The Myth of Adrenal Fatigue: Understanding Chronic Stress from a GP Perspective

In recent years, the term "adrenal fatigue" has gained traction, suggesting that chronic stress exhausts the adrenal glands, leading to symptoms like persistent tiredness, sleep disturbances, and cravings for salty or sweet foods. However, it's important to understand that adrenal fatigue is not a recognised medical diagnosis within the Australian healthcare system or globally. The Endocrine Society and other reputable medical organisations have found no scientific evidence supporting the existence of this condition.

This doesn’t diminish the reality of the symptoms people experience. Chronic stress can profoundly impact our bodies, leading to what some healthcare professionals refer to as exhaustion disorder or clinical burnout. These terms describe a state of physical and mental exhaustion due to prolonged stress, without attributing it to adrenal gland dysfunction.

Common Symptoms of Chronic Stress and Burnout:

• Persistent fatigue despite rest

• Sleep disturbances (insomnia or unrestful sleep)

• Brain fog and difficulty concentrating

• Increased anxiety or low mood

• Frequent headaches or muscle aches

• Low blood pressure or dizziness

• Cravings for salty or sugary foods

• Unexplained digestive issues

• Feeling overwhelmed or emotionally drained

From a general practice perspective in Australia, rather than focusing on unproven adrenal insufficiency, GPs aim to identify underlying causes such as sleep disorders, thyroid imbalances, iron deficiencies, or mental health conditions like anxiety and depression. Addressing these root issues often leads to effective symptom relief.

For those experiencing these distressing symptoms, consulting a healthcare professional ensures a thorough assessment, proper diagnosis, and an evidence-based management plan to support long-term health and well-being.
