Detailed Information

Cortisol levels should be at their highest level 30 minutes after waking up in the morning, decreasing gradually over the course of the day, reaching their lowest point at bedtime. The resulting curve or pattern allows health care providers to pinpoint issues with adrenal gland function. Alterations in this pattern can results in symptoms related to stress, fatigue and insomnia.
