The incidence of kidney stones can be reduced by 86% by increasing the volume of urine by 50%. 2, reasonable calcium supplementation: especially dietary calcium supplementation, kidney stone patients often “talk about calcium”, the wrong belief that the culprit of kidney stones is calcium, in fact, kidney stone patients also need to supplement calcium. The blood is acidic when there is a calcium deficiency, but with reasonable calcium supplementation, the blood is alkaline, which is beneficial to inhibit stone formation. 3, limited intake of sugar: high sugar intake of food can increase the chance of kidney stones, so pay attention to eating less sweets. 4, eat less food with high oxalate content: foods with high oxalate content are tomatoes, spinach, strawberries, beets, chocolate, etc. Excessive oxalate intake is also one of the main causes of kidney stones. 5, be careful to drink milk before going to bed: people who do not sleep well, drink milk before going to bed to help sleep. But after sleep, urine volume is reduced, concentrated, and various tangible substances in the urine increased. And 2-3 hours after drinking milk, it is the peak of calcium excretion through the kidneys. The sudden increase of calcium through the kidneys in a short period of time makes it easy to form stones. Therefore, patients with kidney stones should not drink milk with high calcium content before going to bed. Follow Xuanwu Hospital Urology Department scan the QR code above
