“Does gestational diabetes go away after pregnancy?”

Usually yes, but you need to be rechecked 3 months after delivery to confirm that it did. Then you need to keep the weight down and exercise to prevent type 2 diabetes.

It may or may not. You should have follow-ups periodically with your doctor.

The risk of gestational diabetes to become diabetes later in the life is 10%-12%.

It can go away after your pregnancy, but you still will have a higher risk of having diabetes in the future. If you maintain good eating habits and exercise you can delay getting diabetes in the future, or may not even get it.
Once you deliver your baby, you need to get tested 6-12 weeks after delivery so your doctor can see if you still has diabetes or if it went away after

It may or may not. Gestational diabetes like all diabetes has a genetic component that never goes away. The body needs more insulin during pregnancy so if you have the genetic factor or the environmental factors(obesity & others) you may produce enough insulin for your own needs but not enough for the needs of pregnancy. Af,during the pregnancyter pregnancy you may go back to a state of producing enough insulin to meet your needs so it will seem the diabetes has gone away. But the genetic factor is still there so if you get pregnant again it will reappear. Also you may have, during the pregnancy, lost more insulin producing ability & the diabetes will stay. Even if you go back to normal after the pregnancy remember you still have the gene & the diabetes can progress to prediabetes or frank diabetes with time. To avoid or slow this process, since you can't change your genetics, you must eliminate the environmental influences i.e. obesity, poor eating habits, lack of exercise, etc. I hope things go well for you.
