How to Use the Gestational Diabetes Risk Checker
Gestational diabetes is a form of high blood sugar first identified during pregnancy, and it can affect both parent and baby, which is why timely screening matters. This checker converts well-established risk factors — age, pre-pregnancy BMI, family history, and pregnancy history — into a score, then shows a risk level and recommended screening timing based on ACOG and ADA guidance.
Age 35 or older, pre-pregnancy obesity (BMI 30 or higher), a parent or sibling with diabetes, a prior gestational diabetes diagnosis, a previous baby over 9 lb, and PCOS are all recognized risk factors — the more that apply, the higher the score and risk level. Under U.S. guidelines, every pregnant person is generally screened between 24 and 28 weeks with a 50g, 1-hour glucose challenge test, regardless of risk factors; those with multiple risk factors may be offered earlier testing at their first prenatal visit at their provider's discretion.
This tool simply totals known statistical risk factors — it is not a diagnostic test and cannot confirm or rule out gestational diabetes. Even a low score does not mean you can skip standard screening at 24-28 weeks, and a high score does not mean you have the condition. Use this result only as a conversation starter with your OB-GYN or midwife, who can advise on the right testing approach and timing for your specific situation.
Frequently Asked Questions
Most people are screened between 24 and 28 weeks of pregnancy with a 50g, 1-hour glucose challenge test. If you have several risk factors, such as obesity or a family history of diabetes, your provider may recommend earlier screening at your first prenatal visit, per ACOG guidance.
No. This is a self-check for awareness only — even with a low score, standard prenatal care still includes screening at 24-28 weeks (or earlier if your provider recommends it based on your full history).
