Death from severe hypothermia can produce complex findings during a forensic examination. In some cases, blood analysis may show increased concentrations of acetone and isopropanol, even when there is no evidence of diabetes.

One possible explanation is the body’s response to prolonged cold exposure. As the body runs out of available glucose, it may break down fat for energy. This process can increase the production of ketone bodies, including acetoacetate and acetone. Under certain conditions, acetone may also be converted into isopropanol.

These findings may support a history of severe cold exposure, but they are not specific proof of hypothermia. Similar chemical patterns can occur with fasting, starvation, alcohol-related ketoacidosis, diabetes, decomposition, or some laboratory and storage conditions. For that reason, forensic specialists must interpret toxicology results together with the circumstances of death, autopsy findings, medical history, and additional laboratory tests.

The absence of diabetes is important, but it does not by itself establish hypothermia as the cause of death. A reliable conclusion requires a complete forensic investigation and the exclusion of alternative explanations.
