Urolithiasis disease. Kidney uric acid stones are linked to malnutrition

One of the types of urolithiasis is urate kidney stones. This anomaly is the 2nd most common in humans. As a rule, it is recorded in the period from 20 to 55 years. Uric acid stones in elderly people are detected in the bladder, and in young people - in the renal organs and ureters. The formation of calculi that are not detected in time are dangerous with serious complications.

General information

Pathologies with metabolic disorders, as a result of which urate stones and other insoluble compounds in the renal organs are formed, are called urolithiasis. The formation of urates is typical for a strong half of humanity. Urate stones are colored yellow-brown with a relatively smooth structure. The kidney, ureter and ureter are the organs in which uric acid stones form. A dangerous deterioration is the transformation of urate stones into coral-shaped ones, which is fraught with diseases such as pyelonephritis and chronic renal failure.

Causes of uric acid kidney stones


An insufficient amount of B vitamins can provoke an anomaly.

According to experts, the emergence of a pathological process in the form of the formation of urate stones in the body is facilitated by various reasons, acting in combination or separately, they include:

  • Genetic predisposition. Urolithiasis is inherited, as an example, high levels of calcium in the body (calcium is building material for calculi in most cases).
  • An increase in salt concentration due to a malfunction of metabolic processes. This will lead to disruptions in the natural balance of microelements, a salt precipitate will appear, from which stones will begin to form.
  • Monotonous nutrition can serve as a factor in the development of stone formations.
  • Place of residence of the person. There are geographical places in which cases of urolithiasis are more often recorded. To avoid this, the body should be kept hydrated.
  • The specific composition of the water consumed can influence the progression of the disease.
  • Insufficient amount of B vitamins.
  • Favorable conditions for the development of the disease - hard work; passive lifestyle; bad habits, fasting.
  • The use of a large amount of analgesic drugs.
  • Acid reaction of urine. Acidic indicators can be identified using specialized rapid tests. Indicators are normally considered from 6.0 to 7.0.
  • Excessive content of uric acid salts in urine. Salts are the end product of protein metabolism in the body, which is always present in urine. To change to an alkaline reaction, you should eat a lot of vegetables, fruits and dairy products.

Symptoms


Nausea and urge to vomit - possible symptoms the presence of urate stones in the body.

The main danger in the formation of stones is that long time no symptoms appear. In the later stages, the main symptom of the presence of urate stones in the body is renal colic and its characteristic manifestations:

  • sharp pains in the lumbar region;
  • painful sensations spread to all organs of the genitourinary system (from the bladder to the adrenal gland);
  • a painful attack cannot be stopped;
  • the presence of tremors in the body;
  • nausea and urge to vomit;
  • excessive gassing;
  • pain when urinating;
  • gout;
  • visual deviations from the parameters in urine (turbidity, sandy sediment, bloody spots).

An increase in body temperature is an alarming symptom that speaks of an incipient inflammatory process in the renal organs. The development of renal colic occurs during obstruction of calculus in the normal outflow of urine. At the first sensory or visual changes in the body, you should consult a specialist, the pathology detected in time is corrected much faster than a neglected state.

Diagnostics


For staging accurate diagnosis it is necessary to undergo examination.

Men are more prone to the formation of urate stones in the body. They associate this with the fact that the male sex has a more pronounced preference for meat and dishes from it. The resulting excess of uric acid provokes the formation of urate calculi and gout. However, women are more likely to suffer a severe form of urolithiasis, namely, large coral-shaped stones. During the diagnosis and selection of effective therapy, one should take into account the existence of chronic diseases, namely coronary heart disease, diabetes mellitus, obesity, gout and hypertension. To make an accurate diagnosis, an examination is prescribed, consisting of:

  • general blood test;
  • deep laboratory studies of urine;
  • urography (overview and excretory);
  • ultrasound examination of the urinary system;
  • spiral computed tomography (CT);
  • magnetic resonance imaging (MRI);
  • contrast fluoroscopy (conventional X-ray is not effective).

Pathology treatment

General principles of conservative treatment

The specificity of the uncomplicated degree of pathology in light dissolutions of urate formations. Conservative methods contribute to the development of a favorable outcome. Uric acid stones dissolve under the influence of the consumption of a large volume of liquid, which triggers a change - the acidic state is converted to alkaline. With this therapy, an important role is played by nutrition, namely, a large consumption of plant and dairy products is introduced into the human diet and the intake of alkaline mineral water. If such measures are not able to dissolve urinary salts, then treatment with medication or surgery is prescribed.

Drug therapy


Medicines can help relieve pain and inflammation.

Treatment of urate kidney stones with drugs is aimed at:

  • removal of pain attacks;
  • correction of protein metabolism;
  • an increase in the rate of formation and volumes of urine;
  • removal of inflammatory processes (if any).

To achieve these goals, they resort to antispasmodic drugs to relieve muscle tension in the urinary tract; they turn to uricostatic drugs in case of violation of the exchange of purines; to increase the volume of urine, diuretics are used and antibiotic therapy is prescribed for concomitant inflammatory processes.

Diet for calculi

Adherence to the rules of a special dietary diet is the main measure in the therapy of urate formation, regardless of what treatment is prescribed by the doctor. The diet promotes the dissolution of urate formations. Food should be taken in fractional portions in the amount of 4-6 meals per day. It is imperative to include such foods in the diet:

  • legumes;
  • bakery products (especially from the highest wheat varieties);
  • spinach;
  • sorrel greens;
  • luke;
  • oatmeal;
  • fish and seafood;
  • spices;
  • chocolate products;
  • hot drinks (cocoa, tea, coffee);
  • table salt.

Foods completely excluded from food:

  • fatty meats and their offal;
  • rich fish or meat broths;
  • alcoholic drinks (beer, red wine).

Method of administration and dosage. Inside, 0.05-0.1 g 3-4 times a day after meals for 1-3 weeks.

To facilitate the removal of stones from the urinary tract, it is recommended to prescribe a large amount of fluid to the patient at the same time as taking Avisan. In the absence of contraindications from the outside of cardio-vascular system and the kidneys, the patient drinks 1.5-2 liters of water or tea within 2-3 hours. This technique is repeated after a few days. The patient should be under medical supervision.

Almost every second patient with a diagnosis of urolithiasis is faced with the situation when urate stones are formed in the kidneys.

The urate calculi are round in shape, have a smooth surface, and the color varies from yellow to brown.

The risk group includes people of the age category from 20 to 55 years. In elderly patients, urates are diagnosed in the bladder, and in young people - in the kidneys and ureter.

The danger of uric acid stones is the development of complications if a person does not seek qualified help for a long time.

Three factors can most often provoke the formation of urate kidney stones.

Formation of urate stones

1. High acidity of urine. In order to regularly measure the acidity level of urine, experts advise using test strips or a medical device - a hand-held pH meter at home.

This technique allows you to effectively control and make changes to the nutritional system and the course of therapy. Normal values \u200b\u200brange from 6.0-7.0 pH. During the day, the indicator changes from more acidic (up to 6.4 pH) to more alkaline (from 6.4 pH). If the level of urine acidity is above 5.5 pH, you need to pay attention to the diet. It is best to measure acidity twice: an hour before meals and a few hours after.

If urolithiasis is suspected, urine acidity should be measured twice a week, three times a day.

2. Uraturia - increased content of uric acid salts in urine. If an acidic urine reaction is recorded, this is not a sufficient reason for the formation of urates. Stones appear with a complex of factors: high acidity and the presence of uric acid salts. Salts of this category are present in the body of every person.

Formation of uric acid in urine

A favorable condition for their precipitation and the formation of urates is urine acidity below 5.0 pH. To change the reaction of urine from acidic to alkaline, it is enough to add a variety of dairy products to the diet. But the excess amount of meat dishes on the menu contributes to the formation of urates. That is why urate stones are diagnosed in men much more often than in women.

You can neutralize the effect of meat products with vegetables and herbs.

3. Low rate of urine formation. If urine in the body does not form quickly enough, its concentration exceeds the permissible norm, and this can provoke the formation of urates. In order to speed up the process of urination, you must drink plenty of water. However, it must be borne in mind that excessive fluid intake is contraindicated in patients with pathologies of the cardiovascular system.

Reasons for the increase in urate formation

Other factors contributing to the formation of urates:

- lack of vitamin B;

- a long course of treatment with analgesics;

- improper nutrition;

- sedentary lifestyle.

In severe cases, urates transform into dangerous coral-shaped stones, which in turn cause pyelonephritis and even kidney failure.

Symptoms of the disease

Urolithiasis, in spite of the chemical composition of calculi, takes a long time without pronounced symptoms. As a rule, the patient learns about the disease only when renal colic begins.

Blockage of the ureter with a stone - renal colic

  • discomfort in the lumbar region, manifested on one side;
  • discomfort spreads to the abdomen, bladder and genitals;
  • pain cannot be eliminated medicines, a person cannot find a comfortable position to relieve pain;
  • chills;
  • nausea and vomiting;
  • flatulence;
  • high body temperature (appears with an inflammatory process in the kidneys).

Renal colic occurs when calculus prevents the flow of urine from the body.

Diagnosis of pathology

To identify urolithiasis and establish the chemical composition of calculi, a set of diagnostic measures is used:

  • ultrasound examination of the kidneys;
  • detailed analysis of urine and blood;
  • urography;
  • cT scan;
  • magnetic resonance imaging;
  • radiography of the kidneys using a contrast agent.

Standard X-ray examination does not provide an opportunity to detect urate stones.

Treatment

Considering the peculiarity of urates easily dissolve in water, as a rule, the treatment of urate kidney stones does not require procedures associated with penetration into the body.

Thus, it is possible to achieve complete dissolution of uric acid stones in the kidneys.

Also, a course of conservative therapy involves:

  • taking medicinal decoctions of medicinal herbs with a diuretic effect;
  • the appointment of a therapeutic diet based on dairy products, fresh vegetables and the complete absence of meat and offal;
  • the drink must be alkaline.

Surely, many of you have heard of such a disease as gout. But not everyone is aware that it occurs due to deposits of uric acid in the joints. Pathogenesis of increased blood urate, risk factors and treatment.

In this article, you will learn all about the causes of urolithiasis in women. Treatment and diet for urolithiasis.

Therapeutic diet for urates

Therapeutic diet for urate kidney stones is not just one of the stages of therapy, but a way of life. There are three categories of products: prohibited, conditionally allowed, and healthy.

Diet with uric acid stones

The basic principle for dividing food is the amount of animal protein in the food. The higher the protein level in a food, the more dangerous it is for a patient with kidney urate.

List of permitted food items:

  • fresh vegetables, berries and fruits;
  • milk products;
  • cereals;
  • pasta;
  • coarse bread;
  • vegetable, fruit and berry juices;
  • compotes;
  • weak tea with lemon.

List of foods that need to be limited

  • bakery products made from wheat flour;
  • legumes;
  • spinach, sorrel and onions;
  • a fish;
  • chocolate;
  • spices;
  • spicy dishes;
  • salt;
  • strong tea.

List of Prohibited Foods

  • alcoholic beverages;
  • fatty meats;
  • offal: kidneys, liver, heart, lungs;
  • too saturated meat and fish broths;
  • animal fat;
  • canned and pickled foods;
  • mushrooms.

In addition, you should drink at least two and a half liters of any liquid.

Treatment with folk methods

Herbs are widely used in the treatment of urate stones, which have a diuretic and anti-inflammatory effect on the body. For this purpose, you can prepare decoctions and infusions of lingonberry leaves, horsetail, bearberry and, of course, half-burnt.

The benefits of lingonberry for the kidneys

Very often, such herbal medicine contributes to the complete dissolution or removal of stones from the body.

Disease prevention

Treatment of urate calculi involves the observance of preventive measures aimed at eliminating the likelihood of re-formation of urate.

  1. Drink as much as possible. The recommended daily volume of fluid for an adult is often one and a half liters. However, this volume is only enough to maintain the natural metabolic processes in the body. When it comes to high-quality flushing of the kidneys, elimination of toxins and toxins, ensuring filtration, this amount of water is not enough. Drink at least two and a half liters of liquid.
  2. Avoid hypothermia of the kidneys.
  3. Avoid the development of infectious diseases.
  4. Constantly adhere to a therapeutic diet.
  5. Exercise regularly.

Only strict adherence to all preventive measures guarantees full recovery, and also significantly reduces the risk of urate calculi formation and possible complications in the future.

The main cause of kidney stones - increased concentration of stone-forming salts in the urine. In turn, an increase in the concentration of salts in the urine may be a consequence of a long-term decrease in the daily volume of urine and / or excessive ingress of salts into the urine. Various reasons can cause decreased urine volume or an increase in the amount of salt in the body.

So, urine removes salts from the body, while the salts are in it in a dissolved state. With an increase in the concentration of salt in the urine, it can no longer completely dissolve and forms crystals. Over time, the crystals, connecting with each other, form calculi.

Note the fact that urine contains substances that prevent the formation of stones in the kidneys. These include magnesium, citrate, pyrophosphate, etc. What do these substances do? Firstly, they prevent the formation of crystals from salts, even though their concentration in urine is increased. Second, they can bind to crystals, preventing them from sticking to the urinary tract. A lack of these substances can also cause kidney stones.

Another reason for the formation of stones in the kidneys is change in urine acidity... For example, uric acid calculi appear faster in acidic urine, and calcium phosphate, on the contrary, in an alkaline environment.

Picture.The figure shows a primitive diagram showing the mechanism of stone formation. Both excessive ingestion of salts in the urine and a decrease in the volume of urine lead to the same thing, namely, an increase in the concentration of salts in the urine, their combination and precipitation.

inadequate fluid intake or vigorous exercise without adequate fluid replacement increases the risk of kidney stones. It is logically clear that hot climatic conditions can also predispose to the formation of calculi, since a hot dry climate contributes to dehydration due to increased sweating... Chronic impairment of the outflow of urine can be the cause of the formation of calculi in the kidneys. Kidney stones can also form due to urinary tract infections. Metabolic disorders, including congenital and acquired diseases, can lead to a change in the composition of urine towards an increase in concentration stone-forming salts.

Most often a person has four types of stones: calcium, urate, struvite (in other words, infectious) and cystine. Let's take a closer look at the reasons for the formation of certain types of kidney stones.

Picture.The figure shows stones located in the small and large cups of the kidney, the initial part of the ureter.

Calcium oxalate kidney stones are the most common type of calculus. Often, the cause of calcium stones is unknown. And this condition has the medical name of idiopathic nephrolithiasis. Most calculi appear as a result of dysregulation of calcium and oxalate metabolism. Moreover, in half of the cases, dysregulation is associated with genetic factors. Some of the causes of kidney stones are due to impaired digestion and the absorption of calcium and oxalate in the intestine.

Excessive calcium in the urine. This explains the formation of 70% of calcium stones. The following reasons can lead to an increase in urinary calcium:

  • Too much calcium is absorbed in the intestines. Don't assume this could be due to your increased calcium intake. Often, the increased calcium absorption is due to genetic factors, although in most cases the exact cause is not clear.
  • Leakage of calcium in the kidneys: In this case, there is a violation of the metabolism of minerals in the body, characterized by an excess of calcium in the urine.
  • Some defects in kidney function can be accompanied by metabolic disorders, while there is an increased sodium content in the urine, which in turn leads to an increase in calcium levels. Also, excess consumption of table salt can lead to increased levels of sodium and calcium in the urine.

Increased urinary oxalate. Oxalates, like calcium, are the most common component of kidney stones. Too high urinary oxalate is associated with stone formation in 60% of cases.

What leads to increased urinary oxalate?

  • An increased content of oxalate in urine can be a manifestation of congenital or genetic metabolic disorders.
  • In addition, a number of pathological processes and diseases can lead to a secondary increase in the level of oxalates in the urine: a lack of vitamin B6 in the body, short bowel syndrome, which develops after the removal of a significant part of the intestine or as a result of inflammatory bowel diseases. In addition, a diet rich in oxalates may contribute to excess buildup in urine.
  • Changes in hormone levels, in particular male sex hormones, can lead to impaired oxalate metabolism. An interesting fact is that the female sex hormones estrogens, on the contrary, reduce the risk of kidney stones. Estrogens prevent the development of calcium kidney stones by maintaining an alkaline urine reaction and high citrate levels.

Elevated blood calcium. Increased blood calcium can be caused by bone breakdown, accompanied by the release of large amounts of calcium into the bloodstream. This could be the result:

  • Disease of the parathyroid glands, characterized by their increased work, causes 5% of all cases of kidney stones. People with this condition have a twenty percent risk of kidney stones. In women, diseases of the parathyroid glands are more common than in men.
  • Prolonged immobility and immobilization, such as from trauma, can cause kidney stones.
  • Renal tubular acidosis is a disease accompanied by a change in the acidity of urine. At the same time, the level of calcium in the urine increases and the concentration of citrate decreases.

Low level citrate in urine... Citrate is a substance responsible for the elimination of calcium from the body. In addition, citrate prevents calcium ions from forming crystals and the formation of calculi. Low urinary citrate levels are one of the causes of calcium kidney stones. Also, a lack of citrate can increase the risk of urate calculi formation.

What could be the reason for the decrease in the concentration of citrates in the blood?

  • Renal tubular acidosis;
  • Lack of potassium and magnesium in the body;
  • Urinary tract infections;
  • Renal failure;
  • Chronic diarrhea, etc.

Also, a number of medications can increase the risk of kidney stones, for example, the antifungal drug amphotericin B, hormonal drugs, theophylline, vitamin D, etc.

Causes of uric acid kidney stones

Urate stones - These are calculi consisting of uric acid salts.

Where does uric acid come from in the body?

Purines are the source of uric acid formation in the body. Purines- these are vital and irreplaceable components of any cell in the body. They are a part of DNA, various enzymes, etc. A large amount of purines is found in protein foods, especially in protein of animal origin. When body tissues are destroyed or when protein foods are consumed, purines are released, which, under the action of a number of substances, are converted into uric acid. Normally, the human body contains a certain small amount uric acidbut too much can cause kidney stones.

A number of pathological conditions and diseases can cause the formation of urate calculi in the kidneys:

  • Gout. Uric acid kidney stones form in 25% of patients with gout. Gout is characterized by high levels of uric acid in the blood and the deposition of salt crystals in one or more joints.

Picture. The picture shows the big toe joint lesion and kidney stones, which is a manifestation of gout.

  • Diabetes. In people with type 2 diabetes, there is an increased content of uric acid salts in the urine, which is accompanied by the formation of calculi in the kidneys. Those. for the 18 million people around the world living with diabetes, the risk of urate formation is higher.
  • Kidney anomalies. Kidney disease, characterized by a decrease in ammonium production, can cause calculi.
  • Genetic Causes of Kidney Stones: Several genetic factors increase the risk of uric acid kidney stones.
  • As we have already mentioned, a lack of citrate in the urine can be an indirect cause of uric acid stones.
  • Excess consumption of foods rich in purines, namely animal proteins, is a common cause of kidney stones.

Less commonly, uric acid stones can be caused by:

  • Taking certain medications (chemotherapy drugs, diuretics, salicylates, etc.).
  • Alcohol abuse.
  • Chronic diarrhea.
  • Rare types of anemias (diseases involving the destruction of red blood cells) and treatment of tumor processes (lymphoma, myeloma or leukemia), accompanied by massive destruction of tumor cells. When cells are destroyed, purines are released into the blood, from which uric acid is formed. This may be the reason for the formation of urate calculi in the kidneys.
  • Lead poisoning, etc.

Please note that increased uric acid content in the urine can trigger the formation of calcium stones. Therefore, often in patients with uric stones, calcium calculi can be found.

Struvite stones also called infectious calculi, as they are formed as a result of infections of the urinary system caused by bacteria that can secrete a special enzyme. This enzyme increases the ammonium content in urine. Ammonium, in turn, forms crystals and forms struvite calculi. Women have twice the risk of developing infectious stones than men.

Causes of Other Kidney Stones

Less commonly, people may have xanthine, cystine, medicinal and other stones.

For example, cystine stones are formed due to genetic abnormalities. The genetic defect causes a violation of the transport of the amino acid cystine in the body, leading to its accumulation in the urine and the formation of calculi in the kidneys.

Xanthine stones may result from long-term treatment of gout with allopurinol.


Uric acid stones are formations that are easiest to dissolve with the help of drug therapy. The uric acid salts of which they are composed are effectively dissolved with the help of litholytic therapy preparations.


X-ray examination is not able to diagnose urate stones due to their low density, but they are clearly distinguishable on ultrasound. It is possible to determine the composition of the formation by examining it after surgical removal or independent exit from the urinary tract. It is possible to determine the composition of the stone in the body using diagnostic methods. If the pH of the urine deviates from the norm towards acidity, it is most likely a urate stone. Determine the exact density of the formation using computed tomography.

But CT scan is not necessary if there are the following signs:

    On ultrasound, the stone is visible;

    On x-ray, urate stone is not detected;

    Urine tests revealed a shift in pH towards acidic reaction.

If these signs coincide, it is worth trying to dissolve the stone. Most often, such formations occur in patients with impaired purine metabolism. For this reason, if urolithiasis is suspected, a study of the level of uric acid in the blood should be carried out.

Role of urine pH in dissolving urate stones

To dissolve urates, an alkaline drink is prescribed, which increases the level of acid-base balance. Citrate preparations are designed to convert urine from acidic to slightly acidic or alkaline. The dissolution of urate stones with the help of drug therapy takes from 2 months to six months.

To speed up this process, the following tactics are used - preliminary remote or contact endoscopic crushing of at least 2 cm in size, and subsequent dissolution of the remaining small fragments. Treatment is accompanied by plenty of drinking and adherence to a special diet.

Most often, patients seek medical help when the stone has moved from the place of its formation and moves from the kidney along the urinary tract. Movements are accompanied by acute pain due to renal colic, and the appearance of obstructive pyelonephritis. Since there is no time for a long process of dissolving a large stone, the stone is removed by any available method, and the remaining formations are then dissolved.

Dissolving urate stones with plain water

With an increased volume of fluid consumed, the pH of the urine shifts towards a decrease in acidity. As a result, the concentration of salts decreases and small urate formations dissolve. If the stone has a mixed composition, or a constant elevated level of urine pH cannot be maintained by the citrate preparations taken, then their further use does not make sense. If the treatment is successful, then citrate mixtures should be used further, but under the guidance of a urologist or nephrologist, since drugs for dissolving stones have pronounced side effects.

Note the important fact that alkalization of urine reliably dissolves only uric acid formations. Although it is possible to dissolve oxalate formations using citrate mixtures, in practice it is not so effective. As a rule, citrate preparations are taken for prophylaxis, after the crushing of calcium oxalate kidney stones.

Will lemon or cranberry juice dissolve urate stones?

No, these remedies are not capable of dissolving stones, lemon acid only minimizes the absorption of calcium in the gastrointestinal tract. Abuse of such recommendations can lead to stomach bleeding and other negative consequences up to.

Is it safe to drink diuretic herbs?

Uncontrolled intake of renal teas leads to dangerous consequences... The stone in the kidney, under their influence, can be moved at the most inopportune moment. As a result, an acute inflammatory process develops, the patient experiences acute pain in renal colic.


The patient is diagnosed with urolithiasis under the following conditions:

    The size of the stone is more than 0.5 cm;

    It has a dense structure;

    Ultrasound does not pass through the stone (there is an acoustic path).

In medical practice, the diagnosis of "sand in the kidneys" is not made. What is taken for "grains of sand" on an ultrasound is the inlaid papillae of the kidneys, blood vessels, or compacted fiber. Do not drink diuretics at the first suspicion of "kidney sand". An ultrasound should be done once every 6 months, determining the dynamics of changes in the renal structure and extraneous formations in it. If there is no growth of stones, most likely these are individual features of the structure of the kidney.

Diet for urate kidney stones

Diet food - an important component of the treatment of urolithiasis. It is prescribed taking into account the general condition of the patient, the presence of somatic diseases. So, for example, with cardiovascular disorders, it is required to limit the amount of fluid entering the body. Diabetes patients should adjust the recommended diet to suit their needs.

It is necessary to maintain a balance of substances that the body needs for normal functioning, and not to apply the diet for a long time. Otherwise, stones of a different composition will begin to form.

The basic principles of a diet in the presence of urate stones:

    Limitation of foods that provoke urolithiasis;

    The use of products that affect the change in urine response;

    An increase in the volume of fluid used to remove salt sediment.

For the therapeutic effect, products with a minimum of purines are recommended: bread, dishes from vegetables, fruits (with the exception of prohibited crops), dairy products, nuts, berries, cereals. Dishes from low-fat combs of meat and fish in boiled form are allowed, 1 egg per day, the use of butter or ghee.

Prohibited Products:

    Meat offal;

    Legumes, peanuts;

    Vegetables: cauliflower, sorrel, spinach;

    Fruits: raspberries, figs, cranberries;

  • Horseradish and mustard as a seasoning;

    Sweet pastries;

    Coffee, cocoa, hot chocolate;

    Refractory fats: beef, lamb, culinary;

    Canned food;

    Salty and spicy cheeses;

    Sausages.

With the patient's recovery, the diet is gradually adjusted, returning to the usual level.
