Part 5: Mitochondrial Failure – Two Stages of Fatigue In ME/CFS

1 Comment

I hope everyone has enjoyed reading this series over the past week on mitochondrial failure and dysfunction.  It’s always so amazing to me how complex an illness like ME/CFS is and that researchers are making such great progress trying to get to the bottom of it.

Dr. Myhill and ME/CFS researchers believe that a person’s severity of their CFS is reflective of how severe their mitochondrial dysfunction/failure is.  According to Dr. Myhill, there are two “clear stages” of fatigue:

  • Mild Chronic Fatigue Syndrome

For someone who has mild case of chronic fatigue syndrome, there is mild failure of the mitochondria.  Dr. Myhill says the body becomes less efficient because when the mitochondria goes slow, the cells go slow.  In turn, when the cells go slow the organs go slow.  Dr. Myhill explains an example of this very well:

Somebody mildly affected would not be able to increase their fitness – if they try to exercise they would quickly switch into lactic acid metabolism and would be forced to stop. Indeed we now know that mitochondria are responsible for controlling the normal ageing process. Therefore many of the symptoms and diseases associated with ageing are actually the result of mitochondrial function declining. Indeed many of these ageing diseases have now been attributed to mitochondrial failure such as loss of tissues (loss of muscle bulk), organ failures, neurodegenerative conditions, heart disease and cancer. Many symptoms which are attributed to ageing are due to mitochondria. It is not that we can stop the mitochondria from ageing, but we can certainly slow it all down using good nutrition, good diet, freedom from toxic stress, healthy lifestyles and so on.

  • Severe Chronic Fatigue Syndrome

In severe chronic fatigue syndrome, these people have the same issues as those with the mild form plus they also have another problem that involves the heart. Dr. Myhill says the heart will go into a low output stage because the mitochondria can’t supply the heart with sufficient energy. The heart is the most metabolically demanding organ in the body. This low output stage compounds the problem of all mitochondria.

If the heart is in a low output state then blood supply is poor and therefore the fuel and oxygen necessary for the engine to work are also impaired. So this compounds all the above problems and makes them proceed even more quickly and people end up with greater disability.

Dr. Myhill believes it is a combination of the poor mitochondrial function and this can become a critical problem when it comes to cardiac output, “which precipitates a much more severe illness in someone who is already compromised.”

      Thank you for posting this extremely important aspect of ME/CFS. However, I wonder why Dr. Mayhill claims all the credit in her findings, while ME/CFS is a Mitochodrial Disease has been well explained, point by point, from one of Dr. Paul Chaney’s lectures in as far back as 2006, as I recall (I could be wrong on the time frame).

      Sincerely,
      Jax
