What happens to tsh level when thyroid gland is removed?
3 doctors weighed in across 2 answers
It goes up: When the thyroid is removed, there is little or no thyroid hormone and the pituitary will increase TSH production until thyroid hormone replacement is taken.

Goes up: Tsh (thyroid stimulating hormone) works by feedback mechanism with thyroid hormone (t4 and t3). Once the thyroid is removed, the source of thyroid hormone is removed. Without T4 and T3 (liothyronine) to suppress tsh, the TSH level will go up. Replacing thyroid hormone with levothyroxine will keep TSH in the normal range.
