Micronutrients & recovery
Post-bariatric patients should restrict high-oxalate foods and maintain adequate calcium intake (1200-1500 mg/day) to bind intestinal oxalate and prevent enteric hyperoxaluria.
To prevent kidney stones after bariatric surgery, you must limit high-oxalate foods (like spinach and rhubarb) and ensure you are getting 1200-1500 mg of calcium daily, preferably from supplements like calcium citrate if you have dumping syndrome. This calcium binds oxalate in your gut so it doesn't reach your kidneys.
GoodSupportsHIGH confidence
A diet rich in oxalate and/or poor in calcium decreases the generation of unabsorbable calcium oxalate (CaOx) complexes ultimately leading to a higher amount of free oxalate in the intestinal lumen... the recommended amount of calcium intake after BS should be at least 1200–1500 mg/day, provided by diet or supplements
