What Is Cortisol Dysregulation?
Cortisol dysregulation occurs when the hypothalamic-pituitary-adrenal (HPA) axis malfunctions. Healthy cortisol follows a diurnal rhythm: high in the morning, gradually declining throughout the day, and lowest at night. Dysregulation means this rhythm is flattened, reversed, or erratic.
| Pattern | Description | Common Causes |
|---|---|---|
| High cortisol | Chronically elevated stress hormone | Chronic stress, anxiety, poor sleep, caffeine |
| Low cortisol | Adrenal fatigue or insufficiency | Burnout, long-term stress, autoimmune conditions |
| Flat rhythm | No morning peak or evening drop | Shift work, jet lag, irregular sleep |
| Evening spike | High cortisol at night | Late exercise, blue light, evening stress |
Common Symptoms
- Fatigue, especially morning fatigue or afternoon crashes
- Weight gain, especially abdominal fat
