Study Summary

This trial will help researchers understand how obesity affects the amount of oxalate excreted in urine, which could lead to new ways to prevent calcium oxalate stones from forming.

What is being tested?
The study is testing the impact of a controlled low oxalate diet on non-obese and obese individuals without kidney stones. The goal is to understand how obesity affects the body's production of oxalate, which could lead to new treatments for preventing kidney stones.See study design
What are the potential side effects?
Since this trial involves dietary changes rather than medication, side effects may include digestive discomfort due to diet adjustment. No significant medical side effects are expected from following a controlled diet.

5Patient Review
Dr. Assimos and his team are outstanding. He removed a kidney stone for me in 2018 and was very patient in answering all my questions. The recent telehealth visits have been great as well — on time and efficient. Nurse Harvey is extremely responsive and helpful. Both Assimos and Harvey gave me their cell numbers for emergencies, which is rare these days. I highly recommend him and his team.
