Under normal conditions, feeling stressed can be a healthy and helpful bodily reaction, giving us a heightened sense of awareness and the extra energy needed to help us cope with a given situation. However, an extended stressful situation or the constant pressure to perform can sometimes be crippling, overwhelming the nervous system and leading to adrenal exhaustion, especially acute or chronic illnesses. Chronic inflammatory conditions such as inflammatory bowel diseases (Crohn’s, IBS), arthritis (rheumatoid or osteoarthritis), diabetes, weight gain, and many others will put constant demands on cortisol production and eventually exhaust the adrenal stress response system.
Because cortisol levels are a good predictor of the stress response in most individuals, measuring cortisol levels is a common tool to assess what level and type of stress you are experiencing. When cortisol levels are very low, it is a sign of adrenal exhaustion or burnout. When cortisol levels are very high it may mean there is an uncontrolled acute stressor present (chronic inflammation) or that the feedback loops that should be lowering cortisol are not functioning properly.

There are three stages of adrenal exhaustion: early/acute adrenal stress (stage 1), mid-phase adrenal fatigue (stage 2), and late phase (stage 3) adrenal fatigue. Each of these stages affects the body in different ways by creating an imbalance in hormone production, blood sugar handling, disruption of sleep/wake cycles, increased frequency in muscle and joint injuries, and the likelihood of illness in varying degrees.
3 Adrenal Stress Levels
Early/Acute Adrenal Stress
Sometimes called “The Alarm Reaction” or being “wired,” this is a response to current demanding stressful situations that are causing high amounts of cortisol production without adequate feedback reduction. These individuals may lack an adequate diurnal rhythm as well. Acute adrenal stress will eventually suppress important immune functions and will often result in increased risk of sickness.
Mid-Phase Adrenal Fatigue
This condition can be the result of adjustments to an ongoing acute adrenal stress condition or the accumulation of years of mild stress without adequate relaxation and recuperation. These individuals may have cortisol levels within the normal range but either lacks proper circadian rhythm or have reduced levels of DHEA.
Late Phase Adrenal Fatigue
This is often called “burnout” or adrenal exhaustion. This condition typically has low or very low cortisol levels (Addison’s disease is the complete loss of cortisol production). These individuals are easily overwhelmed by any stress and find that even simple tasks become burdensome.
Through a process of physical examination, health history, lifestyle assessment and functional testing, Dr. Jeff Ulery can find out what level of stress or fatigue you are currently experiencing and develop recommendations so you can experience renewal and a healthy, balanced, more fulfilling life!
