If a diabetes mellitus patient continually has high blood glucose, what is likely to happen to the nervous system, and what are the possible outcomes?
What will be an ideal response?
With too much glucose present, the blood-brain barrier cells may remove glucose transporters from the patient's membranes. If blood glucose drops due to insulin therapy, the brain neurons may be unable to obtain sufficient glucose to function or remain alive. This can lead to a comatose state or even death.
