Which factor best predicts future risk of type 2 diabetes in someone with prior gestational diabetes?

• A. History of diabetes in a first-degree relative
• B. History of gestational diabetes itself
• C. Current body mass index
• D. Maternal age over 35

Answer: (B)

Having had gestational diabetes is the strongest predictor of future type 2 diabetes. GDM reveals an underlying tendency toward glucose intolerance and beta-cell dysfunction, so the risk of progressing to type 2 diabetes after pregnancy is substantially elevated and persists for many years. While a family history of diabetes, higher current body mass index, and older maternal age can raise risk, none predict future diabetes as accurately as the prior GDM episode itself. This is why the history of gestational diabetes is the best predictor among the options.
