The three things that marginal placenta should avoid the most are:

Pregnant women with placenta previa should pay special attention to avoiding vigorous exercise, sexual activity, and prolonged standing. Marginal placenta refers to the condition where the lower edge of the placenta is close to or covers the cervical opening, which may increase the risk of late pregnancy bleeding. It should be diagnosed through ultrasound examination and regularly monitored.

1. Intense exercise

High intensity activities such as running, jumping, or carrying weight may increase abdominal pressure, leading to an increased risk of placental and uterine wall detachment. It is recommended to choose low-intensity exercises such as walking and yoga for pregnant women, with a single session lasting no more than 30 minutes. If there is lower abdominal bloating or vaginal bleeding, stop moving immediately and seek medical attention.

2. Sexual activity

Uterine contractions caused by sexual arousal may induce placental abruption, which should be completely prohibited after mid pregnancy. Mechanical stimulation during sexual intercourse may directly damage placental tissue near the cervix, leading to painless bleeding. Those diagnosed with borderline placenta after 28 weeks of pregnancy should strictly follow medical advice and abstain from sexual activity.

3. Long term standing

Prolonged standing for more than 1 hour can worsen the tendency of uterine prolapse and increase the pressure on the blood vessels at the edge of the placenta. It is recommended to work in a sitting position for 40 minutes, get up and move for 5 minutes, and use a pillow to elevate the buttocks during sleep. Patients with combined pain of pubic symphysis separation need to use a pelvic girdle to reduce compression. Pregnant women with marginal placenta should rest in the left lateral position for no less than 2 hours a day and supplement with foods rich in iron and vitamin C, such as beef, spinach, oranges, etc., to prevent anemia. Monitor fetal movements weekly and avoid lifting heavy objects weighing more than 5 kilograms. If there is bright red vaginal bleeding, persistent uterine contractions, or abnormal fetal movement, immediate emergency treatment is required. Regular prenatal check ups track changes in the position of the placenta through ultrasound, and in most cases, the position of the placenta moves up with gestational age.
