Thoughts about Lap Band surgery?

I’m a 27 year old female, overweight my entire life. My family on both sides is prone to being overweight/poor metabolism. My family on my dad’s side is extremely prone to diabetes, and I have already tested hypoglycemic on my last round of bloodwork in April of this year. Also, I’ve struggled with sciatica and two herniated discs for 12 years.

It was suggested to me that because I am sufficiently overweight, pre-diabetic, and suffering back problems, and because I’ve tried multiple diets and never succeeded, that I would be a good candidate for Lap Band surgery.

Have you known anybody who’s had the surgery? What does it entail? What risks am I looking at, realistically?
