Chronic Fatigue Syndrome (CFS), ME and The T3 Connection

I have always believed that Chronic Fatigue Syndrome (CFS) and ME are a collection of symptoms that are likely to have multiple root causes.

I have held the view for many years that one cause is low T3-effect within the cells.

I was diagnosed with CFS! However, I got well using T3-Only therapy. I wrote about this in my book, Recovering with T3, and early on in the life of this blog.

This interesting article is entitled ‘Pure T3 Thyroid and Stories of Recovery from Chronic Fatigue Syndrome (ME/CFS) and Fibromyalgia: An Overview.’, I think you will find it interesting:

Just to clarify, I would not be stupid enough to suggest that all CFS/ME patients have a low T3 issue. However, I do think some CFS patients do have this issue and could recover with the right treatment.

The symptoms that develop due to low cellular T3-effect are virtually the same as those of  CFS/ME. This low cellular T3-effect is often not visible in thyroid blood tests, as these cannot measure the cellular activity of the T3.

I think that for many CFS/ME patients the connection is definitely relevant. This is not a new position that I am taking – I have held it for 20-30 years!

Clearly, many other issues can cause the symptoms associated with CFS/ME, e.g. low B12 is just one of these.

This is another interesting link, given to me by a thyroid patient. It discusses the link between elevated reverse T3 (rT3) and CFS/ME. Interesting, as rT3 is not even tested in some countries (including the UK):
