I have a normal functioning Thyroid but have several nodules..I had surgery 40 years ago in my teens to remove the 8 i had..they have grown back and I have had biopsies that were benign.every year I do ultrasounds to watch the growth and every year I usually need a biopsy on yet a different nodule.I have a,2.7 cm on my left lobe near my esophagus.I have the option of taking them all out and have a TT..however I am concerned about taking synthroid because of possible weight gain and feeling lousy until I get the right dosage.I am wondering if it is better to keep my thyroid in as long as possible.
