Gestational diabetes is a type of diabetes that is somewhat unique. People in this category usually have normal blood glucose levels before pregnancy. However, between the 24th to 28th week of pregnancy, an oral glucose tolerance test is conducted, and if high blood glucose levels are detected, a diagnosis of gestational diabetes is made. For such patients, it is generally recommended to conduct another oral glucose tolerance test 6-8 weeks postpartum. If the results are normal at this time, it indicates that the patient does not have diabetes. However, a very small proportion of individuals may still exhibit high blood glucose levels after the 6-8 week postpartum re-examination. In such cases, continued treatment for diabetes might be necessary.
