Stress Axis Dysfunction · “Adrenal Fatigue” · PNI Seville

High cortisol, low cortisol, inverted cortisol: when the stress rhythm breaks.

How the HPA Axis Gets Disrupted

The hypothalamic-pituitary-adrenal axis regulates cortisol with a precise circadian rhythm. When stress is chronic (work, family, illness, poor sleep, young children, constant demands), that rhythm becomes disordered: elevated cortisol at night and low cortisol in the morning. And from there, everything else falls apart.

Symptoms We See in Consultation

You wake up exhausted even if you’ve slept 8 hours. You wake up at 3-4 AM with a racing mind. You need caffeine to get started but it makes you jittery. Cravings for sugar or salt in the afternoon. Low immunity, irregular cycles. Brain fog. Underlying anxiety. “I’m not myself.”

How We Approach It

Salivary cortisol mapping if appropriate. Morning and evening routines that re-anchor the rhythm. Glycemic stabilization (key to avoid adding cortisol spikes). Vagus nerve regulation strategies. Adapted movement (do not add intense training to an exhausted axis). When indicated, adaptogens used judiciously.
