Understanding health anxiety

What is health anxiety?

The United Kingdom's National Health Service (NHS) defines health anxiety as “spending so much time worrying you’re ill, or going to get ill, that it starts to take over your life.”

Unlike temporary health worries, this anxiety persists, even when symptoms are mild, medically explained, or entirely absent. People with health anxiety often become hyperaware of bodily sensations, misinterpreting normal changes as signs of serious illness.

Health anxiety shares features with obsessive-compulsive disorder (OCD) - recurring thoughts that drive repetitive behaviours, such as repeatedly checking your body or seeking reassurance.

How it manifests?

You may experience health anxiety if you:

  • Constantly worry about your health or imagine worst-case scenarios
  • Check your body repeatedly for signs of illness
  • Seek reassurance from others or multiple medical opinions
  • Worry that tests or doctors may have missed something
  • Spend time searching online for health information
  • Avoid anything related to illness (e.g., medical TV shows)
  • Experience physical sensations caused by stress itself

Daily challenges

Living with health anxiety can feel relentless and exhausting, a cycle of fear and temporary reassurance. Thoughts like “What if they missed something?” or “I can’t trust my body” often lead to:

  • Trouble concentrating or staying productive
  • Social withdrawal and relationship strain
  • Disrupted sleep or avoidance of certain activities
  • Physical stress symptoms that reinforce anxiety

Health anxiety can quietly dominate daily life, making it difficult to relax or focus on what truly matters.

How common is it?

Despite being recognised by the NHS and major mental health organisations, health anxiety often goes underdiagnosed.

This can be due to:

  • A focus on physical rather than psychological symptoms
  • Lack of awareness among sufferers and professionals
  • Overlap with other conditions like OCD or GAD
  • Limited screening or inconsistent terminology (“hypochondriasis”)
  • Stigma that prevents people from seeking help

It is estimated that 3-5% the UK population, around 2–3 million people (Tyrer et al., 2011) have a form of health anxiety. Recent reviews suggest that globally, between 2.1% and 13.1% of adults experience clinically significant health anxiety, depending on how it’s defined and measured (Alberts et al., 2023). This equates to between 170 million to 1 billion people. 
 

ThoughtStore and anxiety

Why ThoughtStore focuses on health anxiety

  • It’s common, yet under recognised

Despite affecting millions, health anxiety is frequently overlooked or misdiagnosed. ThoughtStore was built to give sufferers the tailored support they’ve been missing.

  • It’s repetitive and behaviour-driven

Health anxiety involves cycles of checking, reassurance-seeking, and Googling symptoms. ThoughtStore helps you track these patterns, turning awareness into empowerment.

  • It complements CBT-style approaches

Cognitive Behavioural Therapy (CBT) is one of the most effective treatments for health anxiety. ThoughtStore acts as a reflection tool, a safe space to record thoughts and share insights with a therapist.

  • It’s a silent mental health burden

Many people with health anxiety function day-to-day; working, caring, coping - yet suffer privately. ThoughtStore acknowledges their experience and provides a structured way to manage it.

  • It makes ThoughtStore different

Most wellness apps take a broad, generic approach. ThoughtStore is purpose-built for a specific, underserved need. It helps users understand, track, and ease the repetitive loops of health anxiety.

How ThoughtStore can help

While not a replacement for therapy, ThoughtStore acts as a daily companion for reflection, insight, and self-awareness.

It offers:

  • A gentle way to log and track health-related thoughts, worries, or symptoms 
  • Support for identifying patterns in triggers and responses 
  • A quick count feature, helping users build awareness of frequency 
  • Insight summaries that highlight trends over time, which can be empowering to review independently or with a therapist

By externalising anxious thoughts, you can begin to challenge them more effectively, rather than letting them build in silence. This practice of observing patterns can also help create distance from the anxiety and facilitate self-compassion, especially when you begin to identify similar thoughts, or times at when these thoughts appear.

In the long term, ThoughtStore can support:

  • Reduced reassurance-seeking behaviour    
  • Better collaboration with healthcare professionals
  • More confident self-management between therapy sessions

Made from experience

Health anxiety is more than worry. It’s a persistent, looping fear that can consume daily life. ThoughtStore helps you externalise those thoughts, spot patterns, and reclaim a sense of balance.

Awareness is the first step toward calm.

ThoughtStore was built from lived experience, by people who understand how consuming health anxiety can be. It’s designed to help you notice your thoughts, see the patterns, and gently step back from them, one moment at a time.
