By Mayo Clinic staffDiabetic ketoacidosis is a serious complication of diabetes.
Diabetic ketoacidosis develops when you have too little insulin in your body. Without enough insulin, sugar (glucose) can't enter your cells for energy. Your blood sugar level rises, and your body begins to break down fat for energy. This produces toxic acids known as ketones. Left untreated, diabetic ketoacidosis may cause you to lose consciousness. Eventually, untreated diabetic ketoacidosis can be fatal.
Diabetic ketoacidosis is most common in people who have type 1 diabetes, but people who have type 2 diabetes may develop diabetic ketoacidosis, too. In fact, in a few cases diabetic ketoacidosis is the first sign that a person has diabetes. If you have diabetes or you're at risk of diabetes, learn the warning signs of diabetic ketoacidosis — and know when to seek emergency care.
