A Romanian-language educational video by Dr. Mihail Pautov explaining thyroid anatomy and physiology, how thyroid hormones (T4 and active T3) regulate metabolism, the HPT feedback axis, and the clinical spectrum of hypothyroidism (subclinical → clinical). The speaker covers prevalence (noting higher risk in women >60 y with ~20% prevalence in that group), diagnostic approach (TSH primary test; T4 measured; TSH reference ~0.4–4 mIU/L), differences between T3 (active, 5–10× potency; half-life ~1 day) and T4 (storage form, ~90% secreted; half-life ~7 days), causes and risk factors (iodine imbalance, selenium deficiency, autoimmunity/Hashimoto, certain drugs), common symptoms (fatigue, weight gain, cold intolerance, constipation, dry skin, hair loss, bradycardia, etc.), and management (when to test, levothyroxine substitution 0.5–0.8 µg/kg as starting guidance, administration advice). Practical prevention/support measures (iodine ~150 µg/day, selenium ~55 µg/day—Brazil nut as source, avoid excess iodized salt and extreme restrictive diets, ensure sleep, exercise, reduce stress) are emphasized.
