Hi Maria,
My name is Tina and I am a RN I specialize in Nephrology and my patients are on dialysis. I live in the US 25 miles outside of NYC.
I actually have a patient that is on dialysis get the lap band 2 weeks ago. She is doing fine. If your condition is stable there is no reason that you can not be banded ( I do not know the rest of your medical history however). I was banded on 4-16-08 and have lost 20lbs. It is not so easy , but , it is worth it. I had pain for about 3-4 days, and some days I am nausiated. I feel so far that the band is going to affect everyone differently as I compare myself to others comments on this site. Ask your doctor questions and I hope you have a nephrologist (DR. specializing in the kidneys) I am sure you will need medical clearance from him/her.
Good luck!
