Kim,
The reasons for considering surgery are become healthier. Avoiding diseases associated with being overweight, diabetes, high blood pressure, heart disease. It's so important to keep the important things always before you. As for me I had surgery 6 weeks ago. And I had the same thoughts but the good out weighs the bad in the long run.
Right before my surgery I was diagnosed with diabetes. Hopefully this will cure it completely that is my prayer.
Quality of life is what is important for me and possibly the same is true for you.
