And your question?: It's not clear what your question is but your weight gain could be related to your lower dose of synthroid. Ultimately the best dose is determined by your symptoms and relying on TSH is unreliable. Most people benefit by adding T3 (liothyronine). Ask your Dr. to check Free T3; if not above 3.0 advise adding T3. See https://tinyurl.com/ybf4svoz and https://tinyurl.com/ybnwpcft
