Kidney stones are caused by abnormal accumulation of some crystalline substances (such as calcium, oxalic acid, uric acid, etc.) in the kidneys, which is a common and frequent disease of the urinary system, with more incidence in males than in females, and occurring more often in young adults, 90% of which contain calcium, of which calcium oxalate stones are the most common. Kidney stones can cause blood in the urine, renal colic, urinary tract infection, and in severe cases, can lead to hydronephrosis, and then renal insufficiency or even uremia. How to prevent kidney stones? Daily attention to their diet is the key. To control the intake of protein The main components of protein are amino acids. After amino acids are metabolized by the human liver, a large amount of ammonia can be produced. Excess ammonia into the human blood, can lead to the human body uric acid increase, and even can cause hyperuricemia. And the increase of uric acid is an important factor to cause kidney stones. Therefore, avoid eating a lot of high protein foods, such as soy products, animal offal, meat, seafood and so on. To eat less salt Salt will combine with a large amount of free calcium after entering the body, and salt is excreted through the kidneys. If a person regularly eats a high salt diet, it will lead to an increase in calcium concentration in the kidneys and urine. Therefore, people with kidney stones must keep their daily salt intake to less than 3 grams. To control calcium intake Clinical studies have found that more than 90% of kidney stones are formed by calcium or calcium-containing substances. Healthy people should not blindly take calcium supplements. If you have to take calcium supplements or vitamin D because you suffer from certain diseases, you should use it under the guidance of your doctor. In addition, kidney stone patients should eat less calcium-rich foods such as soy products, milk, seaweed, shrimp and sesame seeds. To eat less oxalate-rich food In kidney stone patients, about 60% of patients’ kidney stones belong to calcium oxalate stones. Kidney stone patients should eat less oxalate-rich foods. They mainly include: nuts, cocoa, chocolate, potatoes spinach, grapes, coffee, tea and so on. To drink more water Drinking more water is good for preventing the production of kidney stones, but also to a certain extent, the effect of stone removal. Stones would have been deposited by minerals, and then drink more mineral water, stones may grow bigger and bigger, more and more; strong tea in the ellagic acid, theobromine and other ingredients will promote the formation of stones, like tea cups used for a long time there will be tea scale, should not be drank; sugar water and beverages in the sugar content is high, can change the consistency of the urine, so that the human body to form stones. Therefore, it is best to drink plain water, drink other “water” may sometimes be counterproductive. Summer is the high incidence of kidney stones, the body sweats a lot, a lot of water evaporates through the skin, urination is greatly reduced; in addition, summer people dress “shallow”, the skin is exposed to sunlight for a long time, objectively contributing to the synthesis of vitamin D and vitamin A in the body, these two vitamins can promote the body’s absorption of calcium, and also make the urine excreted in the body, the body’s absorption of calcium, the body’s absorption of calcium. At the same time also make the amount of calcium discharged in the urine increased, easy to form stones. Therefore, it is important to remind people to drink more water in the summer, to ensure that the urine volume of about 1500 ml, to avoid developing kidney stones.
