conversation.
