What Is Ketonuria?
Ketones in the urine are generally seen in uncontrolled diabetes mellitus, fasting, dieting, starvation, and eating disorders. It can also occur during pregnancy. Diabetics prone to ketonuria require regular monitoring of their urine for signs of ketone buildup that can cause various life-threatening symptoms unless treated promptly. Other names for ketonuria are ketoaciduria and acetonuria. Ketones are formed in the liver as a byproduct of fats and proteins. These ketone bodies are used as a source of energy when enough glucose is not present. In cases such as diabetes mellitus, fasting, and other health conditions, the body produces a large amount of urine in the kidneys. The increased level of ketones is then excreted in the urine, called ketonuria. If the ketone bodies are not excreted in urine, it builds up. This increase in acid buildup is called ketoacidosis and is harmful to the body.
What Is Ketone?
Your liver produces ketone bodies, which are acidic molecules. Ketones are by-products the liver produces while breaking down fats to provide energy. When your body does not have enough glucose, it turns to ketones for energy. The main energy source for the body is glucose, which is derived from carbs. Urine ketone levels indicate that your body uses fat instead of glucose to produce energy. Ketones are typically excreted as waste in extremely small concentrations in urine.
Your body produces more ketones than it can utilize while you are fasting or when you have medical problems like diabetes. As a result, your liver produces more ketone bodies. When you urinate, your body attempts to eliminate them, which leads to elevated amounts of ketones in the urine, a condition also referred to as ketoaciduria, acetonuria, or ketonuria. Elevated amounts of ketones in the body exacerbate acid accumulation in the blood.
What Causes Ketonuria?
- Fasting: An intermittent fasting diet or fasting for long periods can cause ketonuria. During fasting, the liver breaks down fat and protein without glucose to produce energy, forming ketone and ketonuria.
- Keto Diet: A ketogenic diet involves limiting or cutting out carbohydrates and eating fats and protein for energy. This low-calorie diet makes the body use protein and fats as fuel to break down and produce energy. This causes ketone formation and excretion. Diabetes mellitus is a condition in which the body has low insulin levels. The cells cannot store or use glucose for energy because low insulin results in high blood sugar. The body then uses fats and proteins to break down and produce energy, forming ketone bodies. These ketone bodies, if not excreted in urine, can build up in the blood, causing diabetic ketoacidosis.
- Renal Glycosuria: This abnormal condition occurs due to improper functioning of the renal tubules, releasing glucose through urine. Low blood sugar levels characterize it. This condition causes the liver to burn fats and proteins to produce energy, resulting in ketonuria.
- Glycogen Storage Disease: In this disease, the liver is forced to use fats and proteins instead of glycogen as a source of energy. This leads to the formation of ketone bodies and ketonuria.
- Excessive Alcohol Consumption: Excessive intake of alcohol is associated with a lack of sufficient nutrient absorption and a state of chronic starvation. Moreover, the metabolism of ethanol inhibits gluconeogenesis. This causes the production of ketones.
Other causes include the following:
- Heavy strenuous exercise.
- Long-term or intermittent fasting.
- Pregnancy.
- Starvation.
- Hormones such as epinephrine and cortisol.
- Stress and illness.
What Are the Symptoms of Ketonuria?
- Frequent urination.
- Heavy breathing.
- High blood sugar levels.
- Vomiting.
- Fruity-smelling breath.
- Confusion and tiredness.
- Dehydration and thirst.
- Anorexia (eating disorder).
- Breastfeeding.
How Is Ketonuria Diagnosed?
Ketonuria is diagnosed by blood and urine tests.
- Urinalysis: Before the test, the patient should only consume something briefly, collect the urine specimen in a sterile container, and provide it to a doctor for testing. The laboratory technician can provide the patient with a urine collection container and a test strip for at-home testing. The test strip and the container have a color chart indicating the ketone level. The patient must only consume something for a few hours before the test. In both circumstances, the ketones in the urine tests will specify whether the levels are minor, moderate, or high. Different factors such as age, gender, medical history, existing medication, diet, and activity level can impact ketone levels.
- Blood Analysis: Ketone bodies appear in the urine and the blood, so a blood glucose test can be done, too. The test is often conducted in a laboratory. However, patients taking insulin can get this test by a prescription from their doctor for blood glucose test for at-home testing. It is done as follows:
- Follow the instructions on the packaging to place the needle accurately into the lancet pen.
- Place the test lancet against the finger.
- To saturate the strip, press the button and wait until the blood saturates.
- Leave it there until the meter records.
- Wait for some time and record the results.
- Always use an unopened, sterile, non-expired test strip and blood glucose meter for accurate, safe testing.
Recording the Results-
The results from a urine test for ketones will either be negative or more than normal. A negative test result indicates the ketone levels are normal for the individual. A higher-than-normal result means the test detected ketones in the urine. The result can be read as follows:
- Less Than 20 mg/dL (milligrams per deciliter): Mild levels of ketones.
- Between 30 and 40 mg/dL: Moderate levels of ketones.
- Above 80 mg/dL: Large levels of ketones.
For the blood test, the test results can be classified into three ranges:
- 0.6 mmol/L (millimoles per liter) or Below: It is in the normal range.
- 0.6 to 1.5 mmol/L: There are ketones in the blood. Consult a doctor about possible options.
- 1.6 mmol/L or Above: This indicates a high risk of acquiring diabetic ketoacidosis. Consultation with a doctor is needed immediately.
A blood test can be more accurate as urinalysis only inspects for current or recent ketone levels. A high result could be due to other factors as follows:
- High fever or recent illness.
- High protein diet or low carbohydrate diet.
- Eating disorders such as anorexia.
- Excessive alcohol consumption.
- Overproduction of the thyroid hormone.
- Patients still determining their results should contact a specialist to analyze them, mostly for at-home testing.
How Is Ketonuria Treated?
Treatment for ketonuria is comparable to that for diabetic ketoacidosis in more severe cases. You could need to receive life-saving care for:
- Sodium.
- Potassium.
- Chloride electrolytes.
- Fast-acting insulin IV fluids.
The following treatments are used for excessive alcohol consumption-related ketonuria:
- Giving intravenous fluids.
- Monitoring and restocking electrolytes.
- If required, take thiamine glucose.
- Medication to avoid the disastrous effects of alcohol withdrawal.
- Medications to prevent vomiting and nausea.
Patients with starvation-induced ketonuria respond similarly to treatment for alcohol use disorders. Doctors may treat starving patients differently, though, because fasting increases the risk of refeeding syndrome, a severe combination of symptoms brought on by low electrolyte levels that can occur when the body attempts to reprocess meals.
What Are the Complications of Ketonuria?
Ketonuria can cause major health issues in certain situations. It may cause a coma or perhaps death.
- Ketoacidosis: A diabetic coma or possibly death may result from diabetic ketoacidosis, which is a medical emergency. The increase in blood acidity is caused by the spike in ketones in your blood. Elevated acidic states cause harm to internal organs, muscles, and nerves and disrupt physiological processes. Although it can affect anyone with diabetes, type 1 diabetics are more likely to experience this illness.
- Dehydration: Dehydration can result from high blood sugar levels, which raise ketone levels and greatly increase the need to urinate. In addition to dehydration, illnesses that cause ketonuria can result in nausea, vomiting, and diarrhea.
- Pregnancy Complication: Insulin resistance increases throughout pregnancy, especially in the second and third trimesters. This resistance is brought on by the hormonal changes that occur during pregnancy. Ketones in urine may appear earlier and at lower blood glucose levels in individuals with gestational diabetes than in non-pregnant individuals if you currently have diabetes or have this condition identified. Elevated levels of ketones in urine can also result from frequent vomiting during pregnancy or from consuming less fluids, particularly in the latter trimester.
How to Prevent Ketonuria?
It Is crucial to keep your blood sugar under control if you have diabetes. Keep a close eye on your blood glucose levels and be aware of any signs to avoid ketonuria and the difficulties that may arise from it. Consume whole grains, berries, nuts and seeds, green, non-starchy veggies, and healthy fats to help control your blood sugar levels. To balance your carb intake, eat an equivalent amount of proteins, such as those found in meat, fish, eggs, cheese, and tofu. This is because proteins keep blood sugar levels within a normal range by slowing down glucose uptake into the blood.
Conclusion
Ketonuria is caused by fasting or diet, diabetes mellitus, keto diet, and starvation. It is a serious problem when it occurs due to an underlying condition. Ketonuria in diabetes is treated using insulin injections or intravenous (IV) drips. When caused by other illnesses, ketonuria can be treated with medication, an appropriate diet, and therapy. Diabetes needs good control over blood sugar levels. Closely monitoring blood glucose levels and checking for symptoms is necessary to prevent ketonuria and complications that can arise.
