"What actions can lead to miscarriage?"

There is generally no definitive statement on "what actions cause miscarriage." However, during pregnancy, engaging in certain activities may elevate the risk of miscarriage, such as those that increase abdominal pressure, involve rapid and intense movements, cause strong vibrations, lead to oxygen deprivation, or involve specific body positions or movements. Here are the specifics:

1. Exercises Increasing Abdominal Pressure

Activities like squats and leg presses that increase abdominal pressure can stimulate uterine contractions, especially during early pregnancy when the embryo implantation is not firmly established. This increase in abdominal pressure may trigger uterine contractions, ultimately leading to miscarriage.

2. Rapid and Intense Movements

Sports requiring rapid bursts of energy, such as badminton, tennis, sprinting, and long jumping, can also stimulate uterine contractions and increase the risk of miscarriage.

3. Exercises with Strong Vibrations

Activities like horseback riding and rope skipping involve significant up-and-down movements. When these movements are too vigorous, they can potentially cause miscarriage.

4. Exercises Leading to Oxygen Deprivation

Activities like diving can cause oxygen deprivation in pregnant women when oxygen supply is inadequate, which may induce miscarriage.

5. Special Body Positions or Movements

Prolonged lying on one's back or sudden bending can increase abdominal pressure, affecting the safety of the fetus within the uterus.

The aforementioned actions may increase the risk of miscarriage by raising abdominal pressure, stimulating uterine contractions, causing bodily vibrations, or leading to oxygen deprivation. Pregnant women should avoid these actions during pregnancy to ensure the health of both mother and baby. Additionally, they should maintain good lifestyle habits and a positive mindset, undergo regular prenatal checkups, and promptly consult a healthcare professional in case of doubts or discomfort.
