Endocrine Disruption

Domain: Endocrine

HPA axis dysfunction, thyroid abnormalities, and hormonal dysregulation in ME/CFS.

What We Know

  • HPA axis hypoactivation has been observed in some ME/CFS studies, with reduced cortisol awakening response. This is opposite to the pattern seen in depression, suggesting a biologically distinct mechanism.

What We Think

  • Cortisol rhythm studies and adrenal imaging are being used alongside immune profiling to understand neuroendocrine-immune interactions.

What We Don't Know

  • Endocrine findings are inconsistent across ME/CFS studies. The clinical significance of mild HPA hypoactivation is unclear. Thyroid abnormalities in ME/CFS are debated.
