Ways to prevent kidney stones

Kidney stones are of different sizes, which have different treatment methods according to their size. If the stone is not too big, it will be removed, otherwise it must be removed by surgery. One of the symptoms that can be The cause of urinary stones is a low volume of urine. In this article, we intend to introduce you to other causes of this issue.

Kidney stones and how they form

You probably know that the thickening of urine causes the sedimentation of the compounds in it and as a result the formation of kidney stones.. The stones formed in the kidney are composed of organic materials and sometimes they are found in different sizes as small or large as a pebble.

Calcium stones are the most common type of kidney stones. Excretion of calcium from the body and as a result the formation of calcium kidney stones increases in these cases:


After consuming large amounts of vitamin D

During prolonged immobility


and after consuming a large amount of calcium.

On the other hand, the reduction of water absorption by the intestine due to diarrhea or water loss in the form of sweating in tropical areas are also known to be effective in creating this type of kidney stones. But its complication is the severe pain caused by the displacement of the stone.

The nutritional advice that kidney stone sufferers should pay attention to is to drink a lot of fluids, which will dilute the urine, and in some cases, by changing the acidity of the urine, stone deposition can be prevented..

14 recommendations to prevent kidney stones:

1- Diabetics should increase fluid intake to more than 3 to 4 liters per day. This work increases the volume of urine and decreases the concentration of stone constituents. People who have kidney stones should consume at least 2 liters of fluids during the day.

2- Never make yourself feel thirsty Because the occurrence of this feeling is a sign of at least 2% reduction in body water.

3- In the case of calcium stones, avoid foods rich in calcium and vitamin D and within the recommended range (2 glasses of milk or yogurt, or 30 grams of cheese).

4- In the case of calcium phosphate stones and ammonium and magnesium phosphate stones, the pH of the urine should be acidified..

5- In the case of calcium oxalate stones, one should avoid consuming foods rich in oxalate (Cherry, plum, raisin, raspberry, rhubarb, wheat germ, tomato, beet, celery, eggplant, leek, parsley, spinach, chocolate, peanut, green pepper, carrot, instant coffee and tea).

6- In the case of cystine stones, the pH of urine should be alkaline.

7- In the case of uric acid stones, the dietary purine should be reduced and the pH of the urine should be alkaline.

8- Reducing consumption of animal protein is also necessary. These proteins increase the amount of calcium, oxalate and uric acid.

9- In people who are prone to stone formation, urinary excretion of calcium decreases. A diet high in fat and salt and low in fiber increases the risk of kidney stones. So these people should increase their dietary fiber.

10- Reducing caffeine intake is another recommendation for these patients. High intake of caffeinated foods increases urinary excretion of calcium and increases the chance of stone formation. The possibility of stone formation in people who consume alcohol is also high.

11- Since vitamin C can also be converted to oxalate, it seems that high intake of vitamin C increases the possibility of kidney stone formation.. However, urinary oxalate levels do not usually increase unless vitamin C intake exceeds 6 grams per day, which has been seen in a few people.

In people prone to stone formation who receive high amounts of vitamin C, supplements with vitamin B6 and magnesium can reduce the risk of increased oxalate in the urine.

12- It is interesting to know that vitamin B6 is needed to break down oxalate and in people whose urine oxalate levels are high, it reduces the possibility of stone formation.. Food sources of this nutrient include bananas, potatoes, lentils and spinach.

13- Foods that acidify urine pH include red and white meat, cheese, eggs, bread and cereals, corn and lentils, plums, tomatoes, plum juice and tomatoes. But the foods that alkalize the pH of urine include milk and its products except cheese, all vegetables except corn and lentils, and all fruits except plums and green tomatoes..

Butter, honey, oil, sugar, tea, coffee and cream are considered neutral foods.

14- Beer can also be useful for those who have calcium oxalate stones.. Of course, it should be consumed several days in a row. If it doesn’t work, there is no point in continuing to use it because the effect of beer is short-term.
