For a
TSH of 6.4 mIU/L, confirm the diagnosis with additional tests (free T4, anti-TPO antibodies,
lipid profile) and reassess TSH in 6â8 weeks. Treatment depends on symptoms and risk factors. If symptomatic or high-risk (pregnancy, elevated antibodies, heart disease), treatment is more likely needed. Otherwise, monitor TSH and symptoms periodically. Focus on lifestyle modifications: a balanced diet with adequate iodine and selenium, avoiding excess soy and raw goitrogens, regular exercise, and stress management. Recheck TSH every 6â12 months during monitoring. Address any associated conditions like high cholesterol and seek medical advice for persistent symptoms or significant changes.
