The job duties of a certified diabetes educator (CDE) involve educating patients who have prediabetes or have received a diabetes diagnosis regarding lifestyle changes, prevention strategies, and disease management practices. Responsibilities include working with a diabetic patient to help them understand dietary needs, medication dosages, and diabetes monitoring practices such as testing blood sugar levels. A CDE follows up with patients to assess their ability to manage their diabetes. They may also collect patient data and share progress reports with other medical professionals. The qualifications you need to become a certified diabetes educator vary but include certification through the National Certification Board for Diabetes Educators.
