TSH lowered fast

Sorry I have another question.

I was diagnosed with hypothyroidism when I had been coughing/flu for 2 months. my tsh was 27. After 1 month on levo 25mcg the tsh was now 3.

I would like to know if the tsh dropped so fast because of the levo or because my flu went away.

When did this actually happen, because your post 8 days ago said you are on 75mcg plus 15mcg T3.

Hey SeasideSusie, this happened january 2022. I am just very interested in how our body works and I want to understand. I read that tsh is often elevated when we are ill.

Just testing TSH tells you very little.

Previous post shows you are on 75mcg levo and 15mcg of T3.

Since adding T3 in mid October

Bloods should be retested 6-8 weeks after being on constant unchanging dose and brand levothyroxine and T3

test early morning and last dose levothyroxine 24 hours before test

Day before test last 5mcg dose T3 approx 8-12 hours before test

Hey SlowDragon, thanks for the information. MD put me on levo based on high tsh in January. He didn't test ft3 or ft4 back then. I asked to test tpo in March and it was very high so I suppose levo was needed.

High thyroid antibodies confirms autoimmune thyroid disease also called Hashimoto’s

Levels can swing wildly up and down early on with Hashimoto’s

Keeping TSH low can help reduce these changes in levels
