Understanding Thyroid and Adrenal Function in Health & Fitness
TLDR Learn about the regulation and function of thyroid hormones, the complexities of the adrenal system, and the importance of addressing underlying health conditions for optimal adrenal function. Explore different formulations of T3 for treating hypothyroidism and the nuances of hormone replacement therapy for both men and women.
Timestamped Summary
00:00
The episode explores the regulation and function of thyroid hormones, emphasizing the conversion of inactive T4 to active T3 through diodinases.
05:02
D1 and D2 convert T4 into the active hormone T3, while D3 produces reverse T3, which can block the effects of T3 and is often elevated in response to inflammation or nutrient scarcity.
10:26
Different formulations of T3, such as compounded control release T3 and desiccated thyroid, are used to treat hypothyroidism, with varying opinions on their effectiveness among patients.
15:11
The adrenal system is complex and difficult to assess through blood tests, requiring saliva or urine tests like the Dutch test to measure free cortisol and cortisol metabolites for a more accurate understanding of adrenal function.
20:11
Factors like inflammation, obesity, and other health issues can impact the conversion of cortisol to cortisone, emphasizing the importance of addressing underlying health conditions for optimal adrenal function.
24:48
Understanding adrenal function involves looking beyond total cortisol levels, considering free cortisol and cortisone, metabolites, and the balance between cortisol and cortisone, highlighting the complexity of the system and the importance of addressing underlying issues rather than resorting to glucocorticoid replacement therapy.
29:18
The menstrual cycle involves fluctuations in hormones like FSH, estrogen, LH, and progesterone, with rising FSH levels signaling menopause and progesterone withdrawal potentially contributing to PMS symptoms.
33:58
Progesterone supplementation can help alleviate symptoms during the luteal phase of the menstrual cycle, with options including a seven-day regimen or continuous use, while testosterone levels in women remain relatively stable throughout the cycle.
39:02
Female sex hormones are more complex than male hormones, with FSH levels at day 345 indicating perimenopause, leading to discussions about hormone replacement therapy, while the male sex hormone system involves testosterone production by the testes, with free testosterone affected by enzymes like five-alpha reductase and aromatase.
43:48
Testosterone replacement therapy is more complex than just looking at total testosterone levels, as free testosterone is the biologically active form that affects symptoms such as low libido, erectile dysfunction, low mood, difficulty putting on muscle mass, and insulin resistance.
48:56
Testosterone replacement therapy should be carefully considered based on both biochemical and symptomatic criteria to ensure effectiveness and minimize potential side effects.
53:48
Understanding the male sex hormone system involves nuances in diagnosis and treatment that should be carefully considered.
