I have discussed this issue with T, pcp, pdoc. My first medication caused me to lose A LOT of weight but I was over weight to begin with. However, I lost too much weight in a very short period of time. I was taken off the medication because of it. I tried a few other medications but they didn't seem to work or I had such bad reactions to them. My doctors knew that I wouldn't go on something that would cause significant weight gain an understood why so they have really worked with me. They know how sensitive I am about my weight. I have put some of the weight back on but it was a good thing as I really had gotten too thin.,,,

Talk them as you can see from my experience they understand will work with you.
