Dietary Treatment of Hyperoxaluria Following Jejunoileal Bypass

Hyperoxaluria is a common consequence of intestinal resection1 and jejunoileal bypass operations2. It may result in renal failure due to oxalosis3. High intestinal absorption of oxalate is thought to be responsible for the hyperoxaluria4,5. Peroral supplementation with calcium reduces the degree of hyperoxaluria under “metabolic ward” conditions6,7. In patients living at home, however, the effect seems to be doubtful8. Diets low in oxalate9 and fat4 likewise decrease oxalate excretion under metabolic ward conditions. Little is known of the effect of such diets under outpatient conditions. The aim of the present investigation was to observe the effect of low-oxalate, low-fat diet on the urinary excretion of oxalate in patients with hyperoxaluria following jejunoileal bypass living at home.
