What is health anxiety?

Health anxiety is thought to consist of a spectrum, so even if you do not fulfill all of the criteria then you may be a person who worries excessively about your health. The psychiatric term for health anxiety is hypochondriasis or hypochondriacal disorder but we will not use the term as it has a pejorative tone. It is derived from Greek and literally means the anatomical area ‘below the cartilage’. This is because it was thought, at one time, that a problem in the guts of a person with hypochondria was, thought to cause various mental disorders. In the 19th century, hypochondria acquired its more specific meaning of fear of disease and preoccupation with one’s health.

The onset of health anxiety can be at any age. However it commonly starts in adolescence or in young adults. Some people with health anxiety have an excessive worry about an illness, which is usually briefer in duration. However the usual course of health anxiety is to come and go depending on various life stresses. Other people with health anxiety have a long-term or chronic health anxiety. It may be more common in women and occurs in about 5% of patients attending a GP’s surgery. We shall discuss the experience of health anxiety problems in more detail below. Not everyone has the same experience of health anxiety – it partly depends on the severity of your problem and the culture you are from.

Physical sensations

The physical sensations that you experience are always real. Only you can tell people what you experience, so don’t let anyone tell you they are imagined or all in your head. However the sensations are often “normal” physiological sensations (like dizziness, tiredness), which are misinterpreted as evidence of a severe illness. Thus a headache may be interpreted as a brain tumour. A lump in one’s body may be interpreted as cancer. Feelings of unreality may be interpreted as a sign of schizophrenia.

Other people might have a long-term illness like epilepsy or diabetes and have symptoms related to their illness but again misinterpret their significance. Physical symptoms can be constant over time or more often change. They can be vague or quite specific.

Intrusive thoughts and images

You may have intrusive thoughts or images about yourself or others being harmed. The threat might be real or imagined and may be from the past (for example, a memory) present or future.

When anxiety dominates the picture, you may be overestimating the degree of danger to yourself or others. Your mind tends to think of all the possible bad things that could occur. This is called ‘catastrophizing’. Your mind will want to know for certain or have a guarantee that you will not die or suffer from a severe illness.

This leads to worrying about how to solve non-existent problems and to control as much of your bodily functions or to plan ahead to deal with all the possible problems that do not arise. The natural desire is to escape or avoid situations that are anxiety provoking. One problem is that your thoughts become fused with past experiences and accepted as facts in the “here and now”. As a consequence, you develop a pattern of thinking which is likely holding a prejudice against information that does not fit with your fears.

We’ll be emphasising the importance of tolerating uncertainty and recognising that thoughts about your health are just that – thoughts, not reality. Learning to accept these negative thoughts and images willingly as ‘just thoughts’ and not buying into them is an important part of overcoming health anxiety.


When you have health anxiety, you may be worrying a great deal about your symptoms, in which you are trying to solve non-existent problems. These usually take the form of ’what if …?’ questions. Examples include “What if I get cancer?” or “What if I have heart disease?” “How will my children cope when I have died?”

Attentional processes

When you are worried about your health, you become more self-focused on your bodily sensations and feelings and at the same time discard negative test results. This tends to make you more aware of how you feel making you more likely to assume that your view of the way you look and the picture in your mind is reality.

Anxiety can produce a variety of physical sensations too, including feeling hot and sweaty, having a racing heart, feeling faint, wobbly or shaky, experiencing muscle tension (for example, headaches), having stomach upsets or diarrhoea, to list a few. These in turn may be further misinterpreted and a vicious circle ensues.


People with health anxiety use a variety of different mechanisms to cope – which usually make the situation worse in the long term.

When the fear is high, you may either try to avoid, distract yourself from your thoughts and feelings or to escape from or avoid situations that remind you of illness or death. Here health anxiety becomes like an illness phobia. Thus you might avoid going to the doctor because you are convinced you will be given bad news. You might avoid people who are ill, hospitals, doctor’s surgeries, funerals, cemeteries, or read anything about illness in the media. Here you may have magical thinking that believes that thinking about bad events could make them happen.

When your doubts are high, you may be excessively checking in the form of self-examination. Examples include checking whether:

  • you have a lump
  • your heart rate is too fast or blood pressure is too high
  • you are losing excessive weight
  • your nervous system is still normal
  • you can still swallow

You might also be checking for information on the internet or in books and in the media. Checking is an example of a “safety seeking behaviour” in which aims to prevent harm and reduce anxiety. People with health anxiety try to adopt ways to improve the way they feel but unfortunately the solutions usually leave them feeling worse and prevent them from testing out their fears. Safety seeking behaviours are a way of “trying too hard” to prevent bad consequences but then the solutions become the problem. We shall look at this more in Chapter x when we look at a psychological understanding of health anxiety. Needless to say, you have to stop all your safety seeking behaviours if you are to overcome your health anxiety successfully.

You may be seeking repeated reassurance from friends or your doctor to find out the cause of your symptoms. When you are dissatisfied by one doctor, you may seek a second and third opinion and so on. Each doctor may order a new set of tests. Some of these tests may have ambiguous findings leading to further tests. You in turn may become very dismissive or dissatisfied with your doctors. Interestingly doctors also become very frustrated with people with health anxiety and may prefer to refer you on to another doctor (rather than a mental health professional). Health anxiety has an effect on your friends and family as when you are preoccupied with your health, you may appear uninterested and distant. This in turn leads people to be frustrated and fed up with you.

The content of worries, safety behaviours and avoidance behaviour are closely related. When the person has to enter a situation that she normally avoids, then the safety behaviours starts to reduce the potential for harm and discomfort. You may then try to avoid thinking about it by distracting yourself or suppressing the thought.

What treatments are available?

If you feel that you or a close relative are affected by health anxiety and would like help or more information, contacting your GP is often the easiest way to get help and further treatment. In England you may refer yourself direct to an Increasing Access to Psychological Therapies (IAPT) centre for CBT. You may also be offered medication such as SSRI anti-depressants.

Does treatment work?

Treatment works for many sufferers of health anxiety if they are prepared to do the homework and to test out some of their worries.

Websites on health anxiety

There are very few websites for health anxiety to get good information. Health Anxiety may be related to OCD. OCD Action is a national charity in the UK. Here is a list of examples of letters to obtain support to obtain a referral to a specialist service.

NHS services

Our specialist clinics for OCD are at the Maudsley Hospital for out-patients and a residential unit at the Bethlem Royal Hospital, Beckenham, Kent. A specialist service for adolescents is at the Maudsley Hospital, London.


Accredited cognitive behaviour therapists (mainly private) can be searched on CBT UK register. I am able to do a private assessment to develop an understanding of the problem and refer you to a suitable therapist.
