Failure to control diet and increase exercise in time during late pregnancy may result in an oversized fetus, which will increase the chances of obstructed labor as well as cesarean delivery, so it is important to encourage pregnant women to increase their activity appropriately during late pregnancy. In the absence of contraindications, it is recommended to walk 6,000-10,000 per day, usually half an hour after a meal. Activity is not allowed if the pregnant woman has placenta praevia, vaginal bleeding or abdominal pain. If you experience frequent contractions or vaginal bleeding while walking, seek medical attention. Moderate walking during pregnancy has the following benefits: 1, to promote childbirth: pregnant women in late pregnancy appropriate walking can promote the fetus into the pelvis, while the fetus in the role of gravity can stimulate the cervix, conducive to cervical softening and opening up, and thus conducive to childbirth; 2, weight control: due to late pregnancy fetal weight growth is faster, if pregnant women do not control diet and increase exercise in a timely manner, may cause the fetus too large, and thus increase the natural delivery in The chance of difficult delivery and cesarean section will increase.
