Following a complete removal of the thyroid gland about 5 years ago, i was put on 100mcg of Levothyroxine for which my body was content with and regualr checks of my tsh were within the normal range. Last year i started to suffer from hot sweats and palpitations/insomnia and as such concluded that i was being overmedicated which was confirmed with a TSH reading trending towards the low side of the nominal range. My dosage was reduced to 75mcg for a period and i knew i had to keep a regualr check on the results. Throughtout this transition to a new dose level, i continued to suffer fatigue and occasional muscle aches but believed i was moving in the right direction with the revised dose. A few months later my TSH level was again seen as too low and outside the normal range so my dose was reduced to 50mcg.
With a general feeling of being tired and unwell i was a patient patient and looked forward to good results and and better physical wellness in the weeks ahead. My latest TSH is again very low (0.03) which would indicate that i need to continue reducing my Levothyroxine dose. What i cant understand is that i do not have a thyroid that provides T3 and T4 and as such need some intake of Throxine to function ? My GP is a little confuse by it all and even he advised that i stop taking thyroxine altogether !. The latest GP advice is that i remain on 50mcg and make an appointment with an Endo for further advice in a few months time. My own thoughts are that prehaps my Pituitary gland is malfunctioning and the results are presenting false guidance with the TSH readings or that my body is having difficulty converting the T4 into T3 such that i am not receiving the T3 required to function normally and as such am feeling the side effects of that. Any feedback from those who are aware of similar situation or effects, particulalay from those who have had their thyroid removed woud be much appreciated.
