discuss the pathology of a condition in which glucose regulation (in the blood and/or urine) presents problems for patients. what causes this condition? how is glucose monitoring accomplished, and how is it indicative of the patient's level of proper biological function? explain on a cellular level how this glucose imbalance arises. also explain the science behind the monitoring technique. most importantly, what measures can be taken by patients to correct for this glucose imbalance in the long term? why do these measures work?
