Hello, doctor i am 26 years (F) from India and I have been taking thyroid medication from the past 9 years and I am taking only one medicine everyday in morning i.e thyronorm-100mg. Doctors over here say that thyroid medicines go on for life time, is it so? Recently 3-4 months back i have been taking homeopathy treatment also as i was not satisfied with the allopathic medicinal treatment. Now, my worry is that yesterday only I have done my t3, t4, tsh test and the results are like this : T3- 20.97 (low) , T4-1.00(low), TSH - 150.00 (high).
