After developing gestational diabetes, it is not a certainty that you will develop diabetes, but the chances of developing diabetes increase significantly. Gestational diabetes is diabetes diagnosed by oral glucose tolerance test at 24-28 weeks of pregnancy. Gestational diabetes requires diabetic diet and exercise therapy. When diet and exercise therapy are ineffective, it is necessary to choose an appropriate insulin treatment plan under the guidance of a doctor to maintain good control of blood glucose during pregnancy, so as to avoid abnormal fetal development and the occurrence of adverse pregnancy outcomes. Gestational diabetes requires a review of blood glucose at 42 days after delivery to reassess the diagnosis of diabetes. Some gestational diabetes can return to normal, some gestational diabetes can transform into abnormal glucose tolerance, and a small percentage of gestational diabetes continues to maintain elevated blood glucose and becomes diabetic. Therefore, people with gestational diabetes are at high risk for diabetes, and although they do not necessarily develop diabetes after having gestational diabetes, their chances of developing diabetes are much higher than normal.
