As a certified diabetes educator (CDE), your job is to support the health of your patients through diabetes prevention and management. To accomplish this, you may spend time talking with patients about prediabetes, discussing care options, and deciding on a treatment program that ensures the best continuing quality of life. Diabetes educators often provide personal instruction, give nutritional counseling, collect data from patients, work with other caregivers, attend outreach events, and evaluate existing teaching programs to see if they can be improved. Most patients also need to learn how to administer insulin and self-monitor blood glucose levels, so providing that education is essential to your success.
