Excessive formation of ketone bodies (acetone) results in increased blood levels (ketonemia) and increased excretion in the urine (ketonuria). This condition is associated with a decreased availability of carbohydrates, such as dieting or decreased use of carbohydrates. Diabetes and alcohol consumption are common causes of ketoacidosis. Acetone is one ketone body formed from acetoacetate. Ingestion of isopropyl alcohol also leads to the formation of acetone.
