When kidney stones and bladder stones occur, patients often ask their doctors in severe pain: Where did the stone come from in the kidney or urethra? What can I do after surgery to prevent its recurrence? The main reason for the formation of kidney stones is diet. It is caused by excessive intake of the relevant components of the diet that can form stones. Excessive accumulation of oxalic acid. The large accumulation of oxalic acid in the body is one of the factors that lead to kidney and urine stones. For example, spinach, beans, grapes, cocoa, tea, oranges, tomatoes, potatoes, plums, bamboo shoots and other things that people commonly love to eat are the very foods that contain high oxalic acid. Doctors found through research: 200 grams of spinach, containing 725.6 mg of oxalic acid, if a person will eat all 200 grams of spinach at once, 8 hours after eating, check the urinary excretion of oxalic acid for 20-25 mg, equivalent to the average total amount of oxalic acid excreted by normal people in 24 hours. Purine metabolism malfunction. Animal offal, seafood, peanuts, beans, spinach, etc., all contain more purine components. When purine enters the body, it is metabolized, and the end product of its metabolism is uric acid. Uric acid can contribute to the precipitation of oxalate in the urine. If too much purine-rich food is consumed at one time, and the metabolism of purine is out of order, oxalate will be deposited in the urine to form urinary stones. Too much fat intake. All kinds of animal meat, especially fatty pork, are fatty foods. Eat more fat in the body is bound to increase, fat will reduce the intestinal can be combined with calcium, thus causing an increase in the absorption of oxalate, if once the excretory function failure, such as sweating more, drink less water, less urine, kidney stones are likely to form in this case. Therefore, doctors often say that in order to prevent getting stone disease, drink more water on hot days, and drink more water when you eat food with a lot of oil and water, in order to promote smooth urination and dilute the composition of urine, it reduces the risk of getting stones. Sugar increase. Sugar is an important nutrient for the body and should be added in moderation often, but too much at once, especially lactose, will also create the conditions for stone formation. Experts have found that: whether normal people or stone patients, after consuming 100 grams of sucrose, after 2 hours to check their urine, found that the concentration of calcium and oxalic acid in the urine are increased, if lactose is taken, it can promote the absorption of calcium, more likely to lead to the accumulation of calcium oxalate in the body and the formation of urinary stones. Excess protein. Laboratory analysis of the composition of kidney stones revealed that calcium oxalate accounted for 87.5% of the stones. The source of such a large proportion of calcium oxalate is because protein contains glycine and hydroxyproline, the raw materials of oxalic acid, and protein also promotes the absorption of calcium by intestinal functions. If high protein foods are often consumed in excess, there is a general increase in calcium, oxalic acid and uric acid in the kidneys and urine. If the excess calcium, oxalic acid and uric acid are not discharged from the body through the kidney function in a timely and effective manner, the conditions for kidney stones and ureteral calculi will be formed. This is the main reason for the increased incidence of kidney stones in economically developed countries in the world today. From the above factors, to prevent the occurrence of kidney stone disease, it is necessary to change the concept of seeking only one kind of nutrition and pursuing too much nutrition. That is to say, in the daily diet of human beings, not because a certain food is delicious and high nutritional value, it is only to eat this food. We must pay attention to the combination of food, all kinds of food in moderation, even if the body is found to lack a certain nutrient needs a certain food to supplement, should not be a large number of food, because the human body’s digestion, absorption function is limited. The nutrients that cannot be digested and absorbed must be excreted through the excretory organs, which will also increase the burden on the urinary system, even if you do not suffer from kidney stone disease, it is not good for your health. Especially when kidney stones are detected, it is important to restrict the patient from eating foods that tend to promote stone formation during the illness. Kidney stones are a kind of urolithiasis, mostly formed in the hot summer because of the large amount of sweating in summer, and even dehydration in the body, so that urination is reduced, coupled with the long exposure to the sun in summer, ultraviolet radiation on the skin helps the body to increase the synthesis of vitamin D and vitamin A. Vitamin D and vitamin A can promote the absorption of calcium ions in the small intestine, the excretion of calcium in the urine increases, and the stone material in the urine is easy to produce crystalline nuclei, thus forming Stones. The cold weather in winter increases the amount of urine, and the small stones formed are flushed by urine and move downward, causing kidney colic. Therefore, kidney stones are often “formed in summer and developed in winter”. People’s diet is diverse, human metabolism is complex, so the composition of kidney stones is also diverse. Common stones can be divided into five types according to their composition: a calcium oxalate stones: the most common, accounting for more than 80% of kidney stones, formed in acidic or neutral urine, the onset of most young adults, more common in men. Calcium phosphate stones: account for 6-9% of stones, formed in alkaline urine, also more common in male young adults. Three uric acid stones: accounting for 6% of stones, formed in acidic urine, when the urinary pH value is greater than 6.7 stones dissolve, more common in men. Four magnesium phosphate stones: 10% of stones, formed in alkaline urine, dissolve when the urine pH is less than 7.2, more common in females. V cystine stones: rare, accounting for 1-2% of stones, formed in acidic urine, stones dissolve when the urinary pH is greater than 7.0. Drinking plenty of water has a preventive effect on all components of urinary stones. In the hot summer, the risk of urinary stone growth increases significantly when the daily urine volume is less than 1200 ml. If you can make the daily water consumption at 2000-4000 ml, this can maintain the daily urine volume at 2000 ml or more. Magnetized water is more effective in the prevention and control of calcium oxalate stones, which can be given in the morning, between meals and before bedtime. The amount of water drunk in the early morning can be 500-1000 ml. In order to maintain the amount of urine at night, drink 500 ml of water before going to bed, and then drink 300-500 ml of water after getting up to urinate during sleep, and the rest of the water is taken between meals respectively. Drinking large amounts of water can promote the discharge of small stones, dilute the urine to prevent the formation of urinary stone crystals, and slow down the growth of stones.
