Welcome Isobel...you've made a strong decision for yourself, I hope you are already proud of yourself for that.
My primary reason for WLS was definately to increase my longevity. I was classified as morbidly obese and had every precurser to heart disease, stroke or diabetes which runs strong in my family.
Last Fall (2011), I was getting winded just walking from the parking lot where I work to my office building right next door...the writing was clearly on the wall. I simply decided that was it and I prayed for the strength to commit to a healthier life. The next day, by chance I found out Kaiser covered WLS. I always thought only PPO's covered it. I made an appointment with my primary for my annual physical with the intent of asking if I might qualify for WLS. Amazingly, after my appointment, I asked my primary, and she agreed this would be a great option for me, and she referred me that very day to the Options program at Kaiser.
Fast forward....I had surgery 4/6/12 and I have no regrets whatsoever. This has truly been life changing. I saw on your profile your stats, and we are both shorty's and started at a similar weight. You will be amazed at how much better you will feel as you move forward on this journey toward better health. I am down close to 80 pounds since last summer and I feel better than I have in decades!
You are already a beautiful woman....but imagine yourself seeing that beauty peeking out in a size 6 or 8 outfit??
Good Luck on your journey!!!
