In brief: It Goes Up

Those who have thyroidectomies need to take thyroid hormone replacement, levothyroxine.
Thyroid stimulating hormone (TSH) comes from the pituitary and increases when thyroid hormones are below normal. Elevation in TSH often indicates hypothyroidism. Adequate levothyroxine replacement keeps the TSH level normal.
