Researchers used a special hormone test (CRH challenge test) to study a group of young women with chronic fatigue who had unusual patterns in their stress hormone system. They found that these patients had a mild form of adrenal insufficiency—their bodies weren't producing quite enough cortisol—but giving them cortisol supplements only helped some of them feel less fatigued. This suggests that their fatigue might involve more than just low cortisol levels.
