I've got recent posts on here so won't bore you with too much detail. Currrently trialling T3 only after taking this successfully post TT for 12 months. After 4 years of hell on Levo and Levo / T3 combi I have felt very ill. Last dose 15 T3 with 100 Levo. Stopped Levo 9 days ago and increased the 15 T3 to 30, then 40, then 50. (in divided doses). Feel so much better. Heart rate and BP remain the same - BP 111/70 and HR 70. BUT I take 80 mcg sustained release Propranalol to prevent migraines. (Been on it for 6 weeks) Decided to stop Propranalol two days ago as I thought it may affect Thyroid function / drugs. Heart nearly jumped out of my chest and felt awful. Now back on it and ok.
Thyroid specialist nurse explained that T3 limits effect of Propranalol but Propranalol doesn't affect T3 absorption. She further explained that there was a problem with Propranalol affecting conversion of T4 to T3 but that wouldn't be an issue if on T3 only. So far so good. Understand all that. Just confused that it's said that Propranalol affects Thyroid blood results. If it does show increased TSH etc doesn't that mean that it's effectiveness is being impaired? Can't quite get my head round this.
Also a question about D102 gene. Understand that faulty gene can cause intolerance of Levo. I'm certainly intolerant but TSH is consistently 0.02 on combi dose described above. Would a TSH like that contraindicate faulty gene?
Many thanks for reading this everyone x
