What could be the reason for the smell of urine from the mouth? In fact, there are a lot of them - according to this symptom alone it is difficult to determine what exactly is wrong with the human body.
The causes of the smell of urine from the mouth in a man, woman, child can be as follows:
- Sinusitis, rhinitis.
- Stomach infection.
- Chronic diseases of the renal system.
- Wrong diet.
- Uremia.
We will deal with these causes of the smell of urine from the mouth in more detail.
Rhinitis or sinusitis
Why is there such a foul odor? It's all about the bacteria that cause these infectious diseases. It is the products of their life that cause bad breath of urine.
In addition to this symptom, the patient may complain of nasal congestion. This condition is called sinusitis. Such a disease is an infectious inflammation of the hollow cavities in the nose.
But rhinitis and sinusitis are not always by their nature infectious diseases. They may be the result of any irritation of the nasal cavity or an allergic reaction. These conditions are often accompanied by an unpleasant smell of urine from the mouth, which indicates the development of acute inflammation.

With the permission of your doctor, you can turn to home treatment:
- Rinse the sinuses with special solutions.
- Inhalation of steam (inhalation) of medicinal decoctions.
- Drops based on honey, onions and other folk remedies.
Gastric infection
The smell of urine from the mouth in a child and an adult also often indicates the development of an infection that affects the gastrointestinal tract. The causative agent here is the bacterium Helicobacter pylori. According to statistics, it infected more than half of the world's population. But at the same time, the vast majority of people do not suffer from any symptoms. Including the strong smell of urine from the mouth.
Helicobacter pylori lives in the human stomach. For certain causes and effects, it can cause inflammation of the mucous membrane of the organ. And this already leads to peptic ulcer and even cancer of the stomach. The smell of urine from the mouth of a man, woman, child is one of the first signs of the onset of a pathological process.
In addition, the patient may note the following:
- Discomfort in the epistragal zone.
- Pain in the stomach.
- Poor appetite.
- Bloating.
- The dark color of the chair.
- Nausea, vomiting.
- Weight loss.

- The course of antibiotic drugs.
- Proton pump inhibitors.
- Taking medications and prophylactics against ulcers and cancer of the stomach.
Wrong diet
What can the smell of acetone and urine from the mouth say? Another reason is the wrong diet. Perhaps a person consumes a large number of foods that cause the formation of ammonia in the body. And its smell is very similar to the smell of urine.
If a person adheres to a high-protein or ketogenic diet, the problem can accompany him constantly. It is aggravated by eating large quantities of onions and garlic.
Bad habits also have an effect. One of the consequences of a strong addiction to alcoholic beverages is just such a bad breath. This is due to the fact that with the use of alcohol, the production of saliva decreases. Bacteria, which are a source of unpleasant odors, accumulate in the mouth.
How to eliminate with the wrong diet?
The way to solve the problem is simple: balance your diet, refuse to drink alcohol. Over time, halitosis will no longer bother you. Be sure to enrich your diet with fresh fruits and vegetables. If making the right menu is difficult for you, it will not be superfluous to contact a nutritionist with this problem.
Chronic renal disease
CKD (chronic kidney disease) is a combination of disorders and diseases that damage the kidneys and limit their filtration functions. The consequence of this is the accumulation of toxins in the body. One of them is ammonia. It can be the cause of the smell of urine from the mouth in a child and an adult.
This symptom is far from the only one with CKD. The patient may also note the following:
- High blood pressure.
- Anemia.
- Abnormal excess of electrolytes.
- Problems with heart.
- Accumulation of excess fluid in the body.
CKD leads to a number of diseases of the cardiovascular system, renal failure. The risk of stroke also increases.
There are several risk factors that contribute to the development of CKD itself:
- Diabetes.
- Systematically high blood pressure.
- Hereditary predisposition.
- Addiction to drugs.
How to eliminate with CKD?
Unfortunately, it is impossible to cure chronic kidney diseases once and for all today. Therapy is aimed only at alleviating the symptoms of diseases. The patient needs to change his lifestyle, adhere to a special diet. Mandatory medical treatment: taking drugs that lower the level of bad cholesterol in the blood, blood pressure indicators.
In severe forms of CKD, a cardinal measure such as a kidney transplant may be required.
Uremia
Uremia is the last stage of renal failure. Here the kidneys practically do not function, cannot filter the blood. From here, urea, creatine, and nitrogenous products accumulate in the body. They are not excreted in the urine, but remain in the blood. The smell of urine from the mouth in a woman and a man can appear due to the accumulation of these nitrogenous products.
Uremia is a serious condition requiring hospitalization and emergency medical care. Dialysis is urgently needed. In some cases, a kidney transplant is required.
General recommendations
If we read with Dr. Komarovsky about the smell of urine from the mouth of a child and an adult, we learn that it does not always indicate any disease or disorder. Odor can only be one of the alleged symptoms. In most cases, it indicates insufficient or improper oral hygiene.
To get rid of the bad smell, you need to follow these simple recommendations:
- Drink more fluids - both pure drinking water, and juices, decoctions, teas, fruit drinks.
- Cut back on coffee, sodas, red meat, dairy, and refined sugar.
- Enrich your diet with fresh fruits and vegetables, and legumes.
- Avoid excessive drinking.
- Say goodbye to a bad habit like smoking. It is she who, in most cases, is the cause of bad breath.
Independent disease
Bad breath can also be an independent disease. It is called halitosis. Distinguish between its physiological and pathological form.
Most often, the problem torments a person in the morning. And this is not surprising: during the night both bacteria and their metabolic products accumulate in the oral cavity. They are sources of unpleasant odor. Such halitosis is physiological. It is eliminated simply by thorough brushing.
Physiological halitosis is also bad breath caused by the use of certain foods. For example, onions, garlic, sour cabbage. This smell is eliminated independently. With the excretion of the substances that caused it.
But if the bad breath is difficult to eliminate by brushing your teeth, chewing gum, then its cause is pathological.
Pathological Halitosis
The smell of urine from the mouth is one of the forms of pathological halitosis. For all varieties of the disease, a list of universal causes can be distinguished:
- Diseases of the teeth, gums, and oral cavity. The smell here will be a consequence of the vital activity of bacteria, the development of an inflammatory or already purulent process. The main causes are caries, tartar, periodontitis, pulpitis, stomatitis, periodontitis. With these problems, there is persistent bad breath, which can be eliminated only by treatment of the underlying disease.
- Xerostomia (systematic dry mouth). Saliva not only moisturizes the oral cavity. It also has bactericidal qualities. It not only kills bacteria, but also neutralizes the products of their vital activity, rinses and cleanses the oral cavity of the above. If saliva is not sufficiently produced, then the products of bacterial activity accumulate in the mouth. That is why the smell is formed. The reasons for the xerostomia are many. It can be both certain diseases, and medication and the patient's age. Over time, the salivary glands begin to work less intensively, and the composition of saliva itself changes - it loses its bactericidal properties.
- ENT diseases. In particular, sinusitis, chronic tonsillitis, runny nose, tonsillitis.
- Renal, liver failure.
- Gastritis, stomach ulcer.
- Pulmonary disease.
- Smoking. The smell is caused by substances contained in tobacco smoke and certainly settling in the oral cavity. The only way to get rid of the smell here is to simply quit smoking.

Varieties of smell
In addition to the smell of urine from the mouth, a person can overcome other types of unpleasant odors. Not always do they speak accurately about the development of a specific disease. But may be one of its manifestations. Therefore, timely anxiety and a visit to the doctor will never be superfluous.
May be the following:
- Hydrogen sulfide odor (resembles the smell of rotten eggs). It can talk about the decay of protein substances in the body. In particular, this is observed with digestive problems. May indicate gastritis or peptic ulcer.
- Sour smell. The mouth may feel the same aftertaste. May be a symptom of gastritis with high acidity. It usually appears at an early stage of the disease, when other characteristic symptoms are not yet apparent.
- Bitter smell. At the same time, there is a taste of bitterness in the mouth. It can talk about diseases of the gallbladder and liver. Also, with these diseases, a yellow coating on the tongue often appears.
- The smell of acetone. There is also a sweet taste in the mouth. May indicate the development of diabetes.
- The smell of feces. This symptom often indicates problems with the intestinal tract. In particular, it can talk about the development of dysbiosis, intestinal dyskinesia, or tract obstruction.
- Putrid smell. Indicates the presence of diseases of the oral cavity or respiratory tract. Most often, it is felt in inflammatory processes developing in the teeth and gums.

The smell of urine from the mouth is a manifestation that can be of either a physiological or pathological nature. In the first case, it is worth talking about an improper diet, insufficient oral hygiene. In the second, about the development of serious pathologies.
