Having had a total thyroidectomy 6 years ago (multiple benign goitres), I have been trying to find the best Levo dose to minimise the effects of permanent hypothyroidism. The hospital discharge daily dose was 150 judged by my weight at that time. However, the side effects after the first few weeks were overwhelming so the dose was lowered to 75 which seemed to be ok for a couple of years. The hypo symptoms became worse again so the dosage was increased in increments to 150. After 6 months the symptoms became intolerable because of the extreme hyper side effects. So the dosage has been reducing gradually since last autumn in increments down to 100 at the moment, with another dose reduction expected to 75 after the blood test.
My previous 3 routine tests results have shown similar pattern ranges. T4 free – high: T3free – low: T3 reverse- high. My new GP is convinced that I am still hyper based on blood tests only.
The last test result taken in March -
T4 free 18.3pg/mL (9.3-17.0)
T3free 2.7ng/L (2.0-4.4).
T3 reverse 0.34 μg/L (0.09-0.35)
I am feeling really unstable. The symptoms seem to be rotating every 2 or 3 days with a cluster of typical symptoms that change from hyper and then to hypo symptoms and then visa versa. Sometimes it appears gradually and sometimes within ½ an hour. How is this possible? Is this still a transition period?
Also, whilst on the 150 dose my weight was constant at 63 kg but since the start of the decreased dose at the end of last year I am gaining weight again - I am now 70 kg and my clothes are getting tighter. Also, although I had a mild form of Hirsutism since I was in my late 20s - following the recent decrease in levo the problem is becoming unacceptable. And over the last couple of days, gritty eyes have been a constant problem.
If anyone can shed a light on what might be going on? I would appreciate your thoughts and perhaps recommend a way forward to discuss with my GP.
Many thanks
