Whether or not it is normal for the fetus to move a lot in 33 weeks of pregnancy depends on the specific manifestation of fetal movement. Under normal circumstances, fetal movement is not less than 3-5 times an hour, and the number of obvious fetal movements in 12 hours is 30-40 times or more. Some fetuses have obvious fetal movement, as long as the fetal movement is regular, rhythmic, and does not change much, it means that the development of the fetus is relatively normal. Fetal movement can also increase significantly when the external temperature rises and the activity level of the pregnant woman increases, if it is still within the normal range, there is no need to worry too much. Under abnormal circumstances, the number of fetal movements may increase abnormally or the fetus may show unintermittent agitation, accompanied by a sustained fetal heart rate of ≥160 beats per minute, which may indicate acute intrauterine ischemia, hypoxia, fever, hypoglycemia, disease stimulation, and so on. At this time, pregnant women should go to the hospital as soon as possible to do relevant examinations, cooperate with the treatment, and relieve the state of fetal distress. In order to ensure normal fetal movement, pregnant women should pay more attention to rest in general, do not be too fatigue, meals should be diversified to ensure that there are enough carbohydrates, eat more vegetables, fruits and potatoes, and appropriately increase the intake of milk, beans or their products, at the same time, can be reasonably added to the diet of fresh seafood, poultry and meat, and so on.
