What causes bilateral kidney stones?

Many friends will find that they have bilateral kidney stones when they go to the hospital for a physical examination. Don't be nervous at first. The treatment technology for kidney stones is now very mature. Unclean diet and a diet low in water can make kidney stones more common. Many people want to know what causes kidney stones. Next, let us learn together what are the causes of kidney stones? After learning, you can better prevent it in your daily life.

1. Excessive protein

Chemical analysis of the composition of kidney stones revealed that calcium oxalate accounted for 87.5% of the stones. The reason why calcium oxalate has such a large specific gravity is that in addition to containing the raw materials of oxalic acid - glycine and hydroxyproline, protein can also promote the absorption of calcium by the intestinal function.

If you often consume excessive amounts of high-protein foods, the calcium, oxalic acid, and uric acid content in your kidneys and urine will generally increase. If excess protein cannot be excreted from the body through the kidneys in time, it will provide conditions for the formation of kidney stones.

2. Excessive accumulation of oxalic acid

The large accumulation of oxalic acid in the body is one of the factors that lead to kidney stones. Foods that people generally like to eat, such as spinach, beans, grapes, cocoa, tea, potatoes, plums, oranges, tomatoes, bamboo shoots, etc., are foods with high oxalic acid content.

3. Excessive intake of fat

Meat from various animals, especially fatty pork, are foods high in fat.

Eating too much will inevitably increase body fat. Fat will reduce the amount of calcium that can be bound in the intestines, thereby increasing the absorption of oxalate. Once the excretion function fails, such as sweating a lot, drinking less water, and less urine output, kidney stones are likely to form under such circumstances.

4. Increased sugar intake

Sugar is an important nutrient for the human body and should be supplemented in appropriate amounts regularly, but adding too much at once will have a counterproductive effect, especially lactose, which can better promote the absorption of calcium and is more likely to cause the accumulation of calcium oxalate in the body, creating conditions for the formation of stones.

5. Reduced inhibitors of crystal formation in urine

Normal urine contains certain substances that can inhibit the formation and growth of crystals. For example, pyrophosphate inhibits the formation of calcium phosphate crystals, while mucin and citric acid inhibit the formation of calcium oxalate crystals. When these substances in the urine decrease, stones will form.

6. Formation of supersaturation

It is seen in the case of too little urine volume and excessive absolute excretion of certain substances in the urine, such as calcium, oxalic acid, uric acid, cystine and phosphate.

7. Abnormal purine metabolism

Animal offal, seafood, peanuts, beans, spinach, etc. all contain more purine. After purine enters the body, it undergoes metabolism, and the final product of its metabolism is uric acid. Uric acid can promote the precipitation of oxalate in urine and form urinary stones.

8. Unhealthy lifestyle

In daily life, too little exercise and activity can easily lead to urinary stones.

9. Regional climate impact

In hot areas, people sweat a lot and their urine tends to become concentrated, forming urinary stones.

10. Poor drinking water quality

The drinking water in some areas is hard water, which contains high levels of crystals and calcium. This increases the level of calcium in people's urine and makes it easier to form stones.

11. Bad eating habits

Drinking too little water will cause your urine to become concentrated, which can easily lead to stones. Eat foods high in oxalic acid and calcium, such as animal offal, spinach, tofu and other soy products, strong tea, wine, coffee, etc. Also, eating too refined food, too much meat, and too little vegetables and other fiber-containing foods can easily cause stones.

12. Nucleation

Homogeneous nucleation refers to the crystallization formation of one type of crystal. Taking calcium oxalate as an example, when a supersaturated state occurs, these two ions form crystals. The higher the ion concentration, the more and larger the crystals.

13. Special Circumstances

The body has a disease that causes hypercalcemia or hypercalciuria. Diseases such as hyperparathyroidism, gout, fractures, paralysis, and hemolytic bone tumors can increase urinary calcium and easily form kidney stones. Urinary tract obstruction due to various reasons causes urine stagnation, and urinary tract infection can also easily lead to the formation of stones.
