What Is Adrenal Fatigue?
Adrenal fatigue is a term used to describe feeling constantly tired, worn out, and unable to handle stress well because your adrenal glands are working overtime and struggling to keep up with hormone production, especially cortisol, which helps manage stress. People living with this often experience low energy, trouble concentrating, cravings, mood changes, and sleep difficulties. While it is not an official medical diagnosis, adrenal fatigue is commonly linked to prolonged physical or emotional stress, poor sleep, and lifestyle factors that strain your body’s ability to cope.

FAQs
Most people describe it as wired but exhausted. You wake up already tired, need coffee to get going, get a second wind late at night, and find stress harder to shake off than it used to be. Cravings for salty or sweet food, brain fog and broken sleep usually sit alongside it.
The pattern is usually described in three phases. An alarm phase, where cortisol runs high and you feel wired and driven. A resistance phase, where the body compensates and your energy dips through the day. An exhaustion phase, where cortisol output is blunted and the tiredness becomes constant. Measuring your cortisol rhythm across a full day is what shows which pattern you are actually in.
We look at your cortisol rhythm rather than one reading. The Cortisol Awakening Response test measures the rise in the first 30 to 60 minutes after waking, which is the window that tells us most. Saliva Adrenal Hormone Testing maps cortisol across the whole day. Both are collected at home.
There is no single fix, and anyone promising one is guessing. Care is built around what your testing actually shows, and usually combines changes to sleep and stress load, nutrition to steady blood sugar through the day, and targeted nutritional or herbal support. Most people work through it over several months rather than a few weeks.
Adrenal fatigue is not a formal medical diagnosis, so a GP will often investigate other causes of ongoing fatigue first, which is worth doing. A naturopath or clinical nutritionist can look at your cortisol pattern, diet, sleep and stress load together, and will refer you back to your GP if anything needs medical review.
