Calcium supplements for enteric hyperoxaluria
What is the evidence that calcium supplementation lowers urinary oxalate in patients with post-resection enteric hyperoxaluria
Out of scope for this tool. The focus of this literature tool is the surgical management of IBD. For medical management and drug dosing, please see ChatIBD.com.
calcium supplementation lowers urinary oxalate in post-resection enteric hyperoxaluria in a dose-dependent fashion across the small studies that exist, so the direction of effect is consistent, but the data are short-term, small, and complicated by a concurrent rise in urinary calcium that partly offsets the drop in calcium-oxalate supersaturation 1,2. it works by binding dietary oxalate in the gut, and is most relevant in these patients because their baseline calcium intake and urinary calcium are typically low 1,2.
