Health anxiety: someone to talk to when you can't stop checking symptoms
Last updated . Written by the Vent Now team. Vent Now is built with a licensed therapist on the team.
If you can't stop worrying about your health, the conversation that helps ends in a plan, not another search: get real symptoms checked by a doctor once, agree on what would mean coming back, and practice not re-checking in between. Health anxiety runs on body checking, symptom searching and reassurance that wears off, and cognitive behavioral therapy (CBT) treats it well. 1 2
If you're mid-search right now, you can tell Aspen, the AI companion in Vent Now, what you're afraid of instead. Aspen can't assess symptoms, but it can help you step out of the loop. .
If you might hurt yourself or someone else, call or text 988, or call 911 now.
What is health anxiety, and when is it more than ordinary worry?
Everyone worries about their health sometimes, especially after a scare or when someone close gets sick. Health anxiety is when the worry starts to take over: checking your body for lumps, tingling or pain, asking people again and again whether you're okay, reading health information compulsively, worrying that a doctor or test missed something, or avoiding anything to do with illness. 1 Anxiety also causes physical sensations of its own, like headaches or a racing heart, which can then feel like proof that something is wrong. 1
Psychiatric diagnostic criteria describe two related conditions. In illness anxiety disorder, a person stays preoccupied with having or getting a serious illness for six months or more, with no symptoms or only mild ones, even after a medical evaluation hasn't found a serious problem. 3 In somatic symptom disorder, the physical symptoms are real, sometimes from a diagnosed condition, but the worry, thoughts and time spent on them are out of proportion and disrupt daily life. 4 Neither means the symptoms are imaginary, and only a clinician can say whether either fits you.
The NHS describes health anxiety as related to OCD, 1 and it runs on a similar loop. A sensation sets off a frightening thought, checking or asking brings relief, and the relief fades. Each round of checking makes the next one feel more necessary.
How to stop re-checking without ignoring your body
Start with the first step if you haven't seen a doctor about the symptom. The rest are self-help steps drawn from CBT for health anxiety and NHS self-help advice. 1 2
1. Get it checked once, with a plan
A steady relationship with one doctor, with visits scheduled ahead rather than booked every time fear spikes, is part of how illness anxiety is managed. 3 A written plan also gives you something to turn to besides a search bar.
- Book one appointment with your regular doctor rather than several with different ones.
- Write down the symptom, when it started, what makes it better or worse, and what you're afraid it is. Say the fear plainly: "I'm worried this is MS."
- Ask, "What would make you want to see me sooner, and when should I come back if nothing changes?" Write the answer down.
- Tell your doctor that health worry is hard for you. It helps them plan follow-up with you.
- Between visits, let that list guide you rather than how scared you feel. Red-flag symptoms are still a 911 call.
2. Keep a checking log
The NHS suggests noting how often you check your body, ask for reassurance or look up health information, then gradually cutting back over a week. 1 Counting turns an automatic habit into something you can see.
- For three days, tally every check: pressing on a lump, taking your pulse, studying a mole in the mirror, opening a health app, asking someone.
- Note what set it off and how long the relief lasted.
- Pick one kind of checking and set a daily limit a little below your average.
- Lower it again every few days. Fewer is the goal at first, not zero.
3. Postpone the search
A meta-analysis of 20 studies with 7,373 people found health anxiety strongly linked with cyberchondria, repeated online health searching that leaves people more distressed. The studies were correlational, so they can't show which causes which. 5 Searching isn't a reliable check anyway: in a 2015 audit of 23 online symptom checkers, the correct diagnosis was listed first about a third of the time. 6
- When the urge to search hits, write the question down instead.
- Wait 30 minutes and do something with your hands in the meantime.
- When the time is up, compare the question with your doctor's "come back if" list. If it's on the list, call the office. If it isn't, and it's the same thing your doctor already checked, cross it off. If it's a new or different symptom, call your doctor's office during hours instead of searching.
- Don't swap the search engine for a chatbot. Asking an AI, Aspen included, whether a symptom is serious is the same loop.
- Delete symptom sites from your bookmarks.
4. Write the worry, then a balanced version
Writing your health worry in one column and a more balanced thought in the other is one of the NHS self-help steps for health anxiety. 1 The point isn't to prove you're healthy, which nobody can do. It's to make room for the uncertainty everyone lives with.
- In the first column, write the exact fear: "This headache means a brain tumor."
- In the second, write what else could explain it and what you actually know: "I've slept badly all week. Stress can cause headaches. My doctor gave me a plan."
- Add one line about uncertainty: "I can't be 100% sure, and I can live with that until my follow-up."
- Write it once and move on. Rewriting it ten times turns it into another kind of checking.
5. Get back to what you've been avoiding
NHS self-help advice for health anxiety includes doing something else when the urge to check hits, and gradually returning to activities you've dropped because of health worries. 1
- When you notice the urge to check your body, take a short walk or call someone.
- List what you've stopped doing because of health fear: exercise, plans with friends, certain TV shows, even routine checkups.
- Pick the easiest one and do a small version of it this week.
- If you've avoided exercise because of heart or breathing worries, ask your doctor what's safe for you first.
Why doesn't a clear test result settle it?
Reassurance does work, briefly. In a study of 60 people told after a gastroscopy that nothing was seriously wrong, worry dropped right afterward. For people with high health anxiety, it rebounded within 24 hours to a week and was still up a year later. 7 It was one small study, but it matches one of the signs of health anxiety the NHS lists: worrying that the doctor or test missed something. 1
An AI chatbot can speed the loop up. It answers at 3am, never tires of the question and can always come up with one more possibility. Aspen can't assess symptoms, so it shouldn't be used that way. You can tell Aspen at the start, "If I ask whether this is serious, point me back to my plan."
The way out isn't a better answer. It's a plan you made with a doctor, and practice living with the gap between appointments.
Which symptoms shouldn't wait, even with health anxiety?
Health anxiety doesn't protect you from real illness, and having it is no reason to sit on an emergency. A symptom that's new, or different from your usual worries, is worth a call to your doctor's office. If you can't tell whether it's an emergency, call your doctor's after-hours line or a nurse line rather than searching. Some symptoms need 911 even if you've had false alarms before. If a stroke is possible, call for an ambulance rather than driving, and note when the symptoms started. 8 Call 911 right away for:
- Chest pain or discomfort, especially with shortness of breath, feeling weak, lightheaded or faint, or pain in the jaw, neck, back, arms or shoulders. 9
- Sudden numbness or weakness in the face, arm or leg, especially on one side, a drooping face, an arm that drifts down, or slurred or strange speech. 8
- Sudden confusion, trouble seeing, dizziness, loss of balance or trouble walking. 8
- A sudden, severe headache with no known cause. 8
- Sudden trouble breathing or fainting. 10
What if you already have a diagnosis?
Living with a real condition, or after a cancer or heart scare, gives worry something solid to hold onto, and some watchfulness is sensible. Somatic symptom disorder can be diagnosed alongside a real medical condition when the response to it is much more intense than the condition calls for and takes over daily life. 4 Only a clinician can make that call, and it isn't the same as saying you're overreacting.
Ask your care team for a written plan: which changes need a same-day call, which can wait for your next visit, and which are expected with your condition. Then use it the way you'd use a "come back if" list. Fear of a flare or a recurrence is worth bringing to a therapist as well, alongside your medical care rather than instead of it.
When to get more help
Checking out a real symptom is sensible. It's worth getting help for the worry itself if:
- You've been preoccupied with having or getting a serious illness for six months or more, despite a medical evaluation. 3
- Checking, searching or asking for reassurance takes up a big part of your day, or you can't stop when you want to.
- Relief after a normal test or appointment lasts hours or days, not weeks.
- You're avoiding doctors altogether because you're afraid of what they'll find.
- You've had low mood, hopelessness or loss of interest for two weeks or more, or you're having panic attacks.
- You have thoughts of not wanting to be alive. Call or text 988.
Look for a therapist who uses cognitive behavioral therapy for health anxiety. A meta-analysis of 19 randomized trials found moderate to large effects that mostly held 12 to 18 months later. About two-thirds of people responded, about half reached remission, and therapist-guided internet CBT worked about as well as face-to-face. 2 Keep your primary care doctor involved: guidance on illness anxiety recommends staying under their care while you get mental health treatment. 3

What this can look like with Aspen
It's 2am. Someone has felt a twinge in their chest on and off for weeks, had a normal heart check last month, and has been reading about heart attacks for an hour.
An illustration written by the Vent Now team, not a real user's conversation. Aspen's replies are generated by AI and will differ.
You: my chest has this twinge again and I've been reading about heart attacks for an hour. can you just tell me if it's serious
Aspen: I can't assess symptoms, so I can't tell you that. One urgent check first: is it crushing pain, or does it come with shortness of breath, feeling faint, or pain in your arm, jaw or back? If so, call 911 now.
You: no. it's a little twinge, same as the last few weeks. my doctor did an ECG last month and said it was normal
Aspen: Okay. Did your doctor tell you what would mean coming back sooner?
You: if it got worse, or came with breathlessness or fainting. it hasn't. but what if they missed something
Aspen: That "what if they missed something" feeling sounds exhausting. Has the last hour of reading made it smaller or bigger?
You: bigger. way bigger
Aspen: Then could you try putting the search off? Write the question down, and in 30 minutes check it against your doctor's list.
You: ok. I wrote it down. it's not on the list
Aspen: Then it's a question for your next appointment, not the search bar. What would help you settle until morning?
You: maybe a podcast and putting my phone across the room
Aspen: That could work. If this keeps taking over your nights, a CBT therapist who treats health anxiety could help. Want to come back to that tomorrow?
How Vent Now fits
Vent Now is somewhere to put the fear into words at 2am instead of typing it into a search bar. You can ask Aspen to help you write your "come back if" list before an appointment, keep a checking log, postpone a search, or write out a balanced version of the worry. Aspen remembers context from past conversations, so you can pick up where your plan left off.
Aspen is not a doctor or a symptom checker and can't tell you whether a symptom is serious. Asking it to is the same reassurance loop as searching. Aspen isn't a therapist either. Symptoms belong with a doctor, red-flag symptoms with 911, and health anxiety that's running your life with a CBT therapist.

Common questions
Is health anxiety a type of OCD?
Not exactly, but the NHS describes it as related to OCD. 1 Both involve frightening thoughts, checking and reassurance seeking, and both are treated with forms of CBT. A clinician can tell you whether your worry fits health anxiety, OCD, both or something else.
What if my doctor really did miss something?
It can happen, which is why a plan is better than a single "you're fine." Ask what follow-up makes sense, what would change the picture and when to come back. If you're still uneasy, one second opinion with your records is reasonable. Going from opinion to opinion tends to work like other reassurance, with relief that doesn't last. 7
Should I stop using my smartwatch or health apps?
If your doctor has asked you to track something, like blood sugar or blood pressure, keep doing it and ask how often to check and which numbers mean a call. If not, and you notice you check readings for reassurance, try turning off the alerts for a week and see whether the worry gets louder or quieter.
Can medication help with health anxiety?
Sometimes. Antidepressants are used for illness anxiety in some cases, alongside therapy and regular visits with a doctor. 3 Whether it makes sense for you is a decision to make with your doctor.
