What does acetonemia mean?
Acetonemia is the medical term for the presence of acetone in the blood, usually in a concentration high enough to reflect increased ketone production. It is most often associated with ketosis, including the state that can occur during prolonged fasting, severe carbohydrate restriction, or uncontrolled diabetes. The condition is important because substantial acetonemia can signal the metabolic disturbance preceding or accompanying diabetic ketoacidosis, although acetonemia itself is not synonymous with ketoacidosis. Clinicians may discuss the finding in relation to blood testing, insulin deficiency, and the management of diabetes. Outside medical literature, the word is uncommon, but its familiar association with acetone helps explain the characteristic fruity or solvent-like odor that can occur during significant ketosis. Overall, acetonemia names a measurable biochemical finding rather than a disease in itself: the presence of a ketone body that can help clinicians assess the body’s use of fat for energy and the severity of altered glucose metabolism.
nounThe presence or abnormal accumulation of acetone in the blood. It may occur during fasting or in disorders of glucose metabolism and, in severe cases, accompany diabetic ketoacidosis.
- The presence or abnormal accumulation of acetone in the blood, commonly as a sign of increased ketone production or impaired glucose metabolism.
"Blood tests revealed significant acetonemia, prompting the clinician to assess for ketoacidosis."
"Blood tests revealed significant acetonemia, prompting the clinician to assess for ketoacidosis."
"The child was admitted with vomiting, dehydration, and marked acetonemia associated with newly diagnosed diabetes."
The plural is grammatically possible but uncommon because acetonemia is usually discussed as a condition or laboratory finding.
"The chart documented recurrent acetonemias following missed insulin doses."
A fruity or solvent-like breath can be a warning sign of significant acetonemia, particularly when diabetes is not well controlled.

Where does acetonemia come from?
The word was formed in medical Latin from aceto-, a combining form associated with Latin acetum, meaning vinegar, and -emia, a suffix derived from Greek haima, meaning blood. The prefix also appears in terms such as acetone, acetic, and acetyl, all of which ultimately relate to the same Latin word for vinegar. The resulting term literally identifies the presence of acetone in the bloodstream.
How acetonemia is actually used
A technical, chiefly clinical term that is uncommon in general usage. It denotes a biochemical finding rather than a disease in itself and is more specific than a general reference to ketosis.
Easily confused with acetonemia
Acetone is a ketone compound, whereas acetonemia is the presence or accumulation of that compound in the blood.
