Diabetic ketoacidosis is a serious, life-threatening complication of high blood sugar.
It must be treated immediately. If you have ketoacidosis, you may go into a diabetic coma. If you have diabetes and don't have proper treatment for it, you may develop this very dangerous complication called ketoacidosis. This condition is called hyperglycemia. Hyperglycemia happens when you do not have enough insulin to get sugar out of your blood and into your cells.
