Discussions that mention synthroid

Weight Loss board

I was diagnosed with under active thyroid 2 years ago. I was 126-128 pnds then. Now Im 116 pnds without trying to lose weight. Do you think its the medication (synthroid) that is speeding up my metabolism and that is why? Im a little scared as to why I am losing weight.
Another note, I do not eat correctly, sometimes going unit 2:00 without eating a single thing. But I have always done that even when I was 126 pnds.
But then my head starts thinking cancer or something along those lines. Yikes
