1. Urinary stone patients should not eat more sugar

Urinary stone patients eat too much sugar, not only hinder the treatment, but also promote the further formation of urinary stones. It has been proven that the concentration of calcium ions in the urine, oxalic acid and the acidity of the urine will increase after taking sugar. Calcium and oxalic acid can promote the formation of stones, all three at the same time increase more likely to form stones. Because the increased acidity of urine can make calcium urate and calcium oxalate easy to precipitate, prompting the formation of stones.

So, patients with kidney, ureter and bladder stones should not eat more sugar.

2. urinary tract stone patients avoid eating spinach

According to the analysis, urinary tract stones, the most important component of calcium oxalate. China's urinary tract stone patients whose stones are composed of calcium oxalate, accounting for about 87.5%. In normal times, a normal adult, oxalate excreted from the urine for 12 to 40 mg per day.

These oxalate part from the food, if the food in the oxalate intake is too much, the urine calcium oxalate is in supersaturation, excess calcium oxalate crystals may be precipitated from the urine and the formation of stones. In food, the highest oxalate content is spinach, and spinach is one of the vegetables that people often eat. So how does eating spinach change urinary oxalate excretion? Researchers have made a test on 10 healthy people, let them eat blanched and sautéed spinach, and then measure the urine.

The results after eating 200 grams of spinach, urinary oxalic acid excretion increased significantly, especially after eating 2 to 4 hours to reach the peak, 8 hours later is still higher than the level before the test, than those who did not eat spinach increased oxalic acid 20 to 25 mg, close to the average amount of oxalic acid in the general 24-hour urine. The test also found that those who ate sautéed spinach had higher urinary oxalate excretion than those who ate blanched spinach.

See, urinary tract stone patients should not eat spinach, because their urine calcium oxalate itself has been in a state of supersaturation , if the food, it may aggravate the condition.

If the urinary tract stone patients, through surgery has been removed from the stone, avoid eating spinach can prevent recurrence. Healthy people eat spinach, drink more water, can dilute the urine, reduce the concentration of urinary oxalic acid; more hot food method, which is beneficial to the prevention of stone

3. Kidney stone patients should not drink milk before going to bed

In recent years, advocating the evening drink milk a lot of people, the reason is that the milk contains tryptophan, which helps to sleep.

This is undoubtedly appropriate for generally healthy people, but it is different for people with kidney stones or those who have been cured. The reason is: after a person sleeps, the amount of urine decreases, and all kinds of tangible substances in the urine increase, which can make the urine thicker. Since milk contains more calcium, most of the kidney stones contain calcium salts. The most dangerous factor for stone formation is the sudden increase of calcium concentration in the urine for a short period of time. Drinking milk after 2 to 3 hours, it is calcium through the kidneys to eliminate the peak, so then is in a state of sleep, urine concentration, calcium through the kidneys more, so easy to form stones.

Therefore, kidney stone patients should not drink milk before going to bed. In order to avoid this risk, you can drink at night before going to bed 4 hours ago.

4. In recent years, a variety of reports talk about calcium supplementation, calcium intake increases, calcium excretion from the urine increases, and high-calcium urine increases the risk of kidney stones. Oxalic acid and other high intake, easy to combine with calcium to form stones. However, it has also been reported that calcium ingested through the diet can combine with oxalic acid eaten at the same time to form calcium oxalate, which is excreted from the feces, in turn reducing the amount of oxalic acid that may be absorbed, and therefore does not increase the risk of kidney stones.

But calcium supplements taken outside of the diet do not have this effect. Calcium supplements should be taken with particular caution in people with a history of kidney stones.

5. People with urinary stones should be careful to drink plenty of water and exercise. Drinking water and exercising while whacking the urinary tract is good for when the stones are expelled.

What should be noted in the diet of patients with kidney stones

There are many factors that cause kidney stones, such as metabolic disorders, hyperparathyroidism, urinary tract infections, obstruction, or chemical factors, and many other unknown causes.

Stones are divided into oxalate stones, phosphate stones, urate stones, calcium salts, cystine stones and so on, according to the main crystal components contained. According to incomplete statistics, the composition of the stones varies from region to region, generally oxalate and phosphate stones are more. Therefore, the diet should be controlled according to the nature of the stones.

Oxalate stones: most of them are generated from food, and some of them can also be generated by endogenous mechanisms.

The diet should be free of vegetables high in oxalic acid, such as spinach, amaranth, water spinach, green garlic, onions, wild rice, and all kinds of bamboo shoots. Oral folic acid 5 mg, pyridoxine 10 mg can prevent glycine into oxalic acid. Patients suffering from such stones should drink more water.

Phosphate stones: due to the formation of alkaline urine, so we should eat more acidic food, while limiting the high calcium-containing foods. Become acidic foods such as livestock and poultry meat, fish and shrimp, eggs, cereals peanuts and so on.

Urate stones: is caused by hyperuricemia, so it should be prohibited to eat high purine-containing foods, such as animal offal, thick broth, mushrooms, peas, lobster, sardines, anchovies, fish roe and so on. You should eat more vegetables and fruits and drink more water to reduce uric acid concentration.

Calcium salt stones: it is advisable to limit the calcium-containing milk, cheese, shrimp, etc.. You should eat more acid-forming foods, such as meat, poultry and eggs, to make the urine acidic and drink a lot of water.

Cystine stones: it is important to limit methionine and acidic foods (animal foods) and eat more alkaline foods (plant foods) to make the urine alkaline and drink plenty of water. .
