About 1 in 10 pregnant people in California get gestational diabetes. Detecting and managing it early can help ensure a healthy pregnancy and baby.
If you're pregnant or think you might be, talk with your health care provider about gestational diabetes. Testing for gestational diabetes usually happens between 24 and 28 weeks of pregnancy, or earlier if needed.
