Bariatric Surgery Kidney Stones

ClinConnect Summary

This clinical trial is looking into how diet and sex might influence the risk of developing kidney stones in people who are planning to have gastric bypass surgery. The study will involve participants following a specific diet provided by the clinic for six days and attending three visits at the research clinic. The goal is to gather information that could help understand how these factors affect kidney stone formation after surgery.

To participate, individuals must be between the ages of 18 and 75 and should not have a personal or family history of kidney stones. They should also be approved for surgery at the Bariatric Surgery Center at the University of Chicago Medicine. However, those with certain medical conditions, such as kidney disease or vitamin D deficiency, will not be eligible. If you join this study, you will help researchers learn important information that could benefit future patients undergoing bariatric surgery.
