Fasting for long periods of time or the intermittent fasting diet can lead to ketonuria. During fasting, your liver starts to use up fat and protein reserves in your body to keep it going. This causes ketone formation and ketonuria. Diabetes mellitus.

What does ketones in urine mean anorexia?
Ketoacidosis is a metabolic state associated with high levels of ketones in the blood. Ketones build up when the body breaks down fatty acids to use for energy in place of carbohydrate. Starvation ketoacidosis occurs when the body has not received enough glucose as its primary energy source for a prolonged period.
What conditions cause ketonuria?
- Starvation.
- Digestive disturbances.
- Dietary imbalance (high fat/low carbohydrate diet)
- Eclampsia.
- Prolonged vomiting and diarrhea.
- Glycogen storage diseases.
- Severe, sustained exercise.
- Fever.
Can anorexia cause ketoacidosis?
This is known as starvation ketoacidosis. Here, we present the case of a 38-year-old female with anorexia nervosa who was diagnosed with starvation ketoacidosis. Poor dietary intake, prolonged fasting, malnutrition, alcoholism, and protein-based diets may induce ketoacidosis without diabetes mellitus.
Why do ketone bodies increase during starvation?
Circulating ketone body concentrations rise during prolonged starvation. During starvation, most tissues utilise fatty acids and/or ketone bodies to spare glucose for the brain. Glucose utilisation by the brain is decreased during prolonged starvation as the brain utilises ketone bodies as the major fuel.
Is ketosis and ketonuria the same?
Ketonuria is a sign that your body is primarily using fats and protein for fuel. This is called ketosis. It’s a normal process if you’re fasting or on a low-carbohydrate, ketogenic diet. A ketogenic diet does not typically pose a health risk if it’s done in a balanced way.
Can weight loss cause ketones in urine?
Yes, having a certain amount of ketones in your blood, urine or breath means that your body is burning fat. Ketone levels in your blood need to be between 0.5-3 mg/dL for your body to achieve optimal ketosis, which is the ideal state for weight loss.
What causes false positive ketones in urine?
Drugs containing free-sulfhydryl groups such as captopril (an antihypertensive drug) and D-penicillamine (an antibiotic) can produce false-positive ketone results on the reagent strip. Highly pigmented urine can also produce a false-positive result.
What causes high ketones?
Without enough insulin, your body can’t use sugar properly for energy. This prompts the release of hormones that break down fat as fuel, which produces acids known as ketones. Excess ketones build up in the blood and eventually “spill over” into the urine.
What causes ketones in urine if not diabetic?
People without diabetes can also have ketones in the urine if their body is using fat for fuel instead of glucose. This can happen with chronic vomiting, extreme exercise, low-carbohydrate diets (ketogenic or keto diets), or eating disorders.
Which test will be positive in starvation state in urine?
Ketonuria is a medical condition in which ketone bodies are present in the urine. It is seen in conditions in which the body produces excess ketones as an indication that it is using an alternative source of energy. It is seen during starvation or more commonly in type 1 diabetes mellitus.
What does no ketones in urine mean?
Does malnutrition cause ketoacidosis?
Malnutrition and poor dietary intake are ways to enter a state of starvation that may result in ketoacidosis [4]. Gastric banding has also been associated with a risk of starvation ketoacidosis [5].
Is ketosis a starvation mode?
Analysis: When people consume a ketogenic diet, the liver produces ketones from fat as an alternative to using glucose as a circulating source of energy for the body. This state of ketosis mimics what occurs during starvation.
How can you tell the difference between diabetic ketoacidosis and starvation?
Unlike patients with diabetic ketoacidosis, patients with starvation ketosis release insulin when carbohydrate is administered. They are also producing high levels of glucose elevating hormones such as glucagon and have depleted glycogen stores. These hormones cause the lipolysis which helps generate ketones for fuel.
How might starvation affect the results of a urinalysis?
Ketones in the urine (ketonuria) can often be detected by dipstick. Ketones are formed when the body breaks down fat. Ketones can appear in the urine as a result of starvation or uncontrolled diabetes mellitus and occasionally after drinking significant amounts of alcohol.
Can starvation cause protein in urine?
A short duration of starvation can cause the acceleration of protein metabolism3 and increases in nitrogen excretion, leucine flux and oxidation. All of the above observations illustrate that the effect of starvation on the body may possibly reflect urinary protein changes.
What occurs in the body during starvation?
Metabolism slows, the body cannot regulate its temperature, kidney function is impaired and the immune system weakens. When the body uses its reserves to provide basic energy needs, it can no longer supply necessary nutrients to vital organs and tissues. The heart, lungs, ovaries and testes shrink.
Does ketones in urine mean dehydration?
High levels of ketones in urine should always be investigated by a doctor, and treated if needed. This is because an accumulation of ketones in the blood can result in several health problems such as dehydration, electrolytic unbalance, acidosis, and even coma.
Is ketonuria a ketone body?
Ketonuria occurs when high levels of ketone bodies which occur when cells are broken down for energy are present in the urine. Ketonuria can be dangerous if ketones levels become high and may need to be monitored amongst people with diabetes who are prone to high blood glucose levels.
What is difference between ketosis and ketoacidosis?
Ketosis is a metabolic state the body goes into when it doesn’t have enough glycogen from carbohydrates to burn for energy. Ketoacidosis is a complication of diabetes (typically Type 1) that causes the body to produce excess blood acids.
What is starvation ketoacidosis?
Starvation ketoacidosis (SKA) represents one of three metabolic acidoses caused by the accumulation of ketone bodies within the bloodstream. While easily treated, it is a diagnosis that can be easily missed in patients with an unexplained metabolic acidosis.
Can bulimia cause ketones in urine?
Eating disorders: Anorexia nervosa and bulimia nervosa can also cause ketones to appear in the urine. In these individuals, starvation is one of the causes of severe ketoacidosis, even when the patient denies diet restriction.
Can non diabetics get ketoacidosis?
Non-diabetic ketoacidosis is a rare condition which can be caused by starvation. Lack of glucose can force the body into ketogenesis causing a metabolic acidosis. As previously reported in the literature, ketoacidosis might, on rare occasions, be caused by a diet with low carbohydrate content.
When should you test for ketones in urine?
Your doctor will probably tell you to test your ketones when: Your blood sugar is higher than 250 milligrams/deciliter (mg/dl) for two days in a row. You’re sick or you’ve been injured. You want to exercise and your blood sugar level is over 250 mg/dl.
