I am hoping someone can shed some light or help me as I am getting quite desperate with this issue. Here we go:
I was diagnosed with autoimmune hypothyroidism just over 20 years ago. I was placed on Levothroxine 150micrograms/day and was fine for ten years. However, about ten years ago something happened (we dont know what still) and my dose had to be increased to 225 micrograms/day. Again I was fine for ten years.
Back in late 2014 my annual thyroid monitoring test showed elevated T4 and suppressed TSH (both out of range), so doctor reduced levothroxine dose to 175 micrograms/day to compensate. I became very hypothyroid within a few weeks, and started to develop hypothermia! At this point doctor increased dose back up to 200, but stated it was a little too high a dose for my borderline blood tests.
I never felt great since that point, but over last 9 months I have got gradually worse hypothyroid symptoms (I can tick them all off the classic symptoms list) and even have developed myxoedema which has become quite debilitating. My blood tests still show that i am borderline over-medicated (and rising) but the symptoms point to hypothyroid and are getting worse by the week.
Both myself and doc are at a loss, and I am awaiting a consultation with endocrinologist when ever that may be. Doctor has ruled out all he can by various blood tests: liver, kidneys, cortisol, Vit B12 active, calcium, iron, and full blood counts.
My latest thyroid test (including Rt3) are below, has anyone anywhere had similar experiences? Last test was May 16 this year and below:
￼TSH: 0.046 mIU/L - Range (0.270 - 4.20)
Free Thyroxine: 22.46 pmol/L - Range (12.000 - 22.000)
Free T3: 5.28 pmol/L - Range (3.100 - 6.800)
Reverse T3: 26 - Range (10.0 - 24.0)
