Top 6 causes of the smell of acetone from the mouth in adults

The smell of acetone from the mouth - a phenomenon that can make a person reasonably worried about their own health.

This fragrance is known to many, but normally it should not come from a person. And since it arises from the inside, neither brushing your teeth, nor mints or chewing gum helps to get rid of it. And in this case it is necessary to think seriously about the causes of such an anomaly.

The smell of acetone from the mouth may indicate the presence of certain diseases, or it may accompany some physiological processes in the body. Whatever it was, and the record to the doctor when such an aroma appears - the first thing that a person should do.

What is acetone, how is it formed in the body?

Acetone is a chemical that is found in many solvents. It has a rather sharp, unpleasant, unnatural smell. From the mouth, there is usually a smell not only of the chemical acetone itself, but of the "aroma" of pickled apples.

The liver is responsible for the process of lipid breakdown. It is during this time that acetone is formed, which then enters the systemic circulation. Ketone bodies (the medical name for acetone) is a "waste material" from which the body successfully disposes on its own. This happens in healthy people.

Acetone is usually excreted in sweat, urine, and also with exhaled carbon dioxide. If the process of cleansing the body of ketone bodies fails, they gradually begin to accumulate, which leads to an increase in the smell of acetone emanating from the oral cavity.

What does the smell of acetone from the mouth mean?

The smell of acetone from the mouth is an alarming, sometimes even frightening. It is noteworthy that it comes from the lungs, so no measures aimed at weakening it will not give results. Such a deviation can be a serious sign indicating the presence of diseases or pathological disorders in the body. Although sometimes the acetone smell from the mouth may appear for other reasons.

So, what could be the cause of the smell of acetone from the mouth? Let us consider the top 6 main reasons.


Sitting on rigid diets, torturing the body with hunger - these are the measures that many modern people go to in order to get rid of excess weight. Moreover, this concerns not only women, but also men. It is unreasonable dieting or the abuse of therapeutic fasting without a doctor's prescription is one of the frequent reasons why an acetone smell from the oral cavity can appear in an adult.

With this approach to losing weight, patients themselves over time notice negative changes that affect both appearance and health. This is especially true of people who stick to a diet with the complete exception of carbohydrate foods. This leads to a lack of energy and active splitting of fat cells. As a result, the level of harmful substances in the body increases. As a result, the normal functioning of all organs and systems is disrupted.

Excessive enthusiasm for rigid diets that exclude carbohydrates, provokes bouts of weakness, dizziness, irritability, nausea. A person notes the cross section of hair, dry skin, brittle nails. In this case, the appearance of the smell of acetone from the mouth is directly related to the observance of such a diet. That is why before starting a diet course you must visit a doctor and undergo a thorough examination.

The most dangerous ways to lose weight are:

  1. Kremlin diet. It implies a strict restriction of carbohydrates with a preference for protein foods. The diet does not have a balanced diet, so it is very dangerous for the body.
  2. Atkins diet. It is rather a shock mode with very tough limitations, moreover, it is designed for a long period of time. Due to the fact that the body does not receive energy, it begins to “eat up” fat reserves, as a result of which the level of ketone bodies in the blood increases dramatically.
  3. Diet Kim Protasov. This course is designed for 5 weeks, the diet is based on the use of fiber and protein foods. Fats and carbohydrates are minimized.
  4. Protein diet. Based on the use of food enriched with protein, which is extremely dangerous for health. Monotonous diet significantly “hits” the body, which leads to serious violations in its activities.
  5. French diet. This food system is based on the use of meat, vegetables, fruits, fish, greens. At the same time, bread, sweets and fruit juices have to be abandoned. Daily portions of food are small, and the duration of the course is 2 weeks. During this time, the body has time to seriously deplete.


Diabetes mellitus is accompanied by a number of pathological disorders:

  1. In type 1 diabetes, insulin ceases to be produced by the cells of the pancreas in the required amount, so the body cannot normally absorb glucose.
  2. For the second type of diabetes is characterized by the absence of violations of the production of insulin, but the body still can not fully absorb glucose.

In both cases, glucose is not absorbed, but first accumulates in the blood, and then excreted from the body with urine, during urination. As a result of this process, the body remains without a full-fledged energy supply, and suffers from hypoxia and "energy hunger." To fill this deficiency, the body begins to actively break down fats and proteins.

As a consequence, there is an increased secretion of acetone, and its organic component, the ketone, gradually accumulates in the blood. Under this influence, the body is slowly being poisoned from within. A person feels weakness, dizziness, lethargy, and the smell of acetone begins to emanate from his mouth. Moreover, the patients themselves notice that the urine also acquired such a smell, and the surrounding people can sense it when they come in contact with a diabetic, since the "aroma" of acetone also comes from the skin of the patient.

Diabetes mellitus is a dangerous disease, the fight against which should be started immediately after its detection. To do this, refer to an endocrinologist, and pass a blood test for sugar and ketones.

Thyroid disease

In cases of thyroid gland diseases, accompanied mainly by thyrotoxicosis, the patients also have an acetone mouth odor. So, with thyrotoxicosis, the thyroid gland begins to intensively produce the hormones thyroxine and triiodothyronine. Under their influence, there is an active breakdown of fats and proteins. This is what leads to an increase in the concentration of ketone bodies and the smell of acetone from the mouth.

For endocrine disorders, patients complain of:

  • hyperhidrosis;
  • increased nervousness, irritability, irritability;
  • tachycardia.

Also when thyrotoxicosis is bug-eyed, and in the advanced stage it leads to intense and abrupt weight loss. The normal process of digestion is disturbed, colic appears. For treatment, drugs based on hormones that suppress the production of thyroxin are used. Both tablets and infusion solutions can be used.

Liver and kidney disease

Liver and kidneys can rightly be called filters of the human body. They literally absorb harmful substances, filter them, "sending" only purified, useful substances into the systemic circulation. If the patient has chronic diseases of these organs (pyelonephritis, nephritis, renal or hepatic insufficiency, hepatitis, cirrhosis, etc.), then this well-established system undergoes negative changes. Toxins and other harmful substances, including acetone, begin to accumulate in the body.

In severe cases of these diseases, the smell of acetone can come not only from the oral cavity or from urine. Even the skin of the patient will have an unpleasant odor. A symptom can be completely eliminated only after undergoing a full course of therapy. In the chronic course of pathologies of the liver or kidneys, the elimination of unpleasant acetone breath from the mouth is temporary, and lasts until the disease aggravates again.

Infectious diseases

Infectious pathologies of various etiologies and localization significantly weaken the human body. But the abnormally high concentration of ketone bodies in the blood in this situation is not a very common phenomenon. Usually such a deviation is observed in the case when the disease is severe.

But there are situations when infectious diseases can cause an increase in the level of ketone bodies in the blood. Thus, such a violation occurs in pregnant patients, as well as in patients in whom such pathologies occur in a chronic form.

In many patients, marked ketonemia is observed after surgery, as well as dehydration.

Pancreatic Diseases

Increased formation of ketone bodies also occurs during pancreatitis. Against the background of chronic diseases of the pancreas, pathological halitosis is also a frequent phenomenon. It is possible to get rid of unpleasant acetone smell only after treatment. The use of sprays to freshen breath, as well as the use of peppermints or chewing gums will be ineffective.

The smell of acetone in children is a special case.

The appearance of the smell of acetone from the mouth in children is considered to be common, occurring in every 5 children. If such outbreaks are periodic, then we are talking about acetonemic syndrome, which can be a consequence of:

  • infectious pathologies;
  • overeating;
  • improper, unbalanced nutrition;
  • stress;
  • overwork;
  • violations of the internal organs;
  • endocrine disorders;
  • CNS diseases.

Sometimes acetonemic syndrome in children is the result of a genetic predisposition.

What can be done with such a problem?

Only one way out of the situation is to identify the cause of the smell of acetone from the oral cavity, and its elimination. If this disease, then it must be cured, if stress - to eliminate its effects and try to avoid it in the future.

In addition, it is important:

  • carefully monitor the functioning of the liver, kidneys, endocrine system in general and the thyroid gland in particular;
  • abandon thoughts of self-medication;
  • follow a diet for weight loss only after consulting a nutritionist;
  • monitor sugar levels and maintain normal insulin concentrations (advice for diabetics).

If these measures do not help, then the patient will have to radically change their lifestyle.

How to determine acetone in urine?

If there is a smell of acetone from the mouth, it can be detected in the urine. This can be done at home - with the help of special rapid tests, which are sold in pharmacies. They work on the principle of a pregnancy test.

The strip must be removed from the protective packaging, and immersed in a container with urine. If not a special container is used for analyzing the urine, but a glass or jar, then it should be sterilized beforehand or rinsed with soda solution.

The collection of biomaterial must also be taken responsibly. There should be no foam on the surface of the urine. If these simple conditions are met, then a test for acetone in the urine will give reliable results. During the procedure, you need to pay attention to the fact that the more saturated the color of the test strip, the higher will be the indicators of acetone in the urine.
