People who suffer from chronic fatigue syndrome (CFS) experience ongoing, debilitating fatigue.

#Unit 7. System Physiology – Animal
  1. A disruption to thyroid hormone production likely results in decreased cortisol in the saliva.
  2. Cortisol is lower in CFS patients because they were just woken up.
  3. The normal elevation in adrenocorticotropic hormone level in waking people is reduced in CFS patients.
