Kidney stones are the first common disease in urology, occurring between 20 and 50 years old, mostly in adult males, directly affecting kidney function and causing great harm. In the urology department, kidney stones are the most common disease. 1, drink more water Water can dilute urine and prevent high concentrations of salts and minerals from accumulating into stones. The appropriate amount of water to drink is 2 L of urine a day. Drink water 5 times a day, especially in the morning, before going to bed at night, 1 h after breakfast and 1 h after dinner, drink water at even intervals, it is best to develop the habit of drinking water regularly, do not wait until you feel thirsty to drink, drink water mainly plain water. 2.Supplementation of fiber Add rice sugar bran, can prevent the occurrence of stones. 3.More activity. People who do not like to move easily make calcium accumulation in the blood. For students who sit in classrooms and computers for a long time, it is recommended that they should take part in more physical exercise, such as playing ball and running, after their busy studies to reduce the occurrence of stones or to promote the discharge of kidney stones. 4. Eat less salt If you have stones, you should reduce the intake of salt. The daily salt intake should be reduced to 2~3 g. 5. Do not eat food with too much protein. Laboratory analysis of kidney stones revealed that 87.5% of calcium oxalate was found in the stones. The source of such a large proportion of calcium oxalate is because protein contains oxalic acid as a raw material, but also promotes the absorption of calcium in the intestine. If you often consume high protein foods in excess, it will cause a general increase in calcium, oxalic acid and uric acid in the kidneys and urine, and if you cannot excrete the excess calcium, oxalic acid and uric acid from the body in time, it will form the conditions for the production of kidney stones and ureteral stones. The main reason for the increased incidence of kidney stones in economically developed countries in the world today is this. 6, should not eat food containing high oxalic acid The large accumulation of oxalic acid in the body, is one of the factors leading to kidney stones, urinary stones. Spinach, beans, grapes, cocoa, tea, oranges, tomatoes, potatoes, plums, bamboo shoots, etc. are foods high in oxalic acid. Research found that 200g of spinach, containing 725 mg of oxalic acid, if a person ate all 200g of spinach, 8 h after eating, check the urinary excretion of oxalic acid 20 ~ 25 mg, equivalent to the average total amount of oxalic acid excreted by normal people 24 h. 7, should not eat purine-rich food animal offal, seafood, peanuts, beans, spinach, etc., all contain more purine components. Purine into the body, the end product of metabolism is uric acid, uric acid can contribute to the precipitation of oxalate in the urine. 8, should not eat food containing too much fat eat fatty pork and other fatty foods will reduce the intestinal tract can be combined with calcium, thus causing an increase in the absorption of oxalate, if once the excretory dysfunction, such as sweating, drinking less water, less urine, kidney stones are easy to form.
