Yes! The decompensation rate for persons with gestational diabetes to full blown diabetes is about 5%/yr. So, in 10 years, 50% of the ladies will have diabetes. You can influence this. A study done a few years ago called the Diabetes Prevention Trial (DPT) showed that lifestyle changes (diet, wt. loss, & exercise) would reduce the rate of progression to full blown diabetes over the course of the study by 60%. If you have a YMCA near by, they now have this program & can help you for a very low price. I can't answer your question of your chances beyond this without knowing more about you, such as your wt & ht (BMI) & how severe your gestational diabetes was. Just based on national figures, though, the chances are as above, about 5%/yr. Age, body wt., family history of diabetes, etc., can modify this rate both ways. Get a good diet & exercise program, continue to check your blood sugar levels both fasting & after meals on occasion, & get a HbA1c test whenever your physician does other blood testing. Work at it and you can put it off.
