Why Is Fetal Movement Frequently Occurring at 21 Weeks?

Frequent fetal movement at 21 weeks may be caused by physiological factors, fetal hypoxia, anemia, and other reasons. It is recommended to seek medical attention and receive targeted treatment based on the underlying cause. Details are as follows:

1. Physiological Factors: Sudden emotional excitement, excessive fatigue, or overexertion in pregnant women may lead to frequent fetal movement. Generally, normalizing emotions and taking a short rest can restore normal fetal movement.

2. Fetal Hypoxia: At 21 weeks of pregnancy, there may be a risk of umbilical cord缠绕 around the neck, affecting blood flow and causing fetal hypoxia, which in turn leads to frequent fetal movement. It is recommended to seek medical advice and follow instructions to adopt special positions to allow the baby to self-adjust and relieve the umbilical cord缠绕.

3. Anemia: Some pregnant women may experience severe pregnancy reactions in the early stages, leading to reduced food intake, insufficient nutrition, and severe anemia. This results in inadequate blood oxygen levels, causing the fetus to receive insufficient oxygen and exhibiting frequent fetal movement. Treatment may include oral administration of ferrous lactate oral solution, compound Ejiao syrup, etc., as prescribed by a doctor.

During pregnancy, the diet should be as diversified as possible, with balanced intake of various foods to supplement nutrients. Avoid excessive fatigue and ensure adequate rest.
