Ketoacidosis
Diabetic ketoacidosis  (DKA) is caused by untreated high blood glucose (hyperrglycemia). If does not get treated, it can develop into a life threatening sickness. The body breaks down fat at a high rate.  It is caused by a lack of insulin and a high number of ketones which causes blood to become acidic. This sickness is an emergency that can lead to coma or death.
