Understanding Health Anxiety: Causes, Symptoms, and When to Seek Help

By Dr Daniel Gordon • 27, Feb 2025


If you’ve ever found yourself constantly worried about having or developing a serious illness, or you spend a significant part of your day looking up symptoms online, you may be experiencing health anxiety. Although it can feel isolating and distressing, understanding why it happens and how to recognise the signs can be the first step toward getting the right support.


In this article, we’ll explore what health anxiety is, why it might have increased in recent years, and how to tell the difference between normal health concerns and clinical health anxiety. We’ll also discuss why continuity of care is so crucial for anyone dealing with these issues and how to seek professional help if you need it.

1. Why Anxiety About Health Has Increased

The Impact of COVID-19

It’s undeniable that the COVID-19 pandemic heightened fears around health for many people. Daily news updates about infection rates, hospitalisations, and mortality, combined with lockdowns and social isolation, created an environment where it felt like we were all under threat. Even as the global situation has evolved, this lingering sense of vulnerability has not necessarily disappeared. Many patients have described heightened anxiety about germs, infections, and their overall well-being.

General Anxiety vs. Health Anxiety

Before diving deeper, it’s important to acknowledge that anxiety itself is a natural emotion. Humans evolved to feel anxious for survival reasons. A certain amount of worry can help you prepare for important events, stay vigilant in dangerous situations, and generally take care of your health. The trouble arises when this worry becomes disproportionate to the actual risk or starts to significantly disrupt your daily life. That’s often where health anxiety begins.

2. Defining Health Anxiety

Health anxiety, in simplified terms, is a preoccupation with having or developing a serious illness. It used to be commonly referred to as “hypochondriasis,” but modern understanding has refined it into what we now call health anxiety or “Illness Anxiety Disorder” (depending on the diagnostic framework used).

People with health anxiety may:

  • Fear serious conditions like cancer, heart disease, autoimmune disorders, or infections.

  • Interpret normal bodily sensations—like a slight headache or mild fatigue—as signs of severe illness.

  • Spend excessive time researching symptoms online, often ending up on worst-case scenario websites.

  • Frequently visit doctors, emergency rooms, or hospitals for reassurance—or, conversely, avoid medical settings out of fear of what they might discover.

This cycle can become self-perpetuating: the more anxious you feel, the more physical symptoms of stress your body produces (rapid heartbeat, sweating, trembling), which then reinforce the belief that something is physically wrong.

3. Signs and Symptoms of Health Anxiety

So, how do you distinguish regular health worries from something more disruptive like health anxiety? Here are some common indicators:

  1. Excessive Worry About Serious Illness. You find yourself catastrophizing or ruminating about having a life-threatening condition, even if there’s minimal or no evidence to support that belief.

  2. Frequent “Checking” Behaviours. This might involve checking your pulse repeatedly, examining your skin for new moles or lumps, or prodding at areas of your body for signs of pain or swelling.

  3. Constant Reassurance-Seeking. You may visit multiple doctors, consult various specialists, or regularly seek comfort from friends and family. Any relief gained from reassurance is usually short-lived.

  4. Excessive Research. Spending large chunks of time scouring the internet for symptoms and diagnoses. This can easily spiral into reading about worst-case scenarios, which only heightens anxiety.

  5. Heightened Distress from Minor Bodily Changes. Minor or normal bodily changes—a slight cough, a fleeting headache—can trigger intense worry and panic.

If these symptoms persist for at least six months and interfere significantly with your ability to function at work, care for your family, or enjoy social activities, it could indicate a clinical level of health anxiety.

4. How Health Anxiety Becomes a Vicious Cycle

One of the most challenging aspects of health anxiety is how physical symptoms of anxiety feed into fear about being seriously ill. When you’re anxious, your body releases stress hormones like adrenaline and cortisol. This can lead to real, tangible symptoms such as:

  • Rapid heartbeat

  • Muscle tension or pain

  • Sweating or shaking

  • Shortness of breath or chest discomfort

If you’re already on high alert, these sensations seem like undeniable proof of a physical illness. The more you worry, the more anxious you become, and the more pronounced these sensations become—creating a loop that can be incredibly difficult to break.

5. Normal Concern vs. Clinical Health Anxiety

It’s essential to note that not everyone worried about their health automatically has health anxiety. For instance, if you have a strong family history of a particular illness, like breast cancer or a hereditary heart condition, you might be more vigilant about screenings and check-ups. That’s a perfectly rational response to an elevated risk profile.

In health anxiety, however, the fear is often disproportionate to the actual risk, and it persists despite normal test results or reassurances from healthcare professionals. This disproportionate worry can extend to the point where it disrupts daily life and causes emotional distress.

6. Seeking Medical Care vs. Avoiding It

Interestingly, people with health anxiety may fall into two opposite patterns of behaviour regarding medical care:

  1. Frequent Healthcare Visits. These individuals may routinely schedule doctor’s appointments, request multiple tests, or show up in emergency rooms, seeking reassurance that nothing is seriously wrong.

  2. Avoidance of Healthcare Settings. Conversely, some people are so terrified of receiving bad news that they avoid hospitals, clinics, and check-ups altogether. They might worry they’re “wasting the doctor’s time,” or they fear that any test could confirm their worst fears.

Neither approach is particularly healthy: constant reassurance-seeking doesn’t break the cycle of anxiety, and avoidance can prevent early detection of genuine medical issues.

7. Why Recognizing Health Anxiety Matters

Identifying that you might have health anxiety is the crucial first step toward effective management. Treatments for health anxiety often differ from those for general stress or depression. While there is overlap—like cognitive behavioural therapy (CBT) and sometimes medication—health anxiety typically calls for specialized strategies to address specific patterns of fear and reassurance-seeking.

  • Continuity of Care. One of the most valuable assets for someone with health anxiety is having a consistent medical provider. A doctor who knows your history and understands your anxieties can offer balanced reassurance without enabling constant health checks or trivialising your concerns.

  • Balanced Reassurance. The goal is to reassure you in a way that reduces panic, but not to the point of conducting unnecessary tests or fuelling the notion that every concern requires immediate investigation.

  • Psychological Support. Psychotherapies, particularly CBT, can help you reframe catastrophic thinking patterns, reduce checking behaviours, and ease the cycle of anxiety. Some individuals also benefit from group therapy or support groups where they can share experiences in a safe environment.

8. When to Seek Professional Help

If you suspect that your worries about health are escalating beyond normal concern, consider taking these steps:

  1. Talk to a Healthcare Professional. Start by scheduling an appointment with a trusted doctor. Explain your symptoms—both physical and psychological—and describe how they’re affecting your daily life.

  2. Explore Therapy Options. Ask your doctor about a referral to a psychologist or a therapist who specialises in anxiety disorders or specifically in health anxiety. Cognitive Behavioural Therapy is often highly effective in addressing health-related fears and compulsions.

  3. Consider Medication if indicated. While medication isn’t always necessary, some people benefit from short-term or long-term use of anti-anxiety medications or antidepressants. This should always be guided by a medical professional.

  4. Build a Support System. Friends, family, or support groups can offer understanding and encouragement. If you find that your loved ones are overwhelmed by your health concerns, a mental health professional can provide additional support strategies.

  5. Evaluate Online Information Critically. If you’re prone to symptom-checking online, try to stick to reputable sources and be aware of your emotional state. Anxiety can make you hyper-focus on the scariest possibilities.

9. Conclusion

Health anxiety can feel like a relentless, life-altering condition—especially when every new ache or twinge triggers alarm. Yet, it’s important to remember that anxiety itself is a normal human response that becomes problematic when it overshadows the realities of your daily life. Recognizing the signs, understanding why you may be experiencing heightened health worries, and seeking professional help are critical steps toward regaining control.

Whether you find yourself scheduling endless check-ups or avoiding medical care altogether, talking to a doctor who understands health anxiety can make a profound difference. With the right combination of care, balanced reassurance, therapy, and, if necessary, medication, it’s entirely possible to break the cycle of fear and live more confidently—trusting your body without being consumed by dread.

If this resonates with you and you think you may be struggling with health anxiety, reach out to a healthcare professional for support. Remember, you’re not alone—and taking that first step could make all the difference to your overall well-being.
