A member asked:
What could cause a tsh to drop from 25 to 3.1 in less than 2 weeks. doctors retested after worsening symptoms. can tsh levels fluctuate that much?
A doctor has provided 1 answer
Yes: Peptide hormones like TSH have short half lives measured in minutes. Adequate treatment with replacement thyroxine would cause TSH to drop rapidly.
