Who to see

Health professionals who can diagnose and treat gestational diabetes include:

After you are diagnosed with gestational diabetes, you may be referred to other health professionals who can help you understand what gestational diabetes means. These may include:

  • A certified diabetes educator (CDE). A CDE is a registered nurse, registered dietitian, doctor, pharmacist, or other health professional who has training and experience in caring for people who have diabetes. A CDE can help you understand how to take care of yourself and help you adjust to living with gestational diabetes.
  • A registered dietitian. All women who have gestational diabetes need to see a registered dietitian for help choosing the best foods. Follow-up visits with a dietitian are helpful if you need to change your eating habits.
