Intense fetal movement before hiccups during pregnancy is usually normal, but if there is always frequent fetal movement, you need to consider the presence of an abnormality. Fetal hiccups are caused by spasm of the diaphragm, so there will be obvious fetal movement before hiccups. Pregnant women should not be overly nervous when fetal movement is noticeable, and should pay more attention to rest. Pregnant women can count the fetal movement every day, through the fetal movement to determine whether the development of the fetus in the uterine cavity is normal, three hours a day, such as morning, noon and night each set aside an hour to count the fetal movement, the number of fetal movements per hour is greater than three is normal. If the fetal movement is too frequent or the number of fetal movement is very small, you need to consider that the fetus has intrauterine hypoxia and other problems, you need to go to the hospital immediately for examination, and if necessary, need to inhale oxygen treatment.
