Symptoms of ketones in urine.


A small amount of ketones in the body is normal, but high ketone levels can indicate serious illness or death.

Your body typically burns sugar for energy, but there are times, particularly during prolonged fasting and uncontrolled diabetes, when the body may need to rely on other sources of energy, such as fat. When the body does not have enough sugar or cannot break it down, it turns into fat, which produces substances called ketones.

These ketones are important because the brain can only use glucose and ketones for energy. However, when ketones are too high, they can become toxic to the body and can instead enter the blood and urine.

High levels of ketones in urine range between 1.6 and 3.0 mmol / L, and very high levels exceed 3.0 mmol / L.

Frequent symptoms

There are several reasons why ketone levels in the urine can be high, but people with diabetes are more likely to develop ketonuria symptoms because they either don't produce enough insulin or their bodies don't respond well to insulin.

People with diabetes are unable to use blood sugar for energy, so they may need to test their urine for ketones more often in order to monitor their condition and avoid developing symptoms altogether.

Symptoms of ketonuria or ketones in urine only occur when ketone levels are high, especially above 0.6 mmol / L.

Symptoms of ketonuria include:

  • Frequent urination
  • Increased thirst
  • Muscle pain
  • Fatigue
  • Unexpected weight loss
  • Shortness of breath or trouble breathing
  • Nausea, vomiting, or abdominal pain
  • Confusion
  • Fruity-scented breath

If you have any of these symptoms and suspect that you have diabetes or another condition that is affecting your metabolic profile, your healthcare professional may suggest that you test your ketones immediately.

The following conditions increase the risk of ketonuria:

  • Poorly controlled diabetes or blood sugar levels above 300 mg / dL
  • A history of alcohol abuse.
  • The pregnancy
  • Infection
  • Prolonged fasting
  • Taking ethanol

Rare symptoms

There are three ketone bodies: acetoacetic acid, beta-hydroxybutyric acid, and acetone, which are generally negligible in people's blood and urine after meals or fasting overnight.

These ketones are important reserve sources of energy, but if your diabetes is not well controlled or if you are on a prolonged fast or restrictive diet, these trough amounts can skyrocket to 10-40 mmol / L, 70 times the normal amount. ketones, which must be in the blood or urine.

High levels of ketones are toxic to the body because they acidify the blood, which must have a tightly regulated pH to maintain proper organ function. This is especially important for people with diabetes who are at risk of developing diabetic ketoacidosis, a life-threatening condition.

Other rare ketoacidosis symptoms associated with ketonuria include:

  • Brain edema
  • Heart failure
  • Renal insufficiency
  • Eat
  • Death


Even if you don't have diabetes, you can develop symptomatic ketonuria. This can happen with:

  • Chronic vomiting
  • Extreme exercise
  • Extremely low carb diets
  • Eating disorders
  • Alcohol use disorder
  • The pregnancy

Alcoholics, extreme exercise, and dieters and pregnant women are at high risk of developing symptomatic ketonuria.

When to see a healthcare professional

If you have diabetes and the first signs of ketonuria appear, such as fatigue or increased thirst, you may need to see your doctor. Your doctor may order a urinalysis to check for ketones.

In the meantime, you need to increase your water intake and monitor your blood sugar to make sure your blood sugar is under control.

Whether you're diabetic, have bad breath, feel confused or disoriented, or have trouble breathing, you may have high levels of ketones in your blood that put you at risk. To prevent life-threatening complications, seek immediate medical attention.

Get the word of drug information

If you have diabetes, you are at a higher risk of developing high levels of ketones in your urine. If you have high blood sugar levels and type 1 or 2 diabetes, it is important to monitor your ketone levels to avoid serious health complications.

Even if you don't have diabetes, you can develop symptomatic ketonuria. This can occur with chronic vomiting, extreme exercise, low-carb diets, or eating disorders, highlighting the importance of a healthy lifestyle and a holistic approach to treating and managing ketonuria symptoms.
