Have you ever noticed a strange smell coming from your urine? Perhaps it smells sweet or fruity or even like nail polish remover. If so, you may be experiencing increased ketones in your urine. Ketones are organic compounds that can be produced by your body when it burns fat for energy instead of glucose. This process is known as ketosis, and it can occur for various reasons, such as fasting, following a low-carb diet, or in people with diabetes.
While some ketones in urine are normal, excessively high levels can cause concern, which may indicate a severe medical condition. In this article, we will explore the causes, symptoms, and potential risks associated with ketones in the urine and what you can do to prevent and manage this condition.
What is Ketones in urine means?
Ketones in the urine indicate a medical condition known as ketosis. Ketosis occurs when the body does not have enough sugar (glucose) for energy and instead starts to break down stored fat for energy. The by-product of this fat breakdown is ketones, which are acidic compounds released into the bloodstream and eventually excreted in the urine.
Ketones in the urine are usually detected with a urine dipstick test and can indicate a range of medical conditions, from diabetes to certain types of kidney disease. It can also be caused by fasting, starvation, overexercising, or excessive alcohol intake.
High levels of ketones in the urine can indicate a medical emergency known as diabetic ketoacidosis, which can be life-threatening if not treated promptly. It is essential to seek medical attention if ketones are detected in the urine, especially if high glucose levels accompany them.
What is a Ketones in Urine Test?
Ketones in the urine are molecules produced by the body during fat metabolism. They can be either acetoacetate or beta-hydroxybutyrate. The normal range is 0-8 mg/dL.
Ketones in the urine are typically measured with a urine test called a ketone test strip. This simple, non-invasive test involves dipping the test strip into a urine sample and waiting for the results to appear. If the ketone level is higher than usual, it may indicate a potential medical problem.
Ketones in the urine can also be tested with a blood test. This test is more accurate than a urine test but is also more invasive. The blood test results can indicate if you have type 1 or type 2 diabetes or insulin resistance.
Ketones in the urine can also be tested with a breath test. This test measures the amount of acetone in your breath. Acetone is produced when the body breaks down fat. If you have a high level of acetone in your breath, it may indicate diabetes.
What Are the Symptoms of Ketonuria?
There are some common symptoms of ketonuria include:
- Sweet-smelling breath: People with ketonuria may have a sweet, fruity, or acetone-like odor on their breath.
- Increased urination: People with ketonuria may urinate more frequently than usual as their body tries to rid itself of excess ketone bodies.
- Thirst: People with ketonuria may experience increased thirst and drink more than usual.
- Fatigue: Excess ketones can interfere with normal energy production, leading to fatigue and tiredness.
- Nausea and vomiting: People with ketonuria may experience nausea and vomiting due to the presence of ketones in the stomach.
- Abdominal pain: Ketonuria can cause abdominal pain due to the presence of ketones in the digestive tract.
- Weakness and confusion: Ketones can interfere with normal brain function, leading to confusion, weakness, and sometimes even loss of consciousness.
- Rapid breathing: Rapid, deep breathing is a symptom of ketonuria and can be a sign of excess ketone production.
- Weight loss: People with ketonuria may experience rapid weight loss due to the body using fat for energy instead of glucose.
- Dark urine: Dark, concentrated urine is a common symptom of ketonuria, as ketones are excreted in the urine.
14 Common Cause Ketones in Urine
1. Poorly Controlled Diabetes
Diabetes is a severe metabolic disorder that occurs when the body cannot produce enough insulin or properly use the insulin it produces. When poorly controlled, diabetes can cause an accumulation of ketones in the urine.
Ketones are acids formed when the body breaks down fat for energy instead of glucose. This can occur when glucose levels are consistently high, as the body will rely on fat for energy instead. (Source)
High levels of ketones in the urine can lead to ketoacidosis, a severe medical condition characterized by nausea, vomiting, abdominal pain, confusion, and fruity-smelling breath. This can be life-threatening if left untreated.
To avoid the accumulation of ketones, it is essential to maintain proper control of diabetes. This includes regularly monitoring blood glucose levels and taking the appropriate medications or insulin. Furthermore, following a healthy diet and exercise routine is essential to help keep glucose levels in check.
2. Underlying infection or illness
Diabetes is one of the most common underlying causes of ketonuria. When the body cannot produce enough insulin to break down glucose, it begins to break down fat instead, producing ketones.
Infections can also lead to ketonuria. Common infections that cause ketonuria include urinary tract infections, pneumonia, and meningitis.
Metabolic disorders like Addison’s disease and Cushing’s syndrome can also cause ketonuria. In Addison’s disease, the adrenal glands do not produce enough hormones, causing the body to break down fat and protein for energy.
Cushing’s syndrome is a disorder caused by an overactive pituitary gland, which can produce excessive cortisol and cause ketonuria.
3. Ketogenic Diet
Ketogenic diets are high-fat, moderate-protein, and low-carbohydrate diets that can help to reduce weight, promote heart health, and manage certain health conditions.
When following a ketogenic diet, the body enters a state of ketosis where fatty acids are broken down to produce ketones which can be used as the body’s primary energy source. This process causes ketones to be excreted in the urine.
Testing for ketones in the urine is a way to determine if a person is in ketosis and is following the diet correctly. People on a ketogenic diet must monitor their ketone levels to ensure they are in the desired range.
If the levels are too high, it could mean that the person is overeating fat or not eating enough carbohydrates. If the levels are too low, it could mean that not enough fat is being ingested.
4. Long-term Vomiting or Diarrhea
Long-term vomiting and diarrhea can cause ketones in the urine. This is because when the body cannot absorb enough nutrients from food, it will break down fat for energy instead.
As a result, ketones are produced and excreted in the urine. People who suffer from chronic vomiting or diarrhea may experience dehydration, electrolyte imbalances, and increased ketone levels.
It is essential to seek medical attention immediately if you experience long-term vomiting or diarrhea, as it can lead to severe medical conditions, such as ketoacidosis.
Treatment may include replacing lost fluids with oral or intravenous fluids and electrolyte replacement. If the underlying cause of the vomiting or diarrhea is not treated, the ketone levels may remain elevated.
5. Diabetic Ketoacidosis
Diabetic Ketoacidosis (DKA) is an acute complication of diabetes caused by a severe shortage of insulin. It occurs when the body breaks down fat for energy instead of glucose, producing acidic ketones. These ketones then spill over into the urine, causing ketones to be present.
The most common symptoms of DKA are frequent urination, increased thirst, fatigue, nausea, and vomiting. If left untreated, DKA can be life-threatening.
The leading cause of DKA is an inadequate supply of insulin, which may be due to an illness, skipping insulin doses, or being unable to access insulin.
Other risk factors include a lack of physical activity, dehydration, and stress. Treatment for DKA involves restoring normal body fluid levels, replacing electrolytes, and administering insulin to reduce ketone levels. If detected and treated early, DKA can be reversed and managed effectively.
6. Starvation
Starvation can cause ketones to appear in the urine. These ketones are produced when the body breaks down fatty acids for energy. When a person is not consuming enough food, the body will draw on its fat stores as an energy source. (Source)
This causes the breakdown of fatty acids, resulting in the production of ketones. Ketones in the urine indicate that the body is not getting enough food and is forced to break down fat for energy.
If left untreated, starvation can cause long-term health problems and even death. To avoid ketones in the urine due to starvation, it is essential to ensure that a healthy and balanced diet is being consumed.
This can include a variety of foods from all food groups, including proteins, carbohydrates, and fats. Eating regularly throughout the day can also help ensure the body does not deplete its energy stores.
7. Excessive Exercise
Excessive exercise can cause the body to produce ketones, leading to ketones in the urine. Ketones are by-products of fat breakdown and are used by the body as an energy source. When the body produces too many ketones, it can lead to ketoacidosis. This is a health emergency and can be life-threatening.
The best way to avoid excessive ketone production is to avoid over-exercising. Listening to your body and taking regular breaks during exercise are essential. Stay hydrated and drink plenty of fluids to replace lost electrolytes.
8. Alcohol Use Disorder
Alcohol Use Disorder (AUD) is a severe medical condition that can cause ketones to appear in the urine. AUD is caused by excessive and chronic alcohol consumption. When the body breaks down alcohol, it produces ketones, which can be detected in urine.
AUD affects how the body metabolizes alcohol, leading to an excessive build-up of ketones in the blood. This, in turn, causes ketones to be excreted in the urine. Ketones are a type of acid, and their presence in the urine can indicate that the body is breaking down fat instead of using carbohydrates for energy.
People with AUD may also experience dehydration, leading to ketones appearing in the urine. Dehydration causes the body to break down fat for energy, resulting in the production of ketones.
9. Stress
Stress can cause an increase in ketones in the urine. This occurs when the body breaks down fat for energy, which it does in response to stress.
When the body breaks down fat, it produces ketones, which can be detected in the urine. Stress can also cause an increase in cortisol, which increases the body’s metabolic rate, leading to an increase in ketones.
High levels of stress can also lead to dehydration, which can also increase ketone levels in the urine. In addition, stressed people may also have poor eating habits and consume too many carbohydrates, which can lead to an increase in ketones in the urine.
10. Eating Disorders
Eating disorders are severe mental health conditions that can lead to the production of ketones in your urine. It can cause starvation. This will lead to extreme caloric restriction and forces the body to break down fat for energy. In addition, this can induce ketosis and, subsequently, the presence of ketones in your urine.

11. Pregnancy
Pregnant women often have elevated levels of ketones in their urine, as the body is forced to break down existing fat stores for energy.
This is especially true during the third trimester when the baby proliferates. High levels of ketones in the urine may indicate gestational diabetes or other metabolic conditions and should be monitored closely by a healthcare provider.
12. Severe Infections
Severe infections, such as pneumonia, can cause the body’s metabolism to shift, resulting in elevated levels of ketones in the urine.
This is because the body is forced to break down fat cells to generate energy, and the ketones are a byproduct. It is essential to seek medical attention if you have a severe infection and are experiencing increased levels of ketones in the urine.
13. COVID-19
People infected with COVID-19 may experience increased levels of ketones in their urine as the body is forced to break down fat stores for energy.
In some cases, this can be severe, resulting in ketoacidosis, a dangerous condition where the body cannot effectively process the ketones in the urine.
14. Certain medications
Certain medications, such as diuretics, can cause elevated levels of ketones in the urine. Ketones are compounds produced when fatty acids are broken down for energy. When a person takes diuretics, they increase their urine output, and the body breaks down more fatty acids, thus increasing the number of ketones in the urine.
These medications include corticosteroids, which are used to treat various medical conditions, as well as certain antibiotics and chemotherapy drugs. In some cases, the medicines may cause the body to produce more ketones than it can use, resulting in elevated levels in the urine. (Source)
Home Remedies for Ketones in Urine
1. Increase Water Intake: Increasing water intake helps flush out excess ketones in urine and helps maintain the right balance of electrolytes in the body. This can be done by drinking at least eight 8-ounce glasses of water daily.
2. Eat Low-Carb Foods: Eating low-carbohydrate foods, such as vegetables, lean protein, and whole grains, helps reduce the number of ketones in the urine. Eating a balanced diet with plenty of fruits and vegetables can also help keep the body balanced.
3. Regularly: Exercise helps burn off excess ketones in the body, which helps lower the number of ketones in the urine. Regular exercise also helps keep the body functioning correctly.
4. Manage Stress: Stress can cause the body to produce more ketones, raising their levels in the urine. Taking steps to reduce stress, such as yoga, meditation, and deep breathing, can help reduce the number of ketones in the urine.
5. Monitor Carbohydrate Intake: Eating a diet low in carbohydrates may help reduce ketone levels in the urine, as carbs are the body’s primary energy source.
6. Eat More Protein: Eating more protein, such as lean meats, eggs, and beans, may help your body to utilize energy more efficiently, thus reducing the production of ketones.
7. Take Supplements: Taking certain supplements, such as omega-3 fatty acids, chromium, and magnesium, may help to reduce ketone levels in the urine.
8. Get Enough Sleep: Getting enough restful sleep is essential for the body to function correctly and may help to reduce ketone levels in the urine.
Complications of ketoacidosis
1. Acute Kidney Failure
Acute kidney failure is a severe complication of ketoacidosis and occurs when the kidneys cannot filter the acidity out of the bloodstream. This can lead to electrolyte imbalances, a buildup of toxins in the bloodstream, and a decrease in urine production. Symptoms of acute kidney failure include nausea, vomiting, fatigue, confusion, and fluid retention.
2. Pulmonary Edema
Pulmonary edema is a potentially life-threatening complication of ketoacidosis and occurs when fluid builds up in the lungs. This can be caused by a buildup of acids in the bloodstream, leading to decreased oxygen levels. Symptoms of pulmonary edema include shortness of breath, chest pain, coughing up blood, rapid breathing, and rapid heart rate.
3. Cerebral Edema
Cerebral edema is a serious complication of ketoacidosis and occurs when fluid accumulates in the brain. This can cause swelling of the brain and disrupt normal brain function. Symptoms of cerebral edema include headaches, confusion, drowsiness, nausea, vomiting, and seizures.
4. Cardiac Arrest
Cardiac arrest is a medical emergency and is a severe complication of ketoacidosis. It occurs when the heart stops beating, resulting in a lack of oxygen to the brain and other vital organs. Symptoms of cardiac arrest include loss of consciousness, lack of breathing, and no pulse. Immediate medical attention is required to revive the individual.
When should you see a doctor for Ketonuria?
If you are experiencing frequent urination, extreme thirst, nausea, vomiting, weakness, or confusion, seeing a doctor as soon as possible is essential.
Additionally, if you have diabetes, monitoring your ketone levels regularly and seeking medical attention if they become elevated is crucial. Untreated ketonuria can lead to a dangerous condition called ketoacidosis, which can be life-threatening.
Therefore, if you suspect you may have ketonuria, it’s always best to see a doctor to determine the underlying cause and receive appropriate treatment.
