I had to take thyroid medicine every morning on empty stomach because my TSH went up to 4. Regular blood checks every month helped my doctor adjust the dose properly. Baby is perfectly fine now!
My TSH was fluctuating like crazy and my brain was too tired to even understand the reports. Trust your doctor blindly on this one, they will give the exact tiny pill needed.
For thyroid, please don't rely on home remedies or diet changes alone. It is a serious thing for baby's growth, so ask your doctor for thyroid tablets immediately if levels are high. Eat healthy but meds are must.
Actually, for pregnancy, TSH should ideally be under 2.5 mIU/L in the first trimester and under 3.0 in later trimesters. My doctor explained that thyroid hormone is crucial for baby's development, so we must take thyroid medicines regularly if prescribed.
Beti, thyroid is very common nowadays, so don't get scared. Take your doctor's medicine on empty stomach daily, and you can also drink warm coriander seed water which is traditionally good, but only alongside proper medical advice.
