I had hyper symptoms (sudden anxiety, heart palps, hair
loss, lump in throat, insomnia) but I gained
weight. This started almost immediately after I quit smoking. I took Chantix to quit. Finally got blood work done and in Feb., my TSH was .01. Radioactive iodine uptake and scan confirmed diagnosis of hyperthyroid. Had another test in July and my TSH rose to 4.05. Still no treatment but doc felt sure my thyroid "burned out" and I had become hypothyroid.
