I read tht TSH rise in pregnancy. I'm hypothyroid n had TSH 4.57 b4 a chemical pregnancy.8 days after 4wk pregnancy miscarriage, its reduced to 0.25. Y?

Lab error. Hi again, I previously tried to answer your question. Now that I can see that it was the TSH reduced to 0.25, I have to suspect lab error. There would be no reason for your TSH to fall that much during this episode. Either it was mismeasured or misreported, and should be 2.5 mIU/L. Test needs repeating. Best wishes! Read more...

Dx hypothyroid in April, been on synthroid (thyroxine) 0.025mg x 3 months, but TSH went higher (~13) w/ normal ft4. Could viorele birth control cause high TSH?

What's the next dose. Don't think so. More likely it is because 0.025mg is the smallest Synthroid (thyroxine) pill. Synthroid (thyroxine) comes in about 12 sizes, from 0.025mg to 0.300mg. If one's doctor started her on 0.025mg and there is no drop in the TSH, one can ask at her follow-up visit (there is always a lot of follow-up until the proper dose is found and the TSH is normal) what the next dose is.
