Introduction
Under normal circumstances, the typical fetal movement frequency at 35 weeks is 3–5 movements per hour, or 30–40 movements per 12 hours. If fetal movements exceed 5 times per hour or 40 times per 12 hours, this is considered excessive fetal activity, which may indicate fetal hypoxia. Prolonged oxygen deprivation can slow the fetus's growth and development, and in severe cases, may even lead to developmental arrest.
Under normal circumstances, the typical fetal movement frequency at 35 weeks of gestation is 3–5 movements per hour, or 30–40 movements in 12 hours. If fetal movements exceed 5 times per hour or 40 times in 12 hours, this is considered excessive fetal activity, which may indicate fetal hypoxia (oxygen deficiency). The detailed explanation is as follows:
At 35 weeks, pregnancy has entered the third trimester. During this stage, normal fetal movement typically occurs at a rate of 3–5 times per hour, or 30–40 times in 12 hours. When fetal hypoxia is present, increased fetal movement is usually observed, with frequencies exceeding 5 movements per hour or 40 movements in 12 hours. Over time, this may progress to reduced fetal movements, fewer movements, or even cessation of movement altogether—this pattern is a classic sign of fetal oxygen deprivation and should be taken seriously. Prolonged fetal hypoxia can slow the rate of fetal growth and development, and in severe cases, may lead to developmental arrest.
In summary, frequent fetal movements at 35 weeks represent an abnormal condition. Pregnant women are advised to monitor fetal movement regularly. If abnormal patterns persist, prompt medical evaluation at a reputable healthcare facility is recommended.
