Whether the strong fetal movement at 33 weeks of pregnancy is normal or not depends on the specific performance 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 more than 30-40 times. Some fetuses move significantly, as long as the fetal movement is regular, rhythmic, and does not change much, it means that the fetal development is relatively normal. Fetal movement can also increase significantly when the external temperature rises and the pregnant woman’s activity increases, if it remains within the normal range, there is no need to worry excessively. In abnormal cases, the number of fetal movements may increase abnormally or the fetus may show intermittent agitation with fetal heart rate ≥160 beats per minute, which may indicate acute intrauterine ischemia, hypoxia, fever, hypoglycemia, disease stimulation, etc. At this time, pregnant women should go to the hospital as soon as possible for relevant examinations and cooperate with the treatment to relieve the fetal distress state. In order to ensure normal fetal movement, pregnant women should pay more attention to rest, not too fatigue, diet should be diversified, ensure that there is enough carbohydrate, eat more vegetables, fruits and potatoes, appropriate increase the intake of milk, beans or their products, and at the same time can reasonably add fresh seafood, poultry meat, etc. to the diet.
