I am Dr. Arun and will be helping you today.

I am sorry that your question was unanswered for long.

Has your thyroid gland enlarged again?

What are your values of T3, T4 and TSH?

Customer: replied 2 years ago.
I don't know if my thyroid gland is swollen. I had bouts of swelling years ago, but it has stopped. My TSH and T3 and T4 is normal.
Customer: replied 2 years ago.
My TSH changes from time to time and my doctors adds more synthroid from time to time. It has been stable for 2 years now.
Expert:  Dr. Arun Phophalia replied 2 years ago.


Once the thyroid gland was burned by the radioactive iodine therapy; TSH estimation is done every 6-12 months to determine the dose of thyroid replacement / Synthroid. This is a routine follow up. The dose of Synthroid may increase due to following reasons;

1) Aging.

2) Thyroid is a labile hormone so dosing need regular adjustment.

3) Secondary hypthyroidsim may ensue later in the life after radioactive thyroid treatment. This may need increasing the thyroid replacement time to time.

There is nothing worrying here if the dose of Synthroid is increased and in the absence of thyroid gland enlargement; you would not need any surgery.
