How do you determine cause of death is insulin overdose?

To determine if insulin overdose is the cause of death, a forensic pathologist would conduct a thorough investigation, including a review of the deceased's medical history, circumstances surrounding the death, and potential insulin use. Toxicology tests would measure insulin levels in the blood, looking for concentrations that exceed therapeutic ranges. Additionally, the presence of hypoglycemic symptoms or related complications, such as seizures or coma, would support the diagnosis. The investigation would also consider other possible causes of death to rule out alternative explanations.
