Most patients with gestational diabetes gradually return to normal 1-2 weeks after delivery, while some patients who fail to recover for a long time will need to be tested and treated accordingly. About 1/3 of patients are at risk of progressing to diabetes, so it is important to monitor blood glucose levels after delivery. Gestational diabetes is mainly caused by abnormal glucose metabolism during pregnancy. After pregnancy, pregnant women should pay attention to reasonable supplementation of nutrition and should not overconsume energy, which will lead to elevated blood sugar. And the hormone metabolism in the body after pregnancy is changed compared with that before pregnancy, so the incidence of diabetes will be increased accordingly. In addition, there is also a situation where a person already has diabetes before pregnancy, and the combined pregnancy is called gestational diabetes. This condition can also lead to abnormal pregnancies such as placental abruption if the blood sugar is not controlled. Most cases of gestational diabetes can return to normal 1-2 weeks after delivery, but if it does not return for a long time after delivery, the OGTT needs to be repeated 5-6 weeks after delivery to check the blood glucose status. If the test is abnormal, treatment can be taken accordingly. Gestational diabetes should be of great concern to the public and pregnant women should pay attention to their diet during pregnancy and should not be over-nourished.
