A Beginner’s Guide to Adrenal Fatigue Syndrome If you find yourself feeling tired no matter how much you sleep, or have a foggy head that just doesn’t seem to lift, it might be caused by Adrenal Fatigue Syndrome (AFS). Life today’s fast-paced and stressful, and lots of people experience ongoing fatigue that they can’t explain. Many doctors dismiss this as part of the modern lifestyle, but this isn’t always the case. Believing otherwise can prolong your experience of AFS symptoms and have a debilitating and worsening effect on your health and on your quality of life. Which is why, if you think you might have AFS, you need to understand more about the disorder and see a doctor who’s aware of it and can test for it.
STRESS AND ADRENAL FATIGUE Your body has a system that activates when you’re under stress. This is called the neuroendometabolic (NEM) stress response, which acts to make changes in your body that allow you to deal with stress. The NEM stress response is designed to cope with short-term periods of stress, such as life or death situations. One of the key strategies that the NEM stress response system uses to deal with stress is to increase cortisol levels in the body. Cortisol is a hormone that’s excreted by your adrenal glands and it performs a number of functions in the body. It helps to stabilize blood sugar levels, reduce inflammation, and has a role in memory formation. It also governs alertness, making you feel wide awake and ready to handle whatever challenge is in front of you. When you’re stressed, your body produces more cortisol to help you cope. Over time, cortisol levels reach their maximum levels and then drop because the adrenal glands are no longer able to keep up with the ongoing demand for cortisol. This result in adrenal fatigue and debilitating symptoms that worsen over time.
