Experimental: Dietary supplement
Dietary Supplement: Calcium Carbonate
There is a regimen for dietary supplement intake that will be provided to study participants.
Other Name: CaCO3
- Molar ratio of urinary calcium:oxalate in relation to the supersaturation product of calcium oxalate [ Time Frame: 7 days ]
Molar ratio of urinary calcium:oxalate in relation to the supersaturation product of calcium oxalate will be calculated from the 24-hour urine test.
The patient will take dietary calcium for 7 days and then we will evaluate their urine chemistry. Additionally, 24-hour urine collections are considered the standard for urinalysis in comparison to spot urine chemistry. The initial data, prior to calcium supplementation, will serve as the control, providing the patient's baseline risk for kidney stone formation.
- Optimal level of Ca supplementation for prevention of stones in Crohn's patients [ Time Frame: 7 days ]Practical guidelines for physicians managing Crohn's patients will be developed based on the optimal Ca supplement dosages and determine the optimal level of calcium supplementation in each patient, based on urinary parameters from 24-hour urine.
