Diabetic ketoacidosis (DKA) is a very serious complication of type 1 diabetes. It is always a medical emergency and requires rapid medical attention to prevent further damage to a patient, if left untreated it can potentially lead to death. DKA occurs when there is not enough insulin in the body to supply sugars to the body's cells. In order to give its cells enough energy to survive, the body begins to produce acidic ketone bodies which are then used to feed energy to the cells.
