Cortisol

What is cortisol?

Cortisol is a hormone synthesized and secreted by the adrenal glands of the kidneys that plays a major role in regulating stress, metabolism, and immunity. It follows a circadian rhythm that is affected by sleep- naturally rising in the early morning and falling in the evening.


Why is it included in the Balance axis?

High cortisol levels are an indicator of acute (sudden), chronic (long-term), and/or traumatic (life-threatening) stress. Secondary factors associated with mental stress include alcohol drinking, smoking, a lack of exercise, inadequate sleep, and poor nutrition. Over time, prolonged high levels of cortisol (Cushing's disease) can lead to weight gain, fat redistribution, poor sleep, a lowered immune system, and increased inflammation. Low levels might indicate poor adrenal function or Addison's disease.

How can I better understand my results?

Normal cortisol ranges:

  • Peaks in the morning between 6 am - 8 am: 10-20 ug/dL
  • Falls in the evening around 4 pm: 3-10 ug/dL

While levels in the lower range are better for inflammation, morning cortisol levels under 3 ug/dL may indicate adrenal insufficiency, and above 50 ug/dL could indicate Cushing's disease. Keep in mind that certain medications can raise cortisol levels.
