Study Notes

Adrenal Pathway

Adrenal cortex has three zones: zona glomerulosa (produces aldosterone), zona fasciculata (produces glucocorticoids like cortisol), and zona reticularis (produces androgens).
Cholesterol is crucial for hormone synthesis; both derived from diet and synthesized in the adrenal cortex.
Hormonal progression involves converting cholesterol to pregnenolone, leading to various hormones including cortisol and androgens.
Dihydrotestosterone (DHT) is a testosterone metabolite linked to various health issues in both men and women, including hair loss and metabolic syndrome.
Adrenal fatigue is considered a pseudoscience, with conflicting studies and no consensus among endocrinologists; identified as a myth.
Key nutritional support for adrenal health includes Vitamin C, B5, B6, zinc, and magnesium.

Thyroid Pathway

The relationship between adrenal and thyroid function is essential; adrenal health supports thyroid metabolism.
Decreased adrenal function commonly results in long-term hypothyroidism, necessitating concurrent treatment of both glands.
Thyroid lab tests include TSH, Free T4, Free T3, Reverse T3, and several antibodies (TPO-Ab, Tg-Ab, etc.)
Cortisol affects numerous bodily functions, including glucose regulation, metabolism, immune response, and fetal development.

Adrenal Insufficiency

Addison's disease, a primary cause of adrenal insufficiency, is characterized by a deficiency in cortisol and aldosterone.
Symptoms include fatigue, low blood pressure, abdominal pain, and skin pigmentation changes. Autoimmune factors play a significant role in the disease.
It is often caused by adrenal cortex destruction due to autoimmune processes, infections, or hemorrhages.
Risks of adrenal insufficiency can impact other organs, including the thyroid and pancreas.

Key Health Implications

Hormonal imbalances from either gland can contribute to conditions like infertility, metabolic syndrome, and other systemic health issues.
Evaluation of DHEA levels can provide insight into hormonal health and associated risks in both genders, particularly concerning fertility and cancer.

Conclusion

Both adrenal and thyroid functions are crucial in maintaining overall metabolic health.
Regular assessment of hormone levels and proper nutritional support can aid in optimal gland function and prevent complications.
