Diabetic Ketoacidosis caused Casey Johnson's death at age 30

Heiress Casey Johnson, 30, died of natural causes.

According to the  LA County Coroner the cause was Diabetic Ketoacidosis. 

This is the medical term for lack of insulin, which leads to diabetic coma. 

Casey was diabetic and needed insulin shots on a regular basis. She had been hospitalized twice before her death for diabetic comas. 

Casey, who was found dead alone in her home, was reportedly not taking her insulin shots, was not exercising, did not follow her strict diet and was not taking other medicines she needed.

So sad.
