Weight loss surgery is the most effective weight loss treatment available, but the direct effect on chronic kidney disease is less widely understood. Early research shows some improvement in kidney function may occur and candidacy for kidney transplantation can be improved with weight loss following surgery. To date, no randomised controlled trial has been performed to examine the effect of weight loss surgery on the progression of chronic kidney disease. This randomised trial will allocate patients to either lifestyle modification with diet, exercise and pharmacotherapy, or weight loss surgery to remove two thirds of the stomach using the laparoscopic sleeve gastrectomy procedure. This study aims to evaluate weight loss surgery vs lifestyle modification in patients with chronic kidney disease with estimated kidney function of 20-60% and morbid obesity (BMI 35-45) in terms of kidney function, cardiovascular disease risk factors and all-cause mortality.
