How bad a 3 hour gestational diabetes result is having 1 high score?

Not bad: You have to have at least 2 abnormal values on a 3 hour glucose tolerance test in order to be diagnosed with gestational diabetes. However, having one abnormal value still puts you at some risk for having an abnormally large baby. It probably makes sense to limit simple carbohydrates (sugar, white flour, white rice) in your diet for the remainder of your pregnancy.

Normal: By definition, it's normal. However, most obs will reassess your risk factors and determine if repeat testing, diet modification, or finger-stick testing is helpful. Some patients develop gestational diabetes later in their pregnancy and this factors into your doc's decision process. Follow a reasonable diet & exercise program to help deter gdm or ask your OB the best course of action. Good luck.
