Frequent uterine contractions may be caused by the frequent movement of the fetus in the uterus, which stimulates the uterine wall, or by external stimulation when the pregnant woman is overworked or overstressed. If you have frequent contractions, you should rest in bed, do not exercise strenuously, and have an ultrasound to check the condition of the fetus. If the fetus has ischemia and hypoxia in the uterine cavity, it will easily stimulate the uterus and cause uterine contractions, which requires timely oxygen intake to improve the symptoms. If the fetus has severe ischemia and hypoxia in the uterine cavity, it may lead to the possibility of fetal asphyxia, and this symptom should be improved as soon as possible. If the oxygen intake does not improve near the due date, a timely cesarean section is needed to terminate the pregnancy.
