Episode notes
Comprehensive Thyroid Evaluation
- Don't rely solely on TSH for thyroid assessment; consider free T4, T3, and reverse T3.
- Treat hypothyroidism based on symptoms, using T4, T3, or desiccated thyroid as needed.
Cortisol Testing
- Blood tests for total cortisol are unhelpful for assessing adrenal function.
- Free cortisol, measured via saliva or urine, is the biologically active form.
Managing Adrenal Issues
- Address underlying issues like obesity and inflammation instead of just supplementing cortisol.
- Consider adrenal support containing licorice root if free cortisol is low.
