Health Anxiety

Health anxiety (previously and still sometimes called hypochondria and sometimes hypochondriasis) is a condition that consists of a preoccupation with having a serious illness or a fear of developing a serious illness.

Despite receiving reassurance from health professionals, people with health anxiety either believe they already have an illness or are in imminent danger of developing one. Seeking reassurance from doctors or the internet provides relief, but just like in OCD, such compulsions only offer temporary relief before the fear of illness returns.

Despite medical reassurance the person suffering will spend so much time worrying that it starts to significantly take over their life.

Those who are affected by health anxiety/illness phobia are convinced that harmless physical sensations are indicators of serious disease or severe medical conditions. For example, if a person experiencing health anxiety feels their chest is getting tight, they may believe that they are having a heart attack.

You may have health anxiety if you:

  • Constantly worrying about your health
  • Frequently checking your body for signs of illness, such as lumps, tingling or pain
  • Obsessively looking at health information on the internet or in the media (for reassurance)
  • Often asking family or doctors for reassurance that you’re not ill
  • Worry that your doctor or medical tests may have missed something
  • Avoiding anything to do with serious illness, such as medical TV programmes like Casualty or Holby City
  • Act as if you were already ill (for example, avoiding physical activities)

The onset of health anxiety can be at any age, but is usually more frequent in females. However  commonly it starts in adolescence or in young adults, but can be sporadic (without treatment) depending on various life stresses.

Is Health Anxiety a form of OCD?
While there are some overlapping symptoms between the two disorders, and it’s also possible for someone to be diagnosed with both OCD and health anxiety, they are defined as separate disorders. One significant difference worth noting is that usually, those with OCD have better insight into their problem compared to those with health anxiety, who truly believe they have a serious illness.

Whilst OCD is listed in its own category, health anxiety in the Diagnostic and Statistical Manual of Mental Disorders (DSM) is listed under a category of Somatic Symptom and Related Disorders as either a ‘somatic symptom disorder’ (Code: 300.82) or ‘illness anxiety disorder’ (Code: 300.7), depending on the specific symptoms displayed.

Treating Health Anxiety
The treatments for health anxiety are very similar to those for OCD, with the treatment found to be the most effective being a talking therapy called Cognitive Behavioural Therapy (CBT). Some people find they also need the additional support of anti-depressant medications to help them through the therapy which will usually be a form of anti-depressant SSRI (Selective Serotonin Re-uptake Inhibitor) medications.

There are some things you can do to help monitor the impact of health anxiety:

  • Note how often you check your body for signs of illness symptoms.
  • Note how often you ask people for reassurance.
  • Note how often you look at health information online.
  • Try and gradually reduce the amount of times you do these things.
