Lap-Band is the only wise choice in your situation, as it is the only adjustable weight loss procedure available today, so not only you will lose the weight prior to your pregnancy, but also you will have control over your weight loss. If during the pregnancy, you need additional nutrition, or if you suffer from severe morning sickness, and if you want to reverse your restriction, Lap-Band is the only modality that will allow you to do so.
Best of luck!
