I was diagnosed 9 years ago with Type 1 diabetes. The day I was diagnosed, I was also told I also have Hypothyroidsim (which means my thyroid is underactive). I was placed on Synthroid and to be quite honest, when I would try to lose weight I would be successful. This all stopped about a year ago, it has seemed virtually impossible for me to lose weight. My levels are monitored every three months by my Endocronologyst and I am in control. I am scared to death that I am going to pay all this money to get my band and that I will not lose any weight. I would really appreciate any input from anyone out there with an underactive thyroid and what you've gone through and how you're doing on the band. I don't care if the weight takes a little longer to come off, what I'm scared to death about is that I won't lose anything.
