As the weather turns warmer, the number of patients visiting hospitals for acute attacks of urinary stones increases significantly, and many patients have to be hospitalized because of severe colic pain that is difficult to relieve, which adds a lot of trouble to their daily lives. So why is summer a high incidence of urinary tract stones? The reason for the frequent acute attacks of urinary stones is mainly related to the weather and personal habits. In summer, the temperature is high, people are particularly prone to sweating, in the case of insufficient water supplementation, it is easy to lead to urine concentration, coupled with many patients excessive greed for cold, excessive consumption of cold food, drinks and other bad habits of life, not only the risk of urinary tract stones increased, but also very easy to trigger an acute attack of stones. In order to prevent stones, the following dietary recommendations are made in the summer: 1, eat less salt because salt and calcium have a synergistic effect in the body, can interfere with the metabolic process of kidney stone drugs, affecting the effectiveness of drug therapy. 2, eat less beef and lamb because beef and lamb contain more purine, which is most easily broken down into uric acid, one of the main components of the formation of uric acid stones. Especially some readers like to eat barbecued meat and drink cold beer in summer, the two mixed together will occur chemical changes in the body, so that the uric acid content in the blood surge, and because of the loss of balance and can not be discharged in time, so the chances of suffering from stones greatly increased. 3, eat less calcium-containing food because calcium is one of the main components of the formation of stones. Therefore, you should avoid consuming foods containing too much calcium such as dried fish, oysters, clams, mussels, snails, seaweed, seaweed, hairy vegetables, dried meat, milk, dates, walnuts, raisins, ribs, bean products, etc. For readers who need calcium supplements, there is a misconception that they should take calcium before bed because they have heard that “calcium is good at night”. It is important to know that part of the calcium in the food at dinner will enter the urinary tract and be excreted from the body, and the peak of calcium excretion is often 4 to 5 hours after the meal. If you eat dinner too late, when the peak of calcium excretion is asleep, so the urine will remain in the urinary tract, the calcium in the urine deposited to form small crystals, over time, will gradually expand the formation of urinary tract stones. Therefore, the best time to take calcium should be 4-5 hours before bedtime. 4, eat less oxalate-rich vegetables because oxalate will combine with the body’s calcium to form calcium oxalate and deposited as stones. Many green vegetables contain more oxalate, especially the highest content in spinach. Therefore, patients with kidney stones should eat less spinach. 5, eat less food rich in vitamin C because vitamin C in the body metabolism process will generate oxalic acid, thus contributing to the formation of oxalic acid stones. Drink more water. Drink more than 3500ml of water every day and keep the daily urine volume at least 2000~2500ml. Because the amount of urine increases, the crystals will not form stones and be deposited. 7. Eat more black fungus because the alkaloids contained in black fungus can promote the secretion of various glands in the digestive and urinary tracts, and help these secreted substances to catalyze the stones and lubricate the pipes so that the stones can be discharged. Black fungus also contains a variety of minerals, which can also produce a strong chemical reaction to various stones, causing them to exfoliate, differentiate and erode, so that small stones continue to debris and shrink, and finally discharged from the body with urine.
