Patients must learn to monitor blood glucose with frequent finger-prick tests, noting the level and trends in the results (Sarkar et al 2010). Damage to the eyes, kidneys, nerves, heart and blood vessels can occur if high blood glucose levels are not controlled. Patients need to be confident when giving self-administered insulin injections, by giving themselves the proper dose and being aware of the time it needs to be done.
Diabetics should monitor their caloric intake and blood glucose levels to avoid hyperglycemic and hypoglycemic states.
