Hi, this is my first post on here, I don’t really know where else to turn.
I was diagnosed with hypothyroidism at the age of 13, I have been on levothyroxine ever since. Recently my dose has been dropped from 200mcg to 175mcg. My most recent bloods showed a low TSH of 0.02 and a high T4 of 17.9. Since my dose has been dropped I’ve been symptomatic again.
I suppose what I want to know is, can a high T4 cause long term problems?
