Sounds like a dream, but when we hit 30’s our body starts responding differently to constant daily stress factors. At the end of the day, we end up with endless checkups which cannot find the root of the problem and only work on covering up the symptoms. In reality, things work out much simpler.

Stress, frustration, brain fog, anxiety, chronic fatigue, low immune system. Those and more symptoms are very often staying undiagnosed by medicine. The root of the problem is in most of the cases simpler than it seems and in most of the cases can be managed and also reversed for good.

HPA (Hypothalamic-Pituitary-Adrenal) Axis

Pituitary Gland:

The pituitary gland is essential for cortisol transmission by secreting adrenocorticotropic hormone (ACTH), which stimulates cortisol production in the adrenal glands. This process is part of the hypothalamus-pituitary-adrenal (HPA) axis, starting with the hypothalamus releasing corticotropin-releasing hormone (CRH). Elevated cortisol levels provide negative feedback to the pituitary and hypothalamus, stopping further release.

• Signal Reception from the Hypothalamus: When there is a need for cortisol, such as during periods of stress or low blood levels, the hypothalamus identifies this requirement and releases corticotropin-releasing hormone (CRH).
• Stimulates the Pituitary Gland: CRH moves to the anterior pituitary, prompting it to release adrenocorticotropic hormone (ACTH) in response.
• Regulates the Adrenal Gland: ACTH moves through the bloodstream to reach the adrenal glands, which are situated atop the kidneys.
• Stimulates Cortisol Production: ACTH prompts the adrenal cortex (the outer section of the adrenal gland) to produce and release cortisol.

Thyroid Gland:

The thyroid gland and cortisol systems are interconnected, with thyroid hormones affecting cortisol metabolism and vice versa. High cortisol can suppress TSH and hinder the conversion of T4 to T3, while low thyroid function can elevate cortisol. This complex feedback loop impacts metabolism, energy, and stress response, with both systems influencing each other’s activity.

• Chronic stress raises cortisol levels, which can suppress TSH release from the pituitary gland and slow thyroid function.
• Elevated cortisol levels impair the conversion of T4 (inactive) to T3 (active), leading to symptoms of cellular hypothyroidism.
• Elevated cortisol levels create a feedback mechanism that suppresses TSH, resulting in a complex loop.
• Thyroid hormones, particularly T3, can enhance metabolism and aid in cortisol breakdown, suggesting that hyperthyroidism may increase cortisol turnover.
• Thyroid hormones like T3 can directly stimulate cortisol secretion from adrenal cells, sometimes in conjunction with adrenocorticotropic hormone (ACTH).

Adrenal Gland:

The adrenal gland, specifically the adrenal cortex, is key in cortisol production, triggered by signals from the pituitary gland (ACTH) and hypothalamus (CRH) via the HPA axis. It acts as the body’s “stress factory,” generating cortisol to boost energy, regulate metabolism, and manage inflammation, converting stress signals into physical responses.

• HPA Axis, the Signal: When under stress, the hypothalamus secretes CRH (Corticotropin-Releasing Hormone). Corticotropin-Releasing Hormone (CRH) signals the pituitary gland to secrete Adrenocorticotropic Hormone (ACTH).
• Adrenal Gland Activation: ACTH moves through the bloodstream to reach the adrenal glands, where it specifically stimulates the adrenal cortex.
• Cortisol Production & Release: The adrenal cortex produces and secretes cortisol directly into the bloodstream.
• Feedback Loop: Once cortisol levels reach an adequate level, they send a signal back to the hypothalamus and pituitary gland to halt the production of CRH and ACTH, effectively shutting down the stress response through a process known as negative feedback.

In essence, the adrenal gland serves as the effector organ, converting the brain’s stress signal (through ACTH) into the extensive effects of cortisol throughout the body.

Vagus Nerve:

The vagus nerve plays a crucial role in managing the stress response by regulating cortisol release through its interaction with the Hypothalamic-Pituitary-Adrenal (HPA) axis. It can activate the axis via signals from organs like the gut, leading to cortisol release, or inhibit it through efferent signals, particularly acetylcholine. A high vagal tone is linked to lower cortisol levels, while a low tone, often seen in stress or depression, can lead to dysregulated cortisol levels.

The vagus nerve functions as a bidirectional highway, transmitting stress signals to the brain, which triggers cortisol release, while also sending calming signals that help inhibit inflammation and excess cortisol. Its activity is essential for preserving the balance between the nervous and endocrine systems in times of stress.

Chronic stress can affect our life quality, especially after age of 30. it is essential to have a proper cleanse, it does take time, but our body needs to recover what was caused by a long period of time, in such cases years.
