What actions can easily cause a miscarriage?

Generally, during pregnancy, engaging in vigorous exercise, abdominal pressure-inducing movements, rapid changes in body position, complex balance-related activities, and actions related to heavy physical labor may increase the risk of miscarriage and should be avoided as much as possible during pregnancy. Detailed explanations are as follows:

1. Vigorous exercise: Such as fast running, jumping, high-intensity interval training, long-duration sprinting, and similar activities. These types of movements cause significant physical jolting, which can abruptly increase abdominal pressure, potentially stimulating uterine contractions and increasing the risk of falling, thus affecting the stability of embryonic implantation.

2. Abdominal pressure-inducing movements: Such as squatting to the lowest position, bending to lift heavy objects, push-ups with the abdomen facing downward, and large twisting movements while wearing tight clothing. These types of movements directly compress the abdomen, possibly pressing on the uterus and affecting blood supply to the placenta.

3. Rapid changes in body position: Such as suddenly sitting up from a lying position, quickly bending and then standing upright, or rapidly rotating the body. Sudden postural changes may trigger orthostatic hypotension, leading to insufficient cerebral blood supply, which could cause dizziness and instability while standing.

4. Complex balance-related movements: Such as standing on tiptoes for a long time, standing on one foot, and advanced balance postures in yoga. These types of movements require maintaining a high level of body balance. Due to hormonal changes during pregnancy that cause joint laxity and decreased balance ability, pregnant women are more prone to falls, and abdominal impact during a fall may lead to miscarriage.

5. Movements related to heavy physical labor: Such as carrying heavy objects for prolonged periods, repeatedly bending to mop the floor, or climbing to high places. Heavy physical activities can cause excessive fatigue, sustained muscle tension, and prolonged high levels of abdominal pressure, which may induce uterine contractions and pose a significant threat to pregnancy safety.

Pregnancy-related exercise should primarily be mild and gentle, such as walking or gentle prenatal yoga. The intensity and duration of exercise should be controlled, avoiding the above high-risk movements. Regular prenatal checkups are also essential to monitor the health status of both mother and fetus.
