Weight loss, palpitations, anxiety and restlessness actually sound like signs of over-replacement (too much thyroxin), not under-treatment. Even if
TSH looks normal, free T3 and free T4 might be on the higher side. Need to check all three values together â TSH, Free T3 and Free T4.
Next Steps
Get
TSH + Free T3 + Free T4 tested together and show to her doctor. Also get CBC and blood
sugar done to rule out other causes of weakness. Don't adjust the dose on your own. Consult me on Practo with the reports for proper guidance.
