ketoaciduria
Noun: A medical condition characterized by the presence of excessive amounts of ketone bodies (such as acetoacetate and beta-hydroxybutyrate) in the urine. This condition is typically associated with metabolic states where the body burns fat for fuel instead of glucose, such as in uncontrolled diabetes mellitus or prolonged starvation.
Ketoaciduria is a technical medical term used to describe a specific laboratory finding and clinical sign. It is primarily used in medical diagnosis, reports, and literature. - The patient's lab results confirmed ketoaciduria, prompting immediate intervention for suspected diabetic ketoacidosis. - Ketoaciduria can be an indicator of severe insulin deficiency.
- The presence of alongside hyperglycemia is diagnostic for diabetic ketoacidosis (DKA).
- In cases of extreme fasting, may develop but is usually less severe than in diabetic cases.
- The doctor ordered a urinalysis to check for .
- Pathophysiological Context: is not a disease itself but a symptom of an underlying metabolic derangement. It results from ketosis (elevated ketones in the blood) when the renal threshold for ketone reabsorption is exceeded.
- Diagnostic Significance: While is a hallmark of diabetic ketoacidosis, it must be interpreted in conjunction with blood glucose, pH, and electrolyte levels for an accurate diagnosis.
- Ketonuria: A more general term for the presence of ketones in the urine. often implies a significant, clinically relevant level of ketonuria, particularly with acidotic ketones.
- Ketoacidosis: The broader, more life-threatening clinical syndrome of which is a part. Ketoacidosis involves metabolic acidosis due to excessive ketone production in the blood.
- Acetonuria: An older term sometimes used synonymously with ketonuria, specifically referring to acetone in the urine.
- Ketonuria (though this is a closely related, not always perfectly identical, term)
- Pathological ketonuria
The term specifically denotes an excessive or abnormal quantity. Small amounts of ketones in urine (e.g., after exercise or a very low-carbohydrate diet) may be termed ketonuria but might not be clinically labeled ketoaciduria unless associated with an acidotic state. Its primary association is with diabetes mellitus, especially type 1.
