Hello – Having thyroid hormone levels out of balance can certainly impact body temperature. However, as Karen pointed out, other issues like menopause can have an impact as well. Are your levels currently stable? And have you mentioned these symptoms to your doctor? Also, hopefully, he/she is determining your dosing with the Tapazole based on Free T4 and T3, and not just on TSH. TSH can remain suppressed for quite some time in Graves’ patients, and the latest medical guidance notes that this is not a good benchmark for making dosing decisions early in the process.
In terms of the three treatment options, all have risks and benefits. The “Treatment Options” thread in the announcements section of the forum has two nice links that go through the pros and cons of each option.
Hope that you can get some relief soon!
