When the fetus is two weeks older than the actual gestational week, the possible effects include errors in calculating the due date, difficulties in delivery, and an increased risk of gestational diabetes in the pregnant woman. It is recommended to have regular maternity checkups to clarify the causes according to the specific situation and to carry out targeted treatment. If the fertilized egg is formed and the embryo is laid early, the fetus may appear two weeks older than the actual gestational week. Since the due date is usually calculated according to the last menstrual period, the due date may be earlier, so you need to make regular maternity checkups and combine the due date with the ultrasound examination results. If the gestational week suggested by ultrasound is more than 1 week different from the gestational week projected according to the last menstrual period, the gestational week should be rechecked and the gestational week projected by ultrasound and the due date should prevail. When there is fetal over-nutrition, there may also be a situation where the gestational week is two weeks older than the actual gestational week, which may cause labor difficulties and lead to perineal tears in women, as well as an increased risk of post-operative infection. During pregnancy, you need to control your diet, you can eat more fresh vegetables and fruits appropriately, less fried food, and supplement nutrition in moderation; reasonably strengthen your exercise, such as yoga, slow walking, and walking after meals, and develop a regular exercise program to control the growth of fetal weight. In addition, a fetus larger than the gestational week may also indicate that the pregnant woman is at risk of gestational diabetes, which not only increases the risk of miscarriage and premature birth, but also may lead to fetal malformation and fetal growth restriction. Also after the delivery of the fetus, the risk of neonatal hypoglycemia and respiratory distress syndrome is higher, and pregnant women will have an increased incidence of preeclampsia, infection, and obstructed labor. It is important to control the carbohydrate intake during pregnancy, and if the effect of regulating blood sugar is not good, medication can be applied to control it.
