Which of the following is a consequence of uncontrolled diabetes mellitus? Group of answer choices All of the above The liver produces glucose by gluconeogenesis Protein breakdown occurs and amino acids are catabolised. Fatty acid mobilisation from triglycerides increases. Ketone body production increases, lowering the blood pH
