Therefore, each ketone body loses a proton (H+) as it circulates in the blood, which lowers the pH.] Also, in uncontrolled T1D, urinary loss of glucose and ketone bodies results in dehydration. Therefore, the increased number of H+ circulating in a decreased volume of plasma can cause a severe acidosis (ketoacidosis, Fig. 16.24) known as diabetic ketoacidosis (DKA).] A frequent symptom of DKA is a fruity odor on the breath, which results from increased production of acetone. Ketoacidosis may also be seen in cases of prolonged fasting (see p. 330) and excessive ethanol consumption (see p. 318).
