Cortisol is the major adrenal steroid hormone and is controlled by the pituitary gland and the hypothalamus. The body’s stress response increases Cortisol in order to mobilize energy to manage and resolve the stressor.
Chronic stress can fatigue the adrenal gland, disrupting its normal diurnal control over Cortisol. This disruption results in symptoms like fatigue, weight gain, insomnia, depression and anxiety.
So if you’re feeling tired and stressed out, check your Cortisol level. Life Extension® offers this test at a significant discount compared to many commercial laboratories.
Since cortisol levels normally fluctuate throughout the day, a blood level is checked in the morning around 8 a.m. and again in the afternoon around 4 p.m. Typically cortisol is highest in the morning and drops during the day for most people. Some people have a “reverse” cortisol curve where it is higher at night instead of being highest in the morning. Obtaining a morning and late afternoon cortisol value provides more information regarding an individual’s daily fluctuation in cortisol. Also, in conjunction with DHEA-S the Cortisol test allows your doctor the opportunity to better evaluate overall adrenal function.
Fasting is not required. Take all medications as prescribed. Do not take your supplements the morning of the test.
