Generally speaking, these are disorders which have a statistical relationship to fibromyalgia in that if a patient suffers from one of them then there is a greater probability that they will have fibromyalgia as well. This list is a product of literature reviews. It turned out to be surprisingly long. This fact suggests that we are dealing with some broad phenomenon with wide applicability to many disorders.
Many co-morbidities are central sensitization syndromes and feature over-reactivity to stimuli, and therefore seem to be part of the same disease process as fibromyalgia. Examples are migraine (light and sound oversensitivity), TMJ (tender head and face muscles) and IBS (over-reactive bowel). (These could be considered part a greater fibromyalgia syndrome.)
Other co-morbidities are less likely to be part of the disease process such as SLE, rheumatoid arthritis, osteoarthritis and Sjogren’s syndrome.
The author recommends that clinicians use it as a checklist, starting with asking patients if they have ever been diagnosed with any of them. However, they may still have many of them even if they were never diagnosed. This means that the patient needs a complete functional enquiry such as those found in standard general medical history forms. The physician should study the results of this enquiry with an eye to determine if positive findings are indicative of any fibromyalgia co-morbidities. (For example, if a fibromyalgia patient indicates on their functional enquiry that they have urinary symptoms, then the physician may suspect co-morbid interstitial cystitis.) In very complicated fibromyalgia patients with multiple co-morbidities, this process can be immensely complicated, time consuming and expensive, especially if multiple follow up tests are ordered. There is a need to keep the eye on the ball and to try to work at key underlying issues such as correcting sleep disturbances and psychological contributors to the syndrome. There is a danger that all the doctor’s time and energy is diverted into a massive investigation of symptoms without getting at underlying primary driving issues.

These are unproven co-morbidities that are suspected by the author based on an uncontrolled study.
- Rare immunological diseases (based on the high number of referrals from a tertiary care center to the author’s fibromyalgia clinic) (Further study is needed of the possible role of natural killer cells in such cases.)
- Male and female homosexuals (based on numbers of referrals to author’s fibromyalgia clinic)
- New immigrants to developed countries arriving from unstable counties. For example, there were more than the expected numbers of newly immigrated gypsies to Canada being referred to the author’s fibromyalgia clinic. Immigration can be very stressful. Most cases seen to day involved patients that were having major problems adjusting to a new life in a more developed county. Some had been gainful employed and respected in their country of origin, but became unemployed or had to accept jobs that they considered to be beneath them in Canada. Language barriers and difficult getting a good job made some of the newcomers disillusioned and they suffered identity problems due to erosion of self-respect.
These are controversial because of conflicting reports.
- Pro: Crohn’s disease (Buskila, 1999 said 49% FM in pts with CD) [This seems very high.]
- Pro: ulcerative colitis (Buskila, 1999) said 19% FM in patients with UC
- Con: Crohn’s (Palm, 2001)
- Con: ulcerative colitis (Palm, 2001)
Partial alphabetical bibliography of articles establishing various diseases as being fibromyalgia co-morbidities
This list is presented here in support of the items listed under the main heading “Fibromyalgia Co-morbidities”. There are many other references in the literature that could have been added, but the point was that for each item there should be at least one reference here to support its inclusion.
The list of co-morbidities is very useful if it is converted into a checklist and presented to patients that might have fibromyalgia. However, most patients will not be familiar with all the medical terms in it, and so the list needs to be transformed into simple questions or symptom checklist items. The subheadings on the list such as “neurological” can make results quicker and easier to interpret for the doctor, and so some extent the patient.
