Breath odor of diabetic ketoacidosis

Diabetic ketoacidosis

is a severe acute complication of diabetes. When insulin is severely deficient or deficient, the body cannot effectively use glucose to produce energy and breaks down fat to provide energy. During fat decomposition, a large number of ketone bodies are produced, including acetoacetic acid, β-hydroxybutyric acid and acetone. As ketone bodies accumulate, they are excreted through breathing. Acetone has a distinctive odor, similar to that of rotten apples, which leads to this characteristic odor on the patient's breath.
