Wow, you are HUGE!!
My Doc will not do the gastric if you are over 400, I was 350 now 176 had my gatro 1 year ago last May.
I have had a few issues but I am getting a little better a day at a time.
I have other issues as I was diabetic for 21 years, and my kidneys are shutting down, have had a few eye surgery's, they will never be the same but i am seeing again!
I wish I had it done before my health got so bad, but the surgery sucked back then. But it has fixed a lot! No more High BP, No more diabetes, no more cholesterol.
Good Luck to ya!
