I may be going against the grain on this one as most of my colleagues in the thread recommend achieving your weight loss goal (losing an additional 30 lbs) prior to considering elective cosmetic surgery. I used to do the same, as this is what we are taught. Historicaly, I saw patients who wanted to lose weight, say 30 lbs, and I told them to excercise, eat well, get a trainer, join a gym and then see me back in 3-6 months. They would do all the above, see me back in the office and say," Well I did it all, lost 15 lbs, then got tired of it, quit and gained 25 back. Now, I weigh more than I did 6 months ago and feel emotionally worse!"
Now, I tell patient to evaluate their current weight loss trends, has it been a continued steady/aggressive loss or a plateau with gradual loss? Surgery during the gradual loss, even if you are not totally at your goal "lowest" weight, can have dramatic effects. Namely, after recovering from surgery you will feel physically, emotionally and spiritually changed. You will want to go to the gym, your clothes (both work out and casual) will fit better and you will typically (I see it all the time) BLOW past your previous weight loss goal of 30 lbs and may lose more and maintain it.
Again, this is not what every plastic surgeon experiences with his/her patients, but I see it all the time in my practice and as such have changed my tune.
Talk with your surgeon and good luck!
