I'm not sick but I'm not well


This phrase got me thinking: what happens to people who do not have an identifiable disease, but still feel unwell; when the tests do not reveal any pathology, but they still have symptoms? They get a label, that’s what, because doctors cannot say: “Your tests are normal and you do not have any evidence of an underlying disease process. Further opinions and investigations are unlikely to help, and may lead to unnecessary and potentially harmful treatments”.

I don’t have time for a discourse on medicalisation, but I wanted to ask: What label do these people get? It turns out that it depends on the specialty training of the doctor that sees them.

Most specialties have a diagnosis that can be used to label people with vague, non-specific symptoms without clear underlying pathology. If patients complain of bloating, muscle pains, weakness, fatigue, headaches, dizziness, sore spots, chest tightness, shortness of breath etc., the diagnosis that they get depends on who they see. The following are the diagnoses you get from various specialists:

Gastroenterologist:                Irritable bowel syndrome or dyspepsia
Gynaecologist:                      Chronic pelvic pain or premenstrual syndrome
Cardiologist:                         Atypical chest pain
Rheumatologist:                    Fibromyalgia
Respiratory physician:           Hyperventilation syndrome
Infectious diseases:               Chronic (post-viral) fatigue syndrome
Neurologist:                         Tension headache, migraine, restless leg syndrome
Dentist:                                Temporo-mandibular joint dysfunction
Ear, nose and throat:             Globus syndrome
Allergist:                              Multiple chemical sensitivity
Urologist:                             Interstitial cystitis, painful bladder syndrome
Psychiatrist, GP:                   Depression, anxiety disorder, somatoform disorder

The names for these conditions change over time, and new ones get thrown in to the mix. This list is not exhaustive: the psychiatrists have a lot more diagnoses at their disposal that can easily be retro-fitted to any vague set of symptoms (many more diagnoses than they had during the Rosenhan Experiment). And now sports medicine physicians are diagnosing all sorts of things, often labelled “[INSERT BODY PART HERE] dysfunction” (I love the term “dysfunction”, which basically means “something is wrong” – that’s what makes it a label, not a diagnosis).

So do these ‘diagnoses’ overlap?
Yes, yes they do. This study from the Lancet in 1999 reviewed the subject and found considerable overlap in the diagnostic criteria for these conditions. This is because the diagnostic criteria rely so much on subjective complaints from the patient, rather than the findings from blood tests or X-rays. Not only was there significant overlap between the diagnostic criteria, but the same kinds of patients got these conditions (here), and they were often treated the same way (antidepressant medication and psychological therapies). There is a more accurate label, but it is rarely used (for obvious reasons): Medically Unexplained Symptoms (click here for an overview). More evidence on the overlap of diagnoses between specialties can be found here, here and here.

These conditions used to be called Functional Somatic Syndromes, but the group label changes. Central Sensitivity Syndromes is a recent label used to explain (and group) the syndromes listed above (see here and here). Basically the theory is that these people have nervous systems that are more “sensitive”, so that patients are more likely to complain of pain. I think that this label is at best, poorly supported, and at worst, simplistic, unproven and a backward step in understanding the real reasons for the existence of these syndromes (as psychological and social constructions, or the somatic manifestations of psychosocial influences).

I shouldn’t worry, it looks like that label will soon be replaced by Bodily Distress Syndrome (I am not kidding, here is the link). Nortin Hadler tries not to medicalise this by calling it the Syndrome of “out of sorts”, but this sounds dismissive to the patients, so it will never be accepted.

How do these patients end up with such (apparently) different labels?
Here is how it works. The patient complains of generalised symptoms, and the doctor fits those symptoms into a recognisable syndrome (patterns of symptoms) that fits his area of knowledge and expertise. For example, the rheumatologist will look for tender points: “Does it hurt if I press here? And here?” “Yes!” says the patient who is subconsciously striving for a label to validate and legitimise their symptoms. Once you get 11 tender points you have satisfied the criteria for fibromyalgia.

For gastroenterologists, they will ask questions about changing bowel habits, the patient will answer in the positive, and then the diagnosis is established. All the other symptoms are relegated to peripheral manifestations of the label; in this case, Irritable Bowel Syndrome.

Doctors tends to see what they want to see or what they know, and they guide the patient into known categories of symptoms that fit the syndrome they are expecting, or the only suitable one they know.

Doctors haven’t cornered the market.
I am waiting to meet a patient who came out of a visit to a chiropractor without a diagnosis of spinal malalignment/subluxations that required correction, regardless of what they went in for. As you can see, when we label, we reach for the closest, most familiar labels: the ones we were taught, and the ones for which we provide the treatment. Same goes for every other alternative medicine provider.

Why do patients seek a diagnosis?
(I don’t consider these labels as valid diagnoses in the traditional sense of the word, in that they align with a specific pathological process that can be reliably identified). Firstly, it must be understood that many patients have unexplained pain for reasons other than physical pathology. There are myriad social and psychological reasons for patients to complain of pain and other symptoms (such as job dissatisfaction and unpleasantness at home), and the expression of the symptoms often reflects what is expected, what has been seen or heard before, and what is considered socially acceptable. Seeking medical advice is the social norm for anyone with symptoms, and having a diagnosis established has many implications for the patients, apart from validation of their suffering. But giving them a label may not be the answer to their underlying (psychosocial) problem.

Why do doctors give out these labels?
It is virtually inconceivable for doctors to say to a patient “I cannot find an underlying physical cause for your pain. There may be other psychological and social reasons for your symptoms, and I would be happy to explore that with you, but I do not feel that it would be in your best interests to continue to investigate your symptoms, or refer you for any more opinions or treatments”. Instead they get more tests and, worst of all, they get treatments. Injections, TENS machines, physiotherapy, hydrotherapy, opioid analgesics, and the biggest treatment of them all, surgery. I wish it was acceptable for us to say to a patient complaining of back pain that they have a diagnosis of “unexplained back pain that they cannot currently cope with”, rather than a “ruptured disc” or whatever other finding we lift from the MRI report (there is always something on the MRI scan). The former diagnosis would be more accurate, and less harmful than the latter.

The age-old disease-illness paradigm is alive and well.
We should be treating patients with clear, correctible pathology – those that are sick. However, those that are not sick (no disease) but are not well (have symptoms) may be made sick by medical intervention, and they should not be forced into the disease-illness paradigm. Alternative management strategies should be employed for such patients. Often, talking to the patient and reassuring them that they do not have a serious disease and are unlikely to get worse can be enough. More often it is much harder to undo the long process of conditioning that has led to the current complaints.

As the good doctor Knock said: “Well people are sick people who simply don’t know it—yet.” (link)

  1. Fascinating overview here. Thanks for this.

    But as a heart attack survivor, I have mixed feelings about this topic.

    I was sent home from the E.R. with a GERD misdiagnosis - despite presenting with textbook symptoms of crushing chest pain, nausea, sweating and pain radiating down my left arm. Why? Because EKG, troponins, treadmill stress test results were "normal".

    I left the hospital that morning feeling supremely embarrassed for having made a fuss over nothing. Then I proceeded to suffer increasingly debilitating symptoms - but hey! at least I knew it wasn't my heart! A man with the letters M.D. after his name had told me quite clearly after reviewing my "normal" diagnostic test results: "It is NOT your heart!"

    I finally dragged myself back to the E.R. when the symptoms became truly unbearable - this time to a revised diagnosis of "significant heart disease" and emergency treatment for MI.

    So this first E.R. doc's dismissal fits with your description of the ideal: reliance on actual concrete NUMBERS on a test rather than simply hearing the patient's story. Had this E.R. doc Googled my symptoms, he and Dr. Google would have almost immediately come up with the correct diagnosis: MI - not GERD.

    Yet I have personally met other patients since then who are unrealistically convinced that they are indeed having a serious heart attack despite NOT having one - the so-called "cardiophobes" of the world.

    These folks (with symptoms but "normal" cardiac test results) are clogging up E.Rs and making it that much harder for those of us (with symptoms and "normal" cardiac test results) to be taken seriously - until it is too late.

    2. Thank you so much for the recommendation, Dr. S. I suspect our interests overlap considerably. Reading your post, I was reminded of an article by Arthur J. Barsky back in the 1980s called ‘The Paradox of Health.’ Part of his argument was that, due to greater preoccupation with health (what I’ve been calling, following Robert Crawford, ‘healthism’), patients tend to scrutinize themselves more closely for symptoms and – reasonably enough -- tend to find what they’re looking for. And that this accounts for an increase in the “worried well” (does the medical profession still talk about the “worried well” or has that terminology disappeared?). Barsky made a few other good points too, ahead of his time: the increased emphasis on health (as in media coverage) creates apprehension and alarm about disease. And patients have unrealistic expectations of medicine, assuming every symptom can be diagnosed and “cured.”

      I enjoyed this post very much. Excellent observation about how each specialty has its default diagnosis. And I appreciate your identification of the social and psychological origins of unexplained symptoms. Fifty to sixty years ago, when the doctor-patient relationship looked more like the Dr. Marcus Welby ideal, psychosomatic symptoms could be alleviated by a doctor who had the time and patience to listen to, understand, and reassure a patient. (Edward Shorter writes about this in ‘Bedside Manners’). Those days are gone. We live in a time when economic constraints require a different set of behaviors. Fortunately, there are still doctors, even young ones, who resist this change. I would recommend the blog of Dr. Jonathan Tomlinson, if you’re not already familiar with it. For example the post ‘What’s in a name? Patients, clients and consumers’ (http://bit.ly/Htukrr).

      I like your identification of how medicine is driven by “our keenness to see it work.” That’s exactly the type of thing that needs to be pointed out and raised to a level of awareness so that we see it in operation. I look forward to reading your others posts here.

    3. Thanks for your support, and for the references. Yes, I agree with your comments, but as for the Marcus Welby-type of doctor that you mention, I think they still exist but these days they are not taken seriously by patients who are primed to expect high-cost, high-tech, intervention-based solutions and are not even remotely aware of the possibility that psychosocial issues may have a role in their complaints. To explain this concept to patients takes a long time, after which they look at me with a perplexed expression that makes me think: I should have just booked them in for surgery - it would have been easier. This is partly because I get paid to operate, not to talk - a perverse incentive. More on that point in the next post ...

  2. So true. In 1996, my wife was transported to the ER with severe chest pain. She has Marfan Syndrome, which carries the risk of a dissecting aortic aneurysm. Explaining her condition to the ER doc, she asked how he was going to rule out a dissection. The doc said that he was going to run cardiac enzymes. My wife pushed harder for a CT scan and he agreed. Sure enough, the CT scan revealed a dissection and she was sent in for emergency surgery. The ER doctor couldn't see the other possibilities because her symptoms met his normal paradigm.

    More recently, she dealt with SIX YEARS of headaches. She has dural ectasia associated with Marfan Syndrome and headaches that were severe when upright, went away when lying down, and relieved by caffeine dosing. She also had a pleural effusion of unknown origin. Neurology went down the road of migraines, not even entertaining the idea of a spontaneous CSF leak, despite my wife's suggestion. Neurosurgery blamed a Chiari I malformation. A chance cardiology MRI was read by a radiologist, who suggested that there was a potential hole between the dura and the pleural space. A thoracentesis revealed the presence of CSF. Neurosurgery applied a blood patch, resolving the leak and the headaches. Again, both neurology and neurosurgery were stuck in their paradigms of what they commonly see.

    All specialties are susceptible to the tunnel vision of what is common. Our best doctor experiences have involved doctors that are intellectually curious enough to consider the entire complexity of my wife versus trying to treat a symptom that appears common enough in most circumstances.

    In a similar way, I've been successful at addressing some of my own health concerns through nutrition. Gout is traditionally viewed through a lens of high-purine foods as a causative factor. I had no success with that approach and continued to take a daily medication to limit uric acid production, still suffering from occasional gout attacks. I learned that fructose has a byproduct of uric acid when metabolized by the liver, so I decided to try an experiment: instead of taking a medication to limit uric acid production, I eliminated sugar from my diet, changing nothing else. I got off of medication, and I haven't had a gout attack for over a year. I've even reintroduced limited alcohol, a previous severe trigger, with no problems. My doctor was stunned - it didn't fit his paradigm for gout treatment.

    Patients must act as a partner in the healthcare process: researching, suggesting, questioning. And, in many cases, patients must be willing to make significant lifestyle choices/changes (like I did eliminating sugar) in order to help figure things out. Too many patients want the doctor to fix them by passively prescribing medication or performing a potentially unnecessary surgery without changing a thing about how they live.

    1. Thanks Rick,
      I particularly agree with your opinion that patients need to take more control of their own health. Sure, take advice from a doctor; hell, take advice from a few doctors because opinions vary. But you have to put the effort in, weigh up that advice, and then make the decision yourself, and you should be comfortable with that decision.
