Study Summary

This trial will study how obesity affects the amount of oxalate in urine, which contributes to calcium oxalate kidney stones.

Who is the study for?

This trial is for adults with a BMI under 30 who have had kidney stones made mostly of calcium oxalate, and those with Type 2 Diabetes showing specific blood sugar levels. It's not for pregnant individuals, people with abnormal urine or blood tests that could affect the study results, anyone with poor kidney function (GFR < 60), or a BMI over 32.Check my eligibility

What is being tested?

The study aims to understand how obesity affects urinary oxalate levels and the formation of calcium oxalate kidney stones. It will explore this link in different groups: non-obese individuals, obese stone formers, and diabetics.See study design

What are the potential side effects?

Since this trial seems observational rather than interventional—meaning it observes participants without administering treatments—there are no direct side effects from medications or procedures listed.
