Episode notes
T3 Controls Cellular Energy
- T3 is the active thyroid hormone needed by every cell for ATP and metabolism.
- Low T3 forces the body into energy-conservation, causing weight retention and fatigue.
Run A Full Thyroid Panel
- Order a full thyroid panel, not just TSH, when symptoms exist.
- Test beyond TSH because tissue-level T4→T3 conversion can be impaired while TSH looks normal.
Personal Experience With Missed Diagnosis
- Rebecca recalled being dismissed by a doctor despite severe symptoms and restrictive dieting in college.
- That experience motivated her to learn deeper testing beyond basic labs.
