Condition: Hyperthyroidism My mother is 65 years old and has been suffering from hyperthyroidism since 2020. She has been taking prescribed medicines regularly, but her condition has not improved significantly. Her TSH levels are consistently very low, and even during medication the thyroid test results keep fluctuating. I have the latest thyroid reports available and can share them for review. Recently, we have noticed several concerning symptoms: Loss of appetite Extreme sensitivity to smells (she cannot tolerate strong smells) Gradual muscle weakness and muscle loss Irregular and fast heartbeat, sometimes her pulse reaches around 140 General weakness and discomfort We would like guidance on why the thyroid levels are not stabilizing despite medication and what further treatment or tests might be required.
