Here is a quick overview of the hormone cortisol. It is released from the adrenal glands and is involved in the HPA axis (hypothalamus, pituitary, adrenal).
Recent literature has show low cortisol levels to be a biomarker for Long Covid. Low cortisol levels are consistent with feelings of fatigue, weakness, and mood shifts. These are consistent symptoms with Long Covid.
Additional research is necessary in this field to see the full picture. The work we have now are just pieces, but allow us to begin to create stronger hypotheses and rigorous studies to help find relief in the patients suffering.
