Fetus 40 weeks and still do not start may be normal, but do not rule out pathological factors such as the presence of cephalopelvic disproportion, placental hypoplasia, etc., can be dealt with through regular observation, moderate exercise, cesarean section and other methods.
1. Normal situation: most pregnant women experience contractions during 37-41 weeks plus 6 days of pregnancy, and 40 weeks of pregnancy is in this period, and there may be no labor, and there are no other abnormalities in the pregnant woman and the fetus during the examination. At this time, continue to observe can, but also moderate exercise, most of the 41 weeks before the start of contractions.
2. Cephalopelvic disproportion: If the pregnant woman’s pelvis is too small or the fetus’s skull is too large, resulting in the head of the fetus not being able to enter the pelvis, the fetus may not start at 40 weeks, and then a cesarean section is needed.
3. Placental hypoplasia: If the examination finds that there is placental hypoplasia and the fetus is over-mature, it will also cause the fetus not to start at 40 weeks. At this time, if there is no normal fetal position, cephalopelvic proportionality, cervical canal ripening, can be titrated to induced labor; on the contrary, the need for cesarean section.
If a pregnant woman has a 40-week fetus that does not start, it is recommended that she consult a doctor in time, under the guidance of the doctor, complete the relevant examinations, identify the cause of the disease, and symptomatic treatment.
