Ketones - Ketones, or ketone bodies, are substances produced by normal liver activity, and used by muscle tissue. In uncontrolled diabetes, the process becomes unbalanced and ketones can accumulate in the blood, pass through the urine, and ultimately result in diabetic ketoacidosis (DKA).
Ketonuria - Having ketone bodies in the urine; a warning sign of diabetic ketoacidosis (DKA).
Ketosis - A condition of having ketone bodies build up in body tissues and fluids. The signs of ketosis are nausea, vomiting, and stomach pain. Ketosis can lead to ketoacidosis.
