Diabetic Ketoacidosis (DKA) is a dangerous health condition and is completely preventable. If you have Type 1 diabetes, high blood glucose can lead to DKA. When the body cannot use sugar for energy because of lack of insulin, the body breaks down fat for energy and ketones are made. Ketones are the acids or toxins produced when blood glucose rises in the absence of insulin. Large amounts of ketones in the blood cause the life-threatening problem called diabetic ketoacidosis. When high levels of ketones are in the blood, the ketones spill into the urine, just as sugar does. Your whole body becomes too acid: in other words, you have acidosis (BC Health)
