Generally speaking, the answer is no. Gestational diabetes is common and typically goes away on its own.
Like other types of diabetes, gestational diabetes causes high blood sugar, which can affect your pregnancy and your baby’s health. Any complication is concerning, but the good news is that you can control gestational diabetes by eating healthy foods, exercising, and, if necessary, taking medication. Blood sugar usually returns to normal soon after delivery.
There is no way to prevent gestational diabetes with 100 percent certainty, but the more healthy habits you can adopt before pregnancy, the better. The same habits may reduce your risk of having gestational diabetes in future pregnancies or developing Type 2 diabetes down the road. Those healthy habits include:
eating foods high in fiber and low in fat and calories
staying active, with a goal of 30 minutes of moderate activity most days of the week
avoiding excess weight gain (which is most easily accomplished by healthy eating and staying active)
