- Higher urinary cortisol levels have been found in BPD patients compared to controls.
- When BPD patients were divided according to the presence of high or low number of PTSD symptoms, high cortisol levels were found only in BPD patients with a low number of PTSD symptoms.
- Found an exaggerated ACTH and cortisol response during the DEX/CRH test in the blood of BPD female subjects who had experienced childhood abuse.

The Hypothalamic-Pituitary-Adrenal (HPA) axis is a crucial neuroendocrine system that orchestrates the body's response to stress. While highly active during a stress response, its hormonal cascade operates more slowly than the immediate reaction of the sympathetic nervous system. The process begins when the hypothalamus releases corticotropin-releasing factor (CRF), which signals the pituitary gland to secrete adrenocorticotropic hormone (ACTH). ACTH then travels to the adrenal glands, stimulating them to release hormones like cortisol into the bloodstream. This hormonal sequence ultimately provides the body with the energy needed to manage the stressor.

HPA Axis in BPD

Comfort eating is eating as a way to soothe negative emotions. Research showed that eating sweet high-fat food can blunt the activity in the hypothalamic-pituitary-adrenal axis (HPA), a neuroendocrine system that in humans has been shown to regulate psychological processes, including negative emotions.

Response to prolonged periods of psychological stress (that can lead to poor mental health) involving the endocrine system and its release of corticosteroids, which increases over time as a result of this.

Chronic Stress is the result in an Overactivation of the HPA-axis

Cortisol is a stress hormone. During the beginning of an exposure to a stressor, it provides the body with energy. However, long periods of exposure to stressors leads to sustained levels of cortisol, which in turn weakens the immune system.

The Hypothalamic-Pituitary-Adrenal (HPA) axis is visually represented by showing the locations of its key components within the human body. The hypothalamus and pituitary gland are located within the brain, while the adrenal glands are situated on top of the kidneys. Arrows are used to depict the flow of hormonal signals, starting from the hypothalamus, moving to the pituitary gland, and finally reaching the adrenal glands.

Anatomical Representation of the HPA Axis

Research has long indicated that individuals with depression often exhibit abnormal levels of cortisol, a key stress hormone released by the neuroendocrine system during the body's fight-or-flight response. Elevated cortisol is particularly prevalent in depressed individuals who have experienced early life trauma, such as childhood abuse or the loss of a parent.
