What Is Health Anxiety and How's It Treated?

You felt a twinge in your chest, so you looked up what it could mean. An hour later, you’re deep in articles about heart attacks and rare cancers, certain that it’s serious this time. You chest feels tighter with each new article your read. But what starts as a physical concern is often anxiety looking for a place to land. That anxiety is something psychiatrists can treat.

For most people, Googling symptoms or, increasingly, asking AI about them, is just a passing worry. But for some, it becomes persistent and disruptive enough to be a diagnosable condition.

Health anxiety is the everyday term for worry about being seriously ill that won’t let up, even when there’s little or no medical reason for it. In the DSM-5, that takes two forms: illness anxiety disorder and somatic symptom disorder.

What is health anxiety?

Health anxiety is worry about being or getting seriously ill that lasts six months or longer and is out of proportion to any real risk. It usually doesn’t switch off when you get a clean bill of health, even after you’ve received attentive and thorough care.

For many people, a doctor’s reassurance is complicated to begin with. Plenty of patients, especially women, have been dismissed or misdiagnosed before, so it’s understandable to still have doubts when an appointment feels rushed.

The DSM-5, the manual used by clinicians in the U.S. to diagnose mental health conditions, retired the term “hypochondria” and split it into two diagnoses: illness anxiety disorder (IAD) and somatic symptom disorder (SSD).

IAD is intense worry about being sick with few or no physical symptoms. SSD involves real, distressing symptoms, plus outsized worry about what they mean. Of the people who would’ve once been called hypochondriacs, about a quarter fit IAD today, while most of the rest fit SSD.

IAD tends to show up in one of two ways. Some people can’t stop seeing doctors. They book appointment after appointment and regularly ask for more tests. Others avoid doctors entirely, too scared of what they might hear.

IAD shares some traits with obsessive compulsive disorder (OCD), and it often shows up alongside generalized anxiety disorder and panic disorder. But in the DSM-5, it's included as a standalone diagnosis.  A psychiatrist can determine a diagnosis during an evaluation and using your full history.

Why can't you stop Googling your symptoms?

Googling your symptoms brings a few minutes of relief, then more anxiety, which sends you back to search again.

The cycle of health anxiety works like this: you notice a sensation, do an internet search for it, and land on the scariest possible cause. Your anxiety spikes. So you check again, or you ask someone to reassure you. The relief lasts a little while. Then the worry returns, often stronger than before.

Researchers have a name for the online version of this pattern: cyberchondria. It describes health anxiety that gets worse through repeated online searches, feeding a cycle of more searching and more distress.

Receiving normal test result also rarely eases the fear. Instead, reassurance and clean test results tend to be counterproductive. They calm you briefly, but each check quietly teaches your brain that you were only safe because you checked. The fear itself is never actually disproven.

Clinicians call actions like body-checking, repeated Googling, and asking for reassurance “safety behaviors.” The behaviors feel protective, but they actually keep the fear alive because you never get to find out the illness isn't there.

Think of reassurance like pouring water into a leaky bucket. Every search tops it back up, but the leak is still there, so you're back before long. Treatment fixes the leak instead of teaching you to pour faster.

Why do the physical symptoms feel so real?

Your symptoms feel real because they are real. Anxiety switches on the body's fight-or-flight response, which produces genuine physical sensations.

When you feel threatened, your sympathetic nervous system speeds up. It can cause:

• a faster or stronger heartbeat
• shortness of breath
• upset stomach
• muscle tension
• shakiness

These are real physical events, not something you’re imagining.

Paying closer attention to your symptoms only makes it worse. The more you focus on a sensation, the stronger and more alarming it tends to feel. For example, a mild stomach flutter you would normally ignore can become “proof” of something serious once you start monitoring it.

Health anxiety distorts the interpretation of the symptoms. A racing heart is the body reacting to fear and not usually a sign of hidden disease. Treatment can teach you to tell the difference.  

How common is health anxiety?

Health anxiety is far more common than the strict clinical diagnosis suggests. In its broad form, it’s estimated to affect up to 13% of the general population, and up to 20% of people seeing a doctor.

The strict DSM-5 diagnosis of illness anxiety disorder is much rarer. It’s estimated at around 0.1% of the general population and about 0.75% of people seeing a doctor, though exact figures are uncertain because the diagnosis is relatively new.

If you see yourself in this article, you’re experiencing a recognized, well-studied pattern with effective treatment options.

When should you see a doctor about health anxiety?

A new or changing physical symptom deserves a medical checkup. Health anxiety and actual illness aren’t opposites, and you can have both at once. Never ignore a symptom or skip care that you need. Doctors rule out physical causes before diagnosing illness anxiety.

Health anxiety is about what happens after that. It’s going back for test after test that keeps coming back clean, worry that takes over your day, or not being able to feel okay for long, even when the result is good.

When the worry itself starts affecting your work, sleep, or relationships, it’s time to talk to a doctor. A psychiatric evaluation looks at the whole picture instead of one symptom at a time.

How is health anxiety treated?

Cognitive behavioral therapy (CBT) is the main treatment for health anxiety. Medication can help as a second step.

Cognitive behavioral therapy (CBT)

CBT is the most effective treatment for health anxiety, and the research backs it up. A 2024 review found a measurable benefit over other approaches, and the improvement was still there a year to a year and a half later. An older look at 13 trials had similar results. found the same thing.

CBT works by teaching you to push back on catastrophic health thoughts. It also helps you cut down on e checking and reassurance-seeking behaviors, so the fear has less to feed on.

Medication (SSRIs)

Medication usually comes up when therapy alone isn’t enough. Selective serotonin reuptake inhibitors (SSRIs) are the most-studied option. One review of six trials found that SSRIs like fluoxetine, paroxetine, and sertraline eased symptoms of health anxiety.

It’s worth noting those trials were small and short, and they used the older “hypochondria” label rather than today’s criteria.

At Talkiatry, medication is only prescribed when it’s genuinely needed, and usually alongside (not instead of) therapy.  

A few steps you can take today

You don’t have to wait for your first appointment to start managing health anxiety:

• Put a limit on Googling symptoms. When the urge hits, try to wait it out a little longer each time.
• Ask for reassurance less often, whether it’s from family, friends, or your doctor.
• Ease back into the things you’ve been avoiding out of fear, like annual doctor’s appointments or recommended screening tests.  

It’ll feel uncomfortable at first, but that’s the point. You’re showing your brain that the fear fades on its own, without a search or a check.

The bottom line

Health anxiety is common and treatable. The Googling-and-reassurance loop is what keeps it going, and that loop can be broken. A psychiatrist can help you tell anxiety and illness apart and then build a plan to manage the worry.

If the fear is getting in the way of your daily life, talking to someone is a reasonable next step.

Frequently asked questions

Is health anxiety the same as hypochondria?

Not quite. "Hypochondria" is an older term the DSM-5 has retired. It's now two diagnoses: illness anxiety disorder (where there are few or no physical symptoms) and somatic symptom disorder (where there are real, disruptive physical symptoms). "Health anxiety" is the everyday umbrella term for both.

Can health anxiety cause real physical symptoms?

Yes. Anxiety switches on your fight-or-flight response, which can cause a faster or stronger heartbeat, shortness of breath, upset stomach, muscle tension, and shakiness. These are real physical events, not something you’re imagining. What health anxiety distorts is the interpretation of the symptoms.

Why does Googling my symptoms make my anxiety worse?

Searching gives you a hit of relief, then more worry, which sends you back to search again. Researchers call it “cyberchondria.” Every search is a safety behavior that keeps the fear alive by never actually disproving it.

Can you get treatment for health anxiety online?

Yes. Both CBT and medication management for health anxiety can happen over telehealth. At Talkiatry, you take a short online assessment, get matched with a psychiatrist, and meet from home, usually within days.

How do I stop checking my body for symptoms?

The goal isn’t to quit cold turkey, but to check less and wait longer before you do. CBT targets these habits directly. You can start by limiting the internet searches, asking for reassurance less, and easing back into things you’ve been avoiding out of fear. A psychiatrist or therapist can help you through it.
