Nitrites in the urine treatment with folk remedies. The presence of nitrite in the urine: what does this mean? Causes and treatment of high concentration of chemical compounds in Urin. Causes of child detection
Present in Urine nitrates are considered the relative norm due to the abundance in the daily diet of food additives, the use of products, subjected to gene mutation.
If at this moment the growth of pathogenic microorganisms is activated in the intestines, there are special enzymes from the bladder, which converts these chemical compounds into nitrites, which are dangerous to the body.
The formation of nitrite in Urin comes from nitrates. Both refers to nitrogen compounds. The last of them are concentrated in vegetables, berries, fruits, falling into the urinary system through blood.
Compounds are filtered off by the kidneys and with time fall into the bladder, accumulating in it. This is facilitated by pathogenic microorganisms present there. When a person is completely healthy, its urine should not contain nitrites just like bacterial cells. If the compounds are detected, the body suffers from excess bacteria in the urinary tract.
What are the reasons for the appearance of nitrites in Urin?
They accumulate in the internal organs after receiving food vegetable origin, which was previously processed by chemical fertilizers - growth amplifiers.
First, nitrates penetrate into the body. In small quantities, this is considered the norm. Then they absorbed into blood And transported by vessels in the kidneys. Passing the cleaning process, they go into the bladder. Mixing with bacteria nitrates become nitrites. The formed nitrogen salts in Urine fall into the sediment. Intensifying the process of their formation can be causative agents of infectious diseases. This is especially true of intestinal sticks.
If antibiotics or the immune system were taken earlier, dysbacteriosis could develop, preparing favorable soil for microbes and harmful chemical compounds.
The appearance of nitrite in infants
Their high concentration in the children's urine is explained by the fact that it is not always possible to properly implement urinas for laboratory research. And it is recommended to deliver it as soon as possible were not false.
The process of the fence is complicated by the fact that the infants do not very much approve parental efforts to adjust the urinary and attempt to provoke urination. At the same time, there is a lot of time on the procedure, and microbes appear more chances to get into Urin through the hands of an adult or children's skin.
Opportunities for careful conducting hygienic procedures of the urine channel during this period are less, therefore, before reaching a one-year-old age, the boys may have an inflammatory process, agrowing with extreme flesh. Hence the bacteria in the urine, a false positive result of the tests. But most often the bladder becomes the place of reproduction of pathogenic microorganisms after the defeat of its infections.
Causes of child detection
Nitrite getting into urine in childhood occurs for various reasons:
- When using chemical fertilizers, activating the growth and ripening of vegetable crops. The elements are deposited in the fruits and then when they are eaten, penetrate the child's stomach. In the digestive tract under the influence of bacterial cells They change their molecular structure, there are their transformation into nitrites. They fall out in the process of responding to other elements and concentrated in Urin.
- Developing inflammation of the kidneys, intestines, external genital organs, bladder.
- The reaction to the use of diapers when the kidneys have to rebuild its work due to the greenhouse effect created by airproof hygiene facilities.
If they are found in men
The development of pathology is usually associated with inflammatory processes In the urethra, prostate gland or outdoor genital organs. Then there is a rapid increase in the number of pathogenic microorganisms, which increase the concentration of nitrites in the urinary system.
When the upper urinary paths are affected, it represents the greatest danger, because it is much more difficult to deal with such diseases than with the rest. It is important here in time to pay attention to the state of health in order to immediately begin treatment. Recommended at least once a year contain preventive inspection and take urine and blood tests.
Chemical compounds in the urine in women
They appear with diabetes disease. The accumulation of sugar in the body creates a productive nutrient medium for breeding bacteria. The formation of nitrites becomes a consequence of the interaction of nitrates with enterococci, intestinal wand, staphylococci and other pathogenic microorganisms.
The presence of harmful chemical compounds in Urin indicates the beginning of the pathological process. Disease pathogens can be localized in the lower or top urinary trait. This leads to a central or urethriter. Typically, the presence of nitrites is noticed after the manifestation of the corresponding symptoms - pain in the lower part of the abdomen, discomfort when urination, feverish state or chills.
During pregnancy
Not in vain before each inspection in the female consultation it is necessary to pass urine analysis. Only so you can diagnose unwanted changes in the body, including the appearance of nitrites. Their presence can lead to the following problems:
- development intrauterine infection;
- hypertensive crisis;
- violation of metabolism;
- the birth of premature babe.
In order to prevent further spread of pathology, it is necessary to stop bothering with stressful states, take vitamins, not to transfer and monitor the hygiene of the genitals.
Take care of your health on time, and nitrites in the urine will no longer cause concern.
How to treat pathology?
Starting therapeutic therapy is better with the normalization of the power mode, which has a direct impact on health. If possible, vegetable products are chosen from those producers in which you are confident, or grow them yourself. Boil vegetables or bake.
Eat more milk, cottage cheese, low-fat sour cream. The meat is needed in boiled form, giving preference to a poultry.
After visiting a medical institution will have to put the course of antibioticsVitamins. So you can prevent the dissemination of infection and stop the inflammatory process. To remove nitritis from the body, you will need to drink more purified water. Treatment implies a refusal of time from sexual life so as not to provoke further reproduction of microbes.
Sometimes with a general analysis of urine, we see the conclusion that nitrites were found in it. What is nitrites and what do they indicate? What do they differ from nitrates? What can affect the test results? Let's try to figure out these questions.
What is nitrites in the urine?
Nitrite is a salt of nitrogen acid. Normally they are not found in urine analysis in any quantities. If they are present, then it is a presence in the urinary tract bacteria.
However, other nitrogen compounds are nitrates for urine. They come there with some vegetable products that fell in the process of growing.
Nitrites are converted from nitrates as a result of the vital activity of some bacteria that can cause infectious damage to urinary tract, namely, salmonella and intestinal wand.
For this reason, nitrites are considered indicator of the inflammatory process in the urinary system.
The result of the analysis when nitrites were found in the urine, reveals hidden and obvious diseases of the selection system. Advanced parameters such as:
- Color, urine density.
- Acidness level.
- The presence of leukocytes, protein, blood and other signs of inflammation.
There is a biochemical express test to determine directly nitrites. It shows only their presence. However, this study does not replace overall analysis of urine and other laboratory studies.
Only in their conduct you can determine the localization of the inflammatory process.

Nitrites found in the urine: what does this mean?
Nitrites in the urine are determined in 8% of cases in chronic form of pyelonephritis, despite the fact that the disease in 30% of cases proceeds asymptomatic.
Usually, the pyelonephritis is detected protein, nitrites in the urine, leukocytes, red blood cells (less specific feature than the detection of leukocytes in large quantities) and other signs of inflammation. Since this disease is most often asymptomatic, and delay in the diagnosis and start of treatment can lead to severe pathologies, including renal failure, this test has a serious diagnostic value.
Especially relevant, it becomes for people from the risk group on pyelonephritis, which can produce it even at home (a domestic test strip is sold at the pharmacy).
At what other diseases are nitrites in the urine are positive? When cystitis, which is inflammation of the bladder mucosa, the test demonstrates the presence of these chemical compounds.
Especially often, women suffer from this disease - this is approximately the 5th patient. They predispose to the development of cystitis - improper nutrition, stress and lack of vitamins. However, the main reason is an infectious agent.
In his role, there is most often an intestinal wand. It is an additional source of formation of nitrites in the urine (in addition to the main path). Therefore, with a given disease, the diagnostic value of the nitrite test is high.
Intestinal wand acts as a microbial agent not only with cystitis, but also with pyelonephritis (inflammatory damage to the kidney laughter). In the urinary roads it penetrates the urogen path, primaryly lying in the rectum.
In this division of the large intestine, it is a normal inhabitant and does not cause the development of pathology. Initiation of pyelonephritis often accompanies a violation of the outflow of urine from the kidneys. Accompanied by the disease with such symptoms:
- Temperature can increase to 40 ° C.
- Signs of intoxication - nausea, vomiting, increased sweating.
- Painfulness in the renal projection on the lumbar region.
Often pyelonephritis is a complication of cystitis, when bacteria from the bladder fall further. Treatment of both diseases should conduct a doctor. In case, there are potential risk of dangerous complications, especially the kidney abscess, sepsis, etc.
Inflammation of the urethra, or urethritis, is diagnosed in women and men. It is most often considered as a complication of genital infections occurring in latent form. The symptoms of urethritis are:
- Burning and pain manifested during urination;
- Frequent urge to urination characterized by soreness;
- Appearance of secretions on underwear;
- Pain during sexual intercourse in men;
- Change the smell and urine color.
Incorrect or untimely treatment of urethritis can lead to surgical intervention. Indications are dictated by developing complications.
Difficult for diagnosis due to a lubricated clinical picture is the inflammation of the ureter. It is accompanied by some features of the blade:
- Turbidity;
- The presence of blood and pus;
- The presence of fibrin films (but not in all cases);
It is important that in suspected this disease, a general urine analysis is surrendered, nitrites are found in large quantities. It helps to establish a true diagnosis.
Is there a difference when nitrites appear in the urine in a woman and a man?
The urinary system of men and women works approximately the same, the difference lies in the structure of the urethra. Since women are shorter and wider, it creates the most favorable conditions for the penetration of causal microorganisms.
Therefore, the material obtained for the study has a large bacterial dissemination than men. More bacteria - more nitrogenous compounds produced by them.
For this reason, nitrite in the urine in a woman is always higher than in men. For people of different sexuality, there are permissible reference values \u200b\u200bto diagnose the rate or pathology.
As in adult and in children's analysis, nitrite should not be. A positive result indirectly indicates bacteriuria. The probability of a false positive result is extremely small, and a false-negative result is found quite often.
The latter means that despite the presence of bacteria in large quantities, the nitrites in the urine are not defined. In the study of the urine, a child is distinguished 2 common causes of a false negative result:
- Gram-positive and some other bacteria do not have special enzymes that are responsible for recycling nitrates in nitrites.
- Watering not to be in the bladder 4 hours and more than the sample fence (at a less time it does not have time to pass the enzymatic process).
The second item is particularly hard to implement in the event of a urine take to analyze in infants, as they write quite often. In addition, in order to avoid a false-negative test on the content of bacteria, basic rules for the analysis of the child's analysis should be performed. It:
- Careful toilet of external genital organs during sample fence.
- Taking urine using a special collection container, which can be purchased at the pharmacy.
- Storage is not in a girlish bank, but in a special sterile container.
- Delivery to the sample laboratory is no more than 2 hours, as a last resort for 4 after it is received.
- Restriction of fluid intake on the eve so that the urine is as concentrated as possible.
Nitrites found in the urine of the child - what does this parameter mean for his health? What to do in this case? First of all, do not panic and re-pass the analysis to eliminate the false positive result.
It is necessary to adhere to all the rules for passing the urine analysis (discussed above). If repeated analysis again indicates a bacterial infection, you need to contact the pediatrician for further examination.
Parallel requires adjustment of the child's nutrition. It is necessary to abate the use of oily, and emphasis on dairy products and dietary types of meat, for example, chicken or turkey.
A protein diet is prescribed, consuming vegetables and complex carbohydrates. However, in the case of children under 5 years old, it is impossible to exclude use and simple carbohydrates due to the possibility of the occurrence of another alarming symptom - the presence of acetone in the urine.
In addition to the intestinal sticks, the detected nitrities indicate the presence of staphylococci and enterococci. They are able to cause severe infectious damage to the body.
If the number of nitrites in the urine far exceeds the norm, the bacteriological study of urine is necessarily performed. When identifying pathogenic microbes in elevated credits, the course of antibiotics is minimum for at least 7 days.
- The revealed bacteriuria does not always lead to clinical symptoms - this is its danger.
Nitrites during pregnancy - is it dangerous?
If nitrites are found in the urine in pregnant women, doctors are almost immediately taking alarm. Any diseases of the genitourinary system during this period are associated with huge risks, especially the miscarriage, intrauterine infection and preeclampsia.
With the last pathology, blood pressure is strongly rising. This is capable of impairing blood circulation from the fetus and a deadly dangerous pathology of a woman - eclampsia.
Preeclampsia is put in the presence of 2 basic factors: protein in the urine, increased blood pressure. Pronounced edema are an additional criterion and do not always indicate this pathology.
Pregnant women regularly appointed urine analysis. But it can not always reveal the inflammatory process. In this regard, the nitrite test is a subsidiary method of diagnosis.
Other urine analysis options associated with nitrites
An increase in this amount indicates the presence of an inflammatory state or a violation of urine collection techniques. When they identify them together with nitrites, the likelihood of a diagnosis of an inflammatory nature increases.
The combination of protein + nitrites indicates the likelihood of glomerulonephritis or pyelonephritis. However, this diagnostic reception is rarely used, because It turns out to be positive no more than 5% of cases in the presence of pathologies.
Tests to determine nitrites in the urine at home
It is possible to determine the presence in the urine of nitrites using a special test strip. Such strips without recipe are purchased almost in any pharmacy. It is recommended to periodically carry out similar tests to all and adults and children over 4 years old. Especially relevant their use in childhood, when it is difficult to describe the existing clinical symptoms, and the diagnosis is difficult.
Test strips contain a special reagent called the modified GISS reagent. It reacts with nitrites, staining strip. Depending on the intensity of the color, by analogy with the determination of the level of the acidity of the medium, one can approximately be on the eye to determine the content of nitrites in the urine.
- Additionally, such tests can determine protein and sugar.
Since the concentration of nitrite in the urine depends on many factors, including types of bacteria, the accuracy of this test does not exceed 50-70%. Therefore, it does not replace the professional laboratory diagnostics, but only serves as a reason for its holding.
An increased concentration of ascorbic acid in the urine can affect the result of the test. Therefore, to take tests and carry out such tests using a test strip need not earlier than 12 hours after taking the last tablet Vitamin C.
The false positive result can be obtained using some drugs, in particular, the Fenazopyridine. Test is recommended not earlier than 3-4 days after the end of therapy with antibiotics.
Nitrites in the urine are not a specific indicator of bacteriuria. Their absence also should not be regarded as a reliable criterion for the absence of infection.
- Any suspicion of bacterial inflammation requires a thorough laboratory research.
The presence of nitrites in the urine is sometimes equal to normal, given the quality of consumed modern food (products contain many food additives, animals are grown by accelerated methods). Various diseases of the urinary system provoke the allocation of a special enzyme, under the influence of which nitrates are transformed into nitrites (they are easy to detect in the patient's urine during overall analysis of urin).
The infectious hearth may be in any separation system. Pathology in the upper duty station of the urinary system is worse than diagnosing, most patients turn to the doctor only after the appearance of sharp pain in the lower back, the presence of fever, hematuria. The illness of the lower department is easier to detect, thanks to pronounced symptoms immediately after infection.
general information
Nitrites are formed from nitrates (various nitrogen compounds). Nitrates are rich in vegetable food, fall into urin of human blood. Substances are filtered by the kidneys, in small quantities are delayed in the bladder.
The presence of pathogenic microorganisms on the path of nitrites to the exit leads to their accumulation. Nitrites should not be present in the urine of man, Since there should be no pathoral microorganisms there either. Given this fact, nitrites in Urine Patient always indicate the active life of microbes in the urinary system.
Causes of detection in adults
Nitrite in both sexes are the same, when studying analyzes, only the degree of purity of the biomaterial is taken into account (based on the fact that the urethra of men is thinner and shorter than that of the ladies). The contamination of the obtained sample in the laboratory is of great importance (during the storage or long-term transportation of the bacteria feed on nitrites, reducing their number in Urin, which distorts the results of the analysis).
By frequent reasons for the appearance of nitrites in the urine in excellent gender include:
- Various etiology.
Men suffer from pathology less often than women, but completely different reasons:
- prostate adenoma, very rarely -;
- inflammatory process in the ureter (often formed against the background of infection to infection);
Determine the exact cause of the presence of nitrites in Urine is only a physician after a number of analyzes. Alone to treat negative symptoms is categorically prohibited!
Nitrit in urine in children
Nitrites in urine of kids are observed during various infectious diseases not only in diseases of the excretory system. Laboratory analysis can show the presence of a large number of leukocytes, nitrites, erythrocytes, but bacteria may be absent. This does not mean that the analysis does not indicate different pathologies. Only an experienced pediatrician will help to deliver the correct diagnosis. Self trying to treat crumb strictly forbidden.
Deviation of indicators during pregnancy
Ladies in the position are vulnerable to various bacteria. If a pregnant patient has nitrites in Urin, doctors immediately beat the alarm. Any diseases of the urinary sphere during this period threaten the normal development of the baby, in general, to wear crumbs. An intrauterine infection is dangerous not only for the life of the child, but also can lead to a fatal outcome for a woman.
It's important to know! Pregnant ladies regularly assign urine analysis. But not always the study helps to identify the inflammatory process in the early stages. For this reason, the ladies in the Regulations are recommended to regularly test the netritis test in Urin at home.
Indications and contraindications for analysis
Which shows the presence or absence of nitrites, is prescribed in almost all diseases (not only the urinary system) during control over the treatment of pathologies, also screening research. Urin analysis is an effective method for the diagnosis of various pathologies of the system of the human system.
An important role is played by other indicators, often with nitrites find out the level. They are white blood tales, perform a protective function. Their norm should not exceed 1-4, other indicators indicate inflammatory processes or the fact that the biomaterial was collected incorrectly. There are no contraindications to the analysis of urin nitrites in the patient, there are only rules for collecting and preparing for research to obtain accurate results.
How to prepare for the surrender
Specialist advice will help reliable results:
- before renting Urin, thoroughly wash outdoor genitals, do not use antiseptic tools, they can kill the existing bacteria, showing not a reliable result;
- purchase the sterile container for the collection of urine, to apply a canon jar for this purpose is not advisable;
- refuse the admission of alcohol, potent drugs on the eve;
- sex acts 24 hours before the delivery of urines is prohibited;
- vitamin C reduces the number of nitrites in the urine, so it is not recommended to eat products and medicines rich in this substance three days before the intended delivery of urins;
- the analysis is not recommended to be carried out 10 days before treatment with antibiotics and the same amount of time after;
- fenazopyridine (used for therapy of the alerts of the excretory system) distorts the level of nitrites in Urin, so during the use of drugs on it, it is not advisable to conduct urine analysis;
- collect Urin, which was in the bladder at least 4 hours. Under such criteria, the morning urine falls, it is precisely it is collected for analyzing nitrite.
After the proper collection of urine immediately take it to the medical institution. Under the action of air, sunlight, the liquid changes its chemical composition, distorting the results of the tests. Studies of urine patients are conducted in special laboratories, the results give a doctor who decrypts and assigns the necessary course of therapy.
In infancy, it is often observed in the analysis of urin "Mix-bacteria". This state is usually emerging in the womb of the mother, which is caused by the disease that the mother suffers. Also, the situation is observed with the wrong fence of the material. Make all manipulations with crumb trouble. The child does not realize what a urination is, microbes from the hands of a baby, mother, the skin of other parts of the body fall into Urim with ease.
The boys often have an inflammatory process of extreme flesh, which increases the number of bacteria in the urine. In view of this state of affairs, the collection of biomaterial doctors is recommended to conduct in medical institutions, then immediately refer to urine for analysis. The right approach to the collection of urins is the key to the exact results.

Special Nitrite Test
The best way to avoid various complications of diseases of the excretory system is timely diagnosis of the problem. The pharmacological industry produces a special home test for nitrites, it is not necessary to go to the clinic to conduct urine research. The test is a litmus strip that react to nitrites in Urin.
It is very easy to use it - dip the strip in a fresh portion of Urin, wait a few minutes, the result obtained compare with the scale that is attached to the test. It is not necessary to absolutely trust this method of diagnostics, many different factors affect its result. View of bacteria, their sensitivity to antibiotics will not be able to learn, but you will receive information about whether to contact the physician and conduct a laboratory study.
An important minus test strip - it reacts only to a certain type of bacteria, ignoring others. The rest of the express test shows excellent results, suitable for home use, especially to prevent recurrence of chronic pathologies.
What indicators indicate
Nitrites in Urine Patients in 8% of the total mass of cases indicate the chronic flow of pyelonephritis, about 30% of pathology proceeds asymptomatic. The cystitis accounts for the lion's share of the increased number of nitrites in the urine of patients. Each fifth woman at least once in his life came across this problem. Pathology is accompanied by pain and, increasing body temperature. A complex clinical picture in the inflammation of the ureter, it meets only 5% of the total mass of patients.
The exact diagnosis will be delivered by a doctor independently starting therapy is categorically prohibited!
Specific therapy depends on the diagnosed disease. In most cases, the patient is prescribed antibiotics that destroy pathogenic microorganisms, antispasmodics that bind unpleasant sensations. Further treatment plan varies, given the degree of destruction of the excretory system, the overall state of the victim. During the tooling of the baby, the potent means are prohibited for receiving, so the lady is prescribed other medicines. Only after the birth of crumbs is allowed to carry out full therapy.
Nitrites in the urine - an unpleasant phenomenon indicating the course of the inflammatory process in the urinary sphere. Follow the recommendations of the doctor, give up home treatment.
