Urolithiasis stones are stones from the urinary tract, mainly including stones from the kidney, ureter, bladder, and urethra. It is a common and frequent disease in the south. Most of the urinary stones originate from the kidney, and most of them are mixed stones, mainly divided into uric acid stones, phosphate stones and calcium oxalate stones according to their composition. The dietary considerations for patients with urolithiasis are common and different. Common: 1, drink more water, we measure how much water each person drinks a day, to the amount of urine a day as the standard. Chronic dehydration or insufficient water intake is closely related to the formation of urinary stones. Drinking more water can reduce the incidence of urinary stones. Drinking 2500ml of fluid per day can stop the occurrence of neoplastic stones in people with high urinary calcium. 2. Eat more vegetables and fruits to supplement vitamins. Diet should be diversified and rich in nutrients and vitamins, such as fresh vegetables, cucumber, bean sprouts, mung bean sprouts, fresh fruits, such as apples, sorbets, watermelon, oranges, etc. 3, eat more low-sugar, low-fat, low-sodium diet. Urological stones diet should be light, low protein, low fat. 4, avoid “thick” food sodium: high sodium diet can increase the tendency of urinary calcium salt stones, the amount of salt in the food to <10g/day is appropriate. 5, avoid eating food containing calcium oxalate. 6, avoid drinking milk before bedtime. Differences: 1, uric acid stones: avoid raging wine, old fire soup, high protein food and animal offal (for example: animal liver, kidney, brain, heart, intestines, etc.). Avoid high sugar, and high fat diet, the above will increase the risk of stone formation. Easy to eat more alkaline food (food containing more minerals such as potassium, sodium, calcium, magnesium, the final metabolites in the body are often alkaline, such as, vegetables, fruits, dairy, soy and mushroom food, etc.), usually should eat more coarse grains and vegetarian food. 2, oxalate stones: most stones contain oxalate, so reducing urinary oxalate can reduce the occurrence of stone disease. Large doses of vitamin C will increase the level of urinary oxalic acid, and avoid strong tea, do not use large amounts of chocolate, spinach, beets, oranges, rhubarb, nuts, strawberries, wheat bran, mushrooms, potatoes, peppers, chestnuts, coffee, cocoa, persimmons, prunes and other foods that may cause high oxalic acid urine. 3, phosphate stones: for infectious stones, usually avoid triggering urinary tract infection, drink more water. 4.Calcium: Calcium salt is the main component of urinary stones. It is generally believed that an increase in calcium intake increases the risk of stone formation. However, excessive restriction of calcium intake will not reduce but increase the occurrence of stones. It is recommended to maintain a normal calcium intake of 1000mg per day for adults and 1200mg per day for those over 50 years of age. 5. Citrate: Citrate is a natural inhibitor of urinary stone formation, which can reduce the concentration of urinary calcium and the saturation of calcium oxalate and calcium phosphate in urine. Daily supplementation of potassium citrate can significantly increase urinary citrate and urinary PH, reduce the recurrence rate of urinary stones, citrus is more commonly used as an adjunct to the treatment of low-citrate calcium-containing kidney stones. 6, wine: long-term heavy drinkers high urinary calcium and high urinary phosphorus more obvious, easy to form stones. On the contrary, moderate drinking of alcohol-induced diuresis can reduce the concentration of urinary components, reducing the incidence of stones. In short, moderate alcohol consumption does not increase the risk of stone formation. 7, drugs: try not to take or take less drugs related to stones, such as vitamin C, aspirin, sulfonamides. 8, urinary stones diet should be prohibited cholesterol-containing animal liver, kidneys, brain, sea shrimp, clams and crabs. Eat less food containing high oxalic acid and calcium, such as spinach, strawberries, chocolate, carrots, milk replacer, dairy products, beans, egg yolk, sesame paste, pickled scallops, etc. It is best not to drink alcohol, strong tea, strong coffee, cola, black tea.
