What causes kidney stones? What causes kidney stones?

Excessive oxalic acid accumulation (25%):

The accumulation of oxalic acid in the body is one of the factors that lead to kidney urinary stones. Such as spinach, beans, grapes, cocoa, tea, oranges, tomatoes, potatoes, plums, bamboo shoots and other things that people generally love to eat, are foods with high oxalic acid. Doctors have found through research:

200 grams of spinach contains milligrams of oxalic acid, if a person eats all 200 grams of spinach at a time. Some foods are easy to cause stones to fall, 8 hours after eating, check the amount of oxalic acid excreted in the urine is 20-25 mg, which is equivalent to the average total amount of oxalic acid excreted by a normal person in 24 hours.

Purine metabolism disorder (20%):

Animal offal, seafood, peanuts, beans, spinach, etc., all contain more purine components. After purines enter the body, they are metabolized, and the final product of its metabolism is uric acid. Uric acid can promote oxalate precipitation in the urine.

If too much purine-rich food is eaten at one time, and the purine metabolism is abnormal, oxalate will be deposited in the urine and urinary stones will be formed.

Too much fat intake (15%):

Meat from various animals, especially fatty pork, is a fatty food. Eating more body fat will inevitably increase, fat will reduce the calcium that can be bound in the intestines, thus causing an increase in the absorption of oxalate, if there is a failure of excretory function, such as sweating more, drinking less water, less urine output, kidney stones are likely to form in this case. Therefore, doctors often say that in order to prevent stone disease, you should drink more water on hot days, and drink more water when you eat oily and watery food, so as to promote smooth urination and dilute the urine composition, which will reduce the risk of getting stones.

Increased sugar content (10%):

Sugar is an important nutrient for the human body, and it should be supplemented frequently and appropriately, but adding too much at once, especially lactose, will also create conditions for the formation of stones. Experts found that both normal people and stone patients, after eating 100 grams of sucrose, after 2 hours to check their urine, found that the concentration of calcium and oxalic acid in the urine increased, if lactose is taken, it can promote the absorption of calcium, and may lead to the accumulation of calcium oxalate in the body and the formation of urinary stones.

Protein overload (10%):

Laboratory analysis of the components of kidney stones revealed that calcium oxalate accounted for in the stones. The reason for such a large proportion of calcium oxalate is that in addition to glycine and hydroxyproline, which contain oxalic acid, protein can also promote the absorption of calcium by intestinal function. If you regularly consume too much high-protein food, the calcium, oxalic acid, and uric acid in the kidneys and urine will generally increase.

If excess calcium, oxalic acid, and uric acid cannot be excreted from the body in a timely and effective manner through kidney function, the conditions for kidney stones and ureteral stones will be formed. This is the main reason for the increase in the incidence of kidney stones in developed countries in the world today.

The main cause of kidney stone formation is diet. It is caused by an excessive intake of stone-forming components in the diet.

Hello, according to your situation, the symptoms of kidney stones are mainly caused by diet, lifestyle habits, etc., and you need to control your diet.

Stones are not very big, and they can be expelled by drinking plenty of water and using some medications such as the stones you said. If the stone enlarges further, and there are obvious symptoms such as low back pain, nausea and vomiting, ultrasound lithotripsy is recommended, which affects kidney function, and surgery is recommended**. Hope it helps.

What are kidney stones? How is it formed?

The irrational diet is mainly caused by the frequent consumption of high-fat, high-protein and other foods by patients with kidney stones. Eat foods high in sugar regularly. These irrational diets will create conditions for the formation of kidney stones.

Drinking too little water, some people do not pay attention to drinking water, or wait until they are thirsty to drink water, at this time the body is already seriously dehydrated, and the kidneys are not flushed. Increase the chance of kidney stone formation. Lifestyle habitsSome people often use drinks instead of drinking water, and regular drinking of beverages, especially beverages such as cola, will increase the concentration of urine, resulting in an increase in the composition of calcium in the urine and increasing the risk of kidney stone formation.

If you have kidney stones, you can drink Defu Yu Shiqi tea to help expel stones. Eat more fungus, do not eat spinach, beans, grapes, cocoa, tea, oranges, tomatoes, potatoes, plums, bamboo shoots because these foods have a high oxalic acid content, animal offal, seafood, peanuts, beans should also be eaten as little as possible, especially fatty pork. Drink more boiled water, the concentration of calcium ions and oxalate will be reduced, and calcium oxalate stones will not be formed.

Studies have shown that increasing urine output by 50% can lead to the onset of kidney stones.

There are many reasons for the formation of kidney stones, in layman's terms, the reason for the formation of kidney stones is because of the formation of conditions that are easy to deposit crystals in the urine at the site where the urine flow rate is slow, while multiple stones are formed because there are multiple deposition centers formed and exist, and the crystals in the urine will continue to precipitate on these centers, and eventually multiple stones are formed. Immediately form stones, you can use Depu Zhai tea to discharge it, whether it will have a lot to do with personal physique, some people are susceptible to stone disease, some people are not susceptible to it, and what food to eat, living habits, living area and other factors are not very related. Kidney stones are common diseases of the urinary system, more common in men, more in women than in women, more in young adults, there is no obvious difference in the incidence of bilateral, there are many factors affecting the formation of stones, age, gender, race, heredity, environmental factors, dietary habits and occupation are related to the formation of stones.

Metabolic abnormalities of the body, obstruction of the urinary tract, infection, foreign bodies, and the use of drugs are common in stone formation**, and the clinical manifestations are soreness and discomfort in the lower back, or dull or dull pain when physical activity increases. Colic pain caused by small stones often occurs suddenly, and the pain in the lower back and abdomen is like a knife, and it is paroxysmal.

1.Changes in urine quality and quantity: too much stone forming substances in the urine, changes in urine pH [urine persistent alkaline predisposition to phosphate stones], urinary tract infections, etc.

2.Local urinary factors: urinary stasis [avian tract malformations and obstruction], urinary tract foreign body.

3.Systemic factors: metabolic changes [gout hyperthyroidism], dietary factors [low intake of animal protein], low water intake.

Dongzhimen Hospital, Beijing University of Chinese Medicine-Department of Urology- Shi Jing-Chief Physician-Those reasons are easy to lead to kidney stones.

Hold your urine and drink too much water that contains minerals. (e.g. mineral water).

There is usually no clear single cause for kidney stones, although a variety of factors may increase the risk.

Kidney stones form when urine contains more crystal-forming substances, such as calcium, oxalic acid, and uric acid, than diluted substances in the urine. At the same time, there may be a lack of substances in your urine that prevent crystals from sticking together, creating an ideal environment for kidney stones to form.

Symptoms of kidney stones begin with pain in or near the back or side. If it is very painful, it may resemble a violent stinging pain. You may not be able to urinate.

Do not urinate for more than 8 hours, otherwise it may become blocked. In some cases, you may vomit and have a fever. These signs can mean kidney stones or an infection known as a UTI.

You may not have pain, but there are traces of blood in your urine. If you think it's kidney stones, see a urologist. They will do a test of your urine and take x-rays to see if you have kidney stones.

Types of kidney stones.

Knowing the types of kidney stones can help determine** and may provide clues about how to reduce your risk of getting more kidney stones. If possible, if you pass a kidney stone, try to save it so that you can take it to your doctor for analysis.

Types of kidney stones include:

Calcium stones. Most kidney stones are calcium stones, usually in the form of calcium oxalate. Oxalate is a naturally occurring substance in food, and the liver also produces oxalate on a daily basis. Some fruits and vegetables, as well as nuts and chocolate, are high in oxalate.

Dietary factors, high doses of vitamin D, intestinal bypass surgery and several metabolic abnormalities can increase the concentration of calcium or oxalic acid in the urine.

Calcium stones may also appear in the form of calcium phosphate. This type of stone is more common in metabolic conditions, such as renal tubular acidosis. It can also be associated with certain migraines or taking certain seizure medications, such as topiramate (topamax).

Struvite. Struvite stones are formed after an infection such as a urinary tract infection. These stones can grow quickly and become very large, sometimes with few or no warnings.

Uric acid stones. Urine stones can form in people who don't drink enough water or lose too much, people who eat a diet high in protein, and people who have gout. Certain genetic factors may also increase your risk of uric acid stones.

Cystine stones. These stones form in people with hereditary disorders that cause the kidneys to excrete too much of certain amino acids (cystinuria).

1.Metabolic abnormalities in the body: Abnormal metabolism in the body, acid-base imbalance, can lead to the occurrence of kidney stones.

2.Drug factors: Long-term use of drugs that can lead to high urine concentration and low solubility is more likely to develop kidney stones.

It is because of irregular life, and people who like to drink strong tea, coffee and drinks with very high sugar content are prone to kidney stones.

It is because you don't eat well in the morning, so if you want to be healthy, you need to eat well in the morning.

There are many stones that affect women, which are the result of a variety of comprehensive effects, mainly age, race, genetic environment, eating habits and occupations have a great impact on the formation of stones, metabolic abnormalities of the body, obstruction of the urinary tract, infection, the use of foreign bodies and drugs are common in the formation of stones, and the final embodiment is the oversaturation of solute components in the urine, which is insoluble and crystallized, and precipitates into stones due to long-term accumulation. Kidney stones, which are stones of the urinary system, are mainly related to dietary life, and the specific situation mainly depends on the size and location of the stones.

The root cause of kidney stones is mainly due to the precipitation of crystalline substances in the urine to form small crystals after the urine is concentrated, and the crystals gradually increase and form stones. It has a certain relationship with our usual drinking water, diet, living habits, living environment and certain diseases. For example, people who have been in a high temperature environment for a long time and drink too little water can easily lead to concentrated urine and induce stone formation.

Secondly, long-term consumption of a large amount of calcium, oxalic acid content is relatively high, which is easy to lead to stone formation. For example, long-term consumption of milk, soy products, spinach, celery, etc., can easily induce the formation of stones. In addition, people with hyperuricemia are prone to the formation of uric acid stones.

Secondly, people with hyperparathyroidism are also a high-risk factor for stone formation. Secondly, it can also be seen in diseases of the urinary system itself, such as stricture of the ureters, which causes fluid accumulation in the kidneys, or recurrent infections of the kidneys, which can also easily lead to the appearance of kidney stones. We should pay attention to drinking more water, urinating frequently, and exercising more, which is conducive to reducing the formation of stones.

There are kidney stones, which can be divided into calcium oxalate stones, urate stones, calcium carbonate stones, and cystine stones related to genetic factors according to their composition. Causes of stones include abnormal metabolism of oxalic acid, uric acid, cystine, etc., too little water intake, abnormal urinary tract development, urinary tract infection, hyperparathyroidism, etc. Hello, according to the description of your condition, it is recommended that you need to go to the urology department of the hospital to have a look, it is best to do an analysis of the components of the stones, and check it.

1.Poor lifestyle habits, sitting for a long time, not liking to be active, drinking less water or holding urine. 2.

Metabolic abnormalities in the body, such as hyperglycemia, hyperthyroidism, and unreasonable diet. 3.Urinary tract obstruction, infections, and the effects of medications.

In addition to these reasons and environmental factors, it also has a lot to do with genetics and gender.

Hello, the formation process of kidney stones is caused by certain factors to increase the concentration of crystalline substances in the urine or reduce the solubility, in a supersaturated state, precipitation crystals and local growth, aggregation, and finally the formation of stones, in this process, the formation of the supersaturated state of urine crystalloid substances and the decrease in the content of inhibitors of crystal formation in the urine are the two most important factors, the formation of supersaturated state is seen in too little urine, the absolute excretion of certain substances in the urine is excessive, such as calcium, oxalic acid, uric acid, cystine and phosphate, etc.; Changes in urine pH: uric acid solubility decreases when urine pH decreases (<; When urine pH increases, the solubility of calcium phosphate, magnesium ammonia phosphate and sodium urate decreases; The change of urine pH has little effect on calcium oxalate saturation, sometimes the supersaturated state is transient, which can be caused by a decrease in urine output in a short period of time or a transient increase in the urine output of some substances after meals, so the measurement of 24-hour urine output and urine output of some substances can not help judge whether there is a transient supersaturation state, and the inhibitors of crystal formation in urine are reduced Normal urine contains certain substances that can inhibit the formation and growth of crystals, such as pyrophosphate inhibiting the formation of calcium phosphate crystals; Mucin and citrate inhibit the formation of calcium oxalate crystals, and stones will be formed when such substances are reduced in the urine, nucleation Homogeneous nucleation refers to the crystallization of a crystal, taking calcium oxalate as an example, when there is a supersaturated state, these two ions form crystals, the higher the ion concentration, the more crystals and the larger, the ions on the surface of the smaller crystals continue to fall off, and the research suggests that only when the crystals containing more than 100 ions have enough affinity to make the ions on the surface of the crystal not fall off, and the crystals can continue to grow, At this time, the required ion concentration is lower than when the crystals are just formed, heteronucleation refers to the fact that if the shape of the two crystals is similar, one crystal can be used as the core to promote the aggregation of another crystal on its surface, such as sodium urate crystals can promote the formation and growth of calcium oxalate crystals, and if the crystals in the urine are formed, if they stay in the local growth, it is conducive to the development of stones, many crystals and small stones can be flushed out of the body by urine, and when some factors such as local stenosis, obstruction, etc., cause the urine flow to be blocked or slow, it is conducive to the formation of stones.
