i had a total thyroidectomy a year ago . Weight gained during RAI then with medication it stabilized after a year of regulation
With a normal thyroid lab, unlikely the thyroid is contributing to weight at this point. After surgery, medications will keep thyroid regulated and should not significantly effect weight. Most weight gain is a simple issue of taking in more calories than we burn off.
I'm experiencing the same symptoms as you. My blood work is normal but I have alot of the signs of Hypothyroidism. I'm scheduled for a thyroidectomy on Nov 8th. I hope and pray that this will help my current situation. I pray all goes well with your surgery and you also find relief afterwards.
