Thyroid problems may be a culprit behind unexplained diseases such as ME/CFS and FMS. In most cases, the health problems experienced by these patients are part of a more basic and profound dysfunction, such as primary damage to the hypothalamus or pituitary gland through infection and/or some other insult.
Eminent international researchers have found that the endocrine system in ME/CFS sufferers is disrupted. A key feature is a defect in the hypothalamic-pituitary-adrenal (HPA) axis. In one study, computed tomography (CT) of ME patients showed that both adrenal glands were reduced by as much as 50 per cent compared with the controls.
