The 32 weeks belongs to the late gestation period, in general, the fetal weight range is 1800-2600g. However, the specific value will vary from fetus to fetus due to genetic inheritance, nutritional status and other reasons. At this time, parents should monitor the fetal weight to avoid overweight or underweight fetus.1. Overweight fetus: If the fetal weight is found to be greater than the upper limit, pregnant women are advised to be screened for gestational diabetes. A 75g glucose tolerance screening should be done to rule out the possibility of gestational diabetes. At the same time, excessive nutrient intake can also lead to overweight fetus, at this time should strictly control the diet, so as to avoid obstructed labor due to oversized fetus during delivery; 2, the fetus is too light: if the fetus is significantly smaller than the standard weight, should consider fetal growth restriction, at this time to re-check the gestational week, detect whether the pregnant woman has viral infection, and pay attention to whether the pregnant woman has gestational hypertensive disease or antiphospholipid syndrome. It is recommended that the pregnant woman should strengthen nutrition, take calcium and iron supplements, and the pregnant woman can also take DHA supplements to promote fetal brain development, and review the ultrasound after 2 weeks to note whether the fetal size has increased. Before delivery, another ultrasound is needed around 38 weeks to assess the size of the fetus. If the fetus is too large, a cesarean section is recommended to terminate the pregnancy; if the fetus is of moderate size and the mother’s pelvis is normal, a vaginal delivery can be chosen.
