NCT02406664

Brief Summary

The purpose of this study is to determine the change in kidney function and blood pressure after gastric bypass versus conventional medical therapy in morbid obesity. The study mainly focus on glomerular filtration rate(GFR) with known relation to the renal function and 24 hours ambulatory blood pressure monitoring after intervention of gastric bypass or medical treatment.
