Weight Loss Surgery

47 female here with stage 4 CKD. Has anyone had weight loss surgery with CKD? I have heavy protein leakage and my eGFR hovers around the low 20s. I see my nephrologist on Wednesday to discuss a possible kidney biopsy to help determine what the cause of my CKD is. Im assuming its because im obese with poorly controlled type 2 diabetes for a lot of my younger years. Of course hindsight is 20/20 but just seeing what I can do now to stop the progression and if anyone has had luck with weight loss surgery and has seen improvement. Thank you for your thoughts
