What Does It Mean?
Posterior Pituitary Dysfunction occurs when the pituitary gland fails to regulate hormone production properly, leading to disruptions in adrenal, kidney, and metabolic functions. This dysfunction can result in imbalanced stress response, fluid retention abnormalities, and impaired energy metabolism, affecting multiple bodily systems.
How Did We Get There?
Root Causes:
- Hypothalamic-Pituitary Axis Dysfunction – Impaired signaling disrupts hormonal balance.
- Chronic Stress & Adrenal Fatigue – Dysregulated cortisol production impacts pituitary function.
- Electrolyte & Hydration Imbalances – Altered kidney function affects water and sodium retention.
- Autoimmune & Inflammatory Factors – Systemic inflammation may contribute to pituitary impairment.
- Toxin Exposure & Heavy Metals – Environmental toxins disrupt endocrine function.
Signs & Symptoms:
- Fatigue and reduced stress tolerance
- Increased thirst and frequent urination
- Muscle weakness due to electrolyte imbalances
- Unexplained weight fluctuations
- Cognitive impairment, including brain fog and poor focus
