What is a primary symptom of diabetic ketoacidosis?

DKA: A metabolic emergency for patients primarily with type 1 diabetes, DKA symptoms include those of high blood sugars initially. As the ketones build up, patients may have a fruity odor on the breath, get abdominal pain & vomit. Because they're already urinating a lot, dehydration can get bad. Some may breathe fast, get headaches, have altered consciousness. Without proper treatment, death imminent.
