Hello, Preventing calcium oxalate kidney stones involves making certain dietary and lifestyle changes. Here are some remedies that may help reduce the formation of calcium oxalate stones: * Increase water intake: Drinking plenty of water helps to flush out the kidneys and prevent the buildup of minerals that can lead to stone formation. Try and have at least 8-10 glasses of water per day. * Reduce oxalate intake: Calcium oxalate stones are formed when there is an excess of oxalate in the urine. Limit your intake of high-oxalate foods such as spinach, rhubarb, beets, nuts, tea, and chocolate. * Limit sodium intake: High sodium intake can lead to increased calcium excretion in the urine, which can contribute to stone formation. Try to limit your daily sodium intake to less than 2,300 mg. * Get enough magnesium: Magnesium can help prevent the formation of calcium oxalate stones. Good sources of magnesium include leafy greens, nuts, seeds, and whole grains. * Avoid vitamin C supplements: Large doses of vitamin C can increase the excretion of oxalate in the urine, which can contribute to stone formation. Stick to the recommended daily intake of vitamin C from food sources. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. H.
