Hello all - I am a 25yr old female. I had a thyroidectomy back in 2000 (they left 3 grams). They were hesitant about doing it b/c I was so young, BUT my thyroid was so diseased that they had no choice. Well...after my surgery I went through the "normal" stuff: weight fluctuation, hair loss, mood swings, etc. It eventually stopped and I lived normally and happily throughout the rest of high school and even college. Now, years later, I am struggling with thyroid problems again. I've undergone more radioactive iodine 3 times in the last 2 months...then I had a biopsy done. Thankfully, it is not cancer. I am grateful for that completely, but still overwhelmed and frustrated because I have no clue as to why I am going through all of this again. There's nothing left to take out of my body, right? So my question is...what could be wrong? what other complications/diseases/illnesses can come YEARS AFTER a thyroidectomy? I hope someone has had this same experience and can shed some light on such a gloomy issue. Any thoughts or comments are more than greatly appreciated. Thank you =)
