Summary

This study looks at whether gastric bypass surgery can protect the kidneys of people who are severely obese and have chronic kidney disease. Researchers measured kidney function before and one year after surgery in 14 patients. The goal is to see if the surgery improves the balance between kidney filtration and body fluid volume.

What this could lead to
