Chronic Fatigue Syndrome Causes

In writing this article on Chronic Fatigue Syndrome causes, I wish to state that I am not a medical practitioner. I am simply someone who has lived with CFS/ME for 23 years. 'Simply' doesn't seem quite the right word!

I hope this CFS article will help you give some ideas on how to answer when someone asks you the question: What is the cause of Chronic Fatigue Syndrome?

how many have illness CFS

Possible Chronic Fatigue Syndrome causes

Chronic Fatigue Syndrome causes are not known at this time. The suggestion I hear the most is that a virus is responsible.

In the following paragraphs I put forward four commonly suggested causes of CFS. I repeat again that I am not a medical expert.

Epstein Barr Virus

The Epstein Barr Virus (EBV) causes Infectious Mononucleosis. This is often referred to in the USA as the illness Mono and in the UK as Glandular Fever.

Epstein Barr Virus has been put forward as a possible CFS cause as many people develop CFS following an outbreak of EBV. Yet many patients have not had EBV.

Magnesium deficiency

Magnesium deficiency is common in those with CFS. It is likely that magnesium deficiency is not a CFS cause so much as a result of whatever is happening within the body to cause the illness.

For myself, I consistently tested for low magnesium throughout the years of severe illness. I suspect I would continue to do so, though I no longer pay to have the test done.

The blood test you need for low magnesium is the red blood cell magnesium test.

If you are in the UK, the test for magnesium is not the one available on the NHS which will often show up as normal. The blood testing clinic I used was Biolab in London, UK. With your GP's agreement, it is possible to have blood samples collected and sent there for testing.

Mitochondrial Dysfunction in CFS

Dr Sarah Myhill, UK, published a paper in 2009, showing that many patients with M.E. have mitochondrial dysfunction.

In 2014 the Optimum Health Clinic in London, UK funded research into mitochondrial function.

Emotional Trauma

Emotional trauma is a factor that precedes the occurrence of much chronic illness. In the case of cancer, for example, studies have suggested a correlation between emotional trauma and the subsequent onset of cancer within the following six months.

I don't consider that I had suffered any particular trauma at the time of becoming very ill, although certainly there had been stressful events in preceding years.

After I got ill – and  in my experience it is the same for many people – I had to deal with far greater emotional trauma than prior to illness. Chronic illness had repercussions on my finances, relationships, housing and survival.

I believe that those of us living with CFS increase our quality of life and chances of recovery by working with emotional healing therapy such as EFT and self talk. We can hope to let go of negative events in the past. AND, just importantly, we can learn to cope with the ongoing emotional challenge of living with chronic illness.

Having said that, it is important, when living with ME or CFS to accept that you are living with a physical illness so that you can take appropriate steps to manage and limit the illness.

Despite emotional trauma experienced during 14 years of being bedbound, please note, I still experienced dramatic healing.

I say this because sometimes when we are living with chronic illness and pursuing alternative healing therapy, we can think we need to become sorted out emotionally before we can heal.
Look around you. There are many people suffering with painful emotional trauma who are walking around in good physical health!

The Medical History Profile of People With CFS/ME. Subgroups - What Is My Subgroup?

  • Viral infections
  • Allergies
  • General anaesthetic
  • Vaccinations
  • Multiple Chemical Sensitivity (MCS)
  • Reaction to dental amalgams, leading to raised levels of mercury.
  • Working too hard
  • Lyme Disease
  • Following an accident or other potentially traumatic event

A CFS cause is not known at this time. However, certain subgroups have been identified among those who receive a diagnosis of CFS.

Visitors to this alternative healing website are often interested in my own journey with CFS/ME.
Below I discuss how well these subgroups fit with my own medical history.

In terms of identifying Chronic Fatigue Syndrome causes, the subgroups  provide hints but no more.
Myself, along with many others, fit into many different sub-groups.
There is no way to know if Chronic Fatigue Syndrome causes are multiple and cumulative or if one single factor is responsible.

Myalgic Encephalomyelitis / CFS  and viral infections

Early on when living with illness I had no diagnosis. As some of you will know, it is hard to be very ill and have no label to give to others to explain why you are no longer your previously healthy self.

12 months later I had blood tests which showed the presence of an ongoing viral infection.

6 months after that, I was diagnosed with Myalgic Encephalomyelitis.

If someone receives a blood test early on after CFS symptoms develop, the tests sometimes reveal an infection with an enterovirus or influenza.
Some cases of CFS follow mononucleosis (glandular fever) or hepatitis A.
However, by the time most people are given a diagnosis of Chronic Fatigue Syndrome there is no longer any evidence of viral infection.

I know of one lady who contracted M.E. at University. A number of her fellow students got a virus. Many recovered but 8 of them went on to develop the illness ME.
(It is interesting to note that because they were clear on the cause and had each other's experience as reference, they did not have any of the emotional trauma of disbelief that many with the diagnosis of ME unfortunately have to deal with.
This lady rested well for a number of years and, despite having been in a wheelchair, made a full recovery. Her experience suggests that Chronic Fatigue Syndrome causes may be multiple - a virus combined with susceptibility due to other factors.)

Myalgic Encephalomyelitis / CFS and allergies

I had a history of childhood allergies, with the symptoms being catarrh and stomach problems. They were not disabling.

Myalgic Encephalomyelitis / CFS and general anaesthetic

In 1990 I had an operation to reduce swelling in my nose. It was as though I never quite fully came around after the general anaesthetic. Many years later I discovered I had Multiple Chemical Sensitivity (MCS) - see more below. It is likely that the anaesthetic played a role in my deteriorating health.

Myalgic Encephalomyelitis / CFS and vaccines

Although I got CFS at the age of 23, I already had some history of foreign travel to places that required vaccinations -- I had been to Israel, Egypt and Hong Kong.

I also remember reacting quite badly to the BCG vaccination at school after which my perspiration was embarrassingly yellow in colour. Looking back, this wasn't normal.

Myalgic Encephalomyelitis / CFS and Multiple Chemical Sensitivity (MCS)

After many years of illness with ME /CFS I realised in 2000 that I had Multiple Chemical Sensitivity (MCS).

On reducing the chemical load in my environment my quality of life improved significantly. I was able to sit up more easily to be fed a meal and regained some speech.

On looking back over my life, I realise I had had MCS all along.

Age 5 my parent's built a loft conversion in their house and this became my bedroom.
Back in 1974 the rules were less strict about levels of toxins in building materials. It is probable that there was lead in the paint and other toxins in the floorboards.

From the time I slept in this room, age 5, I had dull aches in my legs with jumpiness at night - often called 'restless legs'.
I remember hearing the cuckoo clock ring each hour reminding me that I was still awake. (Mind you, it seems unbelievable now to sleep in a room with a cuckoo clock!)

In more recent years, I realised that an increase in the severity of ME / CFS had followed a time when a carer had washed my sheets in fabric conditioner.

One doctor felt that MCS was the cause of Chronic Fatigue Syndrome symptoms in my case.

Another doctor thought that MCS was a symptom of CFS in my case.

Myalgic Encephalomyelitis CFS and mercury toxicity

Symptoms of mercury toxicity

"Early signs of mercury toxicity include:

  • decreased sense of touch, hearing, vision and taste,
  • metallic taste in the mouth,
  • fatigue or lack of physical endurance,
  • increased salivation.

More progressed symptoms of mercury toxicity include:

anxiety, depression, anorexia, numbness and parestesias, headaches, hypertension, irritability and excitability, and immune suppression, possibly immune dysregulation.

Advanced disease processes from mercury toxicity include:
tremors and incoordination, anemia, psychoses, manic behaviours, possibly autoimmune disorders, renal dysfunction or failure."

My own exposure to mercury as a possible cause of CFS symptoms

Age 7 I had 8 dental mercury amalgams put into my mouth over two days.

They weren't for decay but for 'sticky fissures'. (At the time I thought they were called sticky fishers!)

With heinsight there may have been a connection between this event and severe stomach problems over the following years, with ongoing and painfully bad indigestion which has only disappeared in recent years.

About age 11, I then developed bad sinusitis which was again ongoing.

I put all such symptoms in the category of 'something to live with' and got on with it. It was only when looking for Chronic Fatigue Syndrome causes and answering questions posed by alternative healing practitioners that these past events took on a new possible significance.

In addition mercury is an ingredient in many vaccines in the form of thimerosol.

In 2002, I had a fecal test for mercury levels. My levels were off the chart.

At the time I was bedbound and there were few possibilities for treatment.

As a result of writing this article I now feel even more strongly that mercury toxicity should be included in investigating possible Chronic Fatigue Syndrome causes.

Research into mercury toxicity

  • "Based on recent epidemiological findings, it can be claimed that the safety of mercury released from dental amalgam fillings is questionable."
    Click through to read research results on the adverse effects of mercury amalgams.
  • 2008 April. A study showed that mercury is released from dental amalgam fillings when individuals use their mobile phones or undergo MRI scans.
  • 2014 April. A further study assessed and confirmed that high-field MRI scans increase the mercury release from dental amalgam fillings.

ME / CFS and working too hard

I worked hard and played hard. I remember a time when I had a very nasty virus which put me in bed for a day. It took a lot to make me go to bed. I then decided that I just had to do what was planned and got out and acted as though I was fine.

I had a great capacity to push through symptoms, which I believe is shared by many people living with ME or CFS. (For recovery or management it is SO important to learn to 'give in' to the illness and listen to your body.)

ME and CFS are often experienced in isolation but occasionally there have been outbreaks. One of the first was in 1955 at the Royal Free Hospital, Hampstead, UK where the hospital had to be shut down as so many doctors and nurses became ill with a polio type illness. Some never recovered.

The illness is common among the medical community, leading some people to suggest that exposure to viruses combined with pushing through symptoms to continue working leads to the illness taking hold.

ME / CFS and Lyme Disease

In 1990, after camping in a barn, I found a tick buried into me. (It was later in 1990 that I had the operation mentioned above.) I had pulled the tick off. Apparently, when you do so, the dying tick injects something into your system.

In 1987 I had worked on summer camp in Massachusetts in a wood by a lake - this is another possible occasion where I could have been bitten by a tick.

Years after I became ill, something small and dark worked its way up to the surface of my skin. Quite possibly a tick had been successfully living in me for all those years.

Lyme disease is another candidate among possible causes of Chronic Fatigue Syndrome.

Reduced symptoms from drugs for other conditions
may indicate Chronic Fatigue Syndrome causes

At least two drugs have led to alleviation of Chronic Fatigue Syndrome symptoms and therefore provide possible clues to Chronic Fatigue Syndrome causes.

The need for a diagnostic marker for CFS

What is a diagnostic marker?

If there was a clear diagnostic marker or biomarker, you could go to your doctor, have a test and you would be given a diagnosis of Myalgic Encephalomyelitis or CFS as a result. 

The use of the name 'syndrome' as in Chronic Fatigue Syndrome is a result of the absence of a diagnostic marker. A syndrome is determined instead by a collection of symptoms.

Consistent abnormalities of brainstem and cortical perfusion have been demonstrated in adult patients with Myalgic Encephalomyelitis using PET scans. Unfortunately PET scans are expensive and not widely available, or they would constitute a possible diagnostic marker. (Research by Work by Costa in London, UK)

With a clear diagnostic marker researchers could be sure that they were studying a group of people with the same illness and Chronic Fatigue Syndrome causes could be more easily identified.
