I recently wrote to my endocrinologist regarding his decision to reduce my levo on the basis of a suppressed TSH. In my email I told him that I had been feeling better on my increased dose of T4 and t3 and that I was disappointed to learn that he had recommended this reduction because my TSH was suppressed even though my T4 and t3 results were well within range. (He recommended the reduction even before my t3 results came back). I also suggested that it was not unusual for TSH to be suppressed whilst on combination treatment and that I understood from research that providing t3 was not over range there was little or no effect on bone mineral density or cardiac disease, which he originally stated were his main concerns. I asked to continue on my current dose and be retested in 6 weeks. I agreed that if my t3 was over range at that time I would be happy to reduce my levo then.
I just received a response. He states that the evidence is well established that TSH suppression, even with normal T4 levels, is linked to reduced bone mineral density and fractures and although the evidence is less well established for those on T4/T3 treatment we still need to be cautious. He has told me I can stay on my current dose but has suggested a DEXA scan to ensure there is no issue with it at present. I don’t know anything about this scan and will have to see what it involves. He asks if this is reasonable? I suppose I will have to accept the DEXA scan but do I just bite my tongue now? After all I’m getting to stay on my current dose. Maybe less said, soonest mended?
