Re: Hashimoto's and Type 1 Diabetes
Patients with any kind of thyroid problem always need free T4 and free T3 monitored to determine the right dosage of thyroid hormone replacement. TSH alone is not enough for that purpose, because it can so often be inaccurately volatile.
If you want to know for sure if you're taking enough hormone to keep your metabolism running optimally, make sure your MD runs the FT tests and understands that these levels must be at least half the lab's range or above to be optimal... not just "adequate".
It doesn't really matter whether the Hashimoto's is gone or not. It doesn't cause symptoms in and of itself; symptoms happen after Hashi's has damaged or destroyed the thyroid gland tissue. In your case, surgery did that. The treatment is the same for Hashi's-caused thyroid damage or a missing gland.
