During pregnancy, women are less active and less active, the gastrointestinal motility of pregnant women is significantly slowed down, coupled with the change in hormone levels in women’s bodies during pregnancy, progesterone and relaxin will increase in large amounts, making the blood vessels dilate. In late pregnancy, due to the increase in the uterus, the intra-abdominal pressure rises, and it is easy to have constipation, hemorrhoids, and other difficulties in defecation. If laxatives are used improperly, the risk of miscarriage is often increased. The high blood sugar during pregnancy can promote the growth of the fetus in the uterus, which can lead to the creation of a huge fetus, and a huge fetus can seriously lead to obstructed labor and amniotic fluid embolism. During pregnancy and postpartum, the body resistance of pregnant women decreases and the uterine cavity environment is poor, so various germs are likely to take advantage of the situation. Therefore, during this period, it is easy to lead to gynecological inflammation. Therefore, the first thing you should do during pregnancy is to adjust your lifestyle through: 1. Eat high fiber foods every day: including whole grain cereals and breads, brown rice, beans and fresh fruits and vegetables; 2. Drink plenty of water: try to drink 2000~2400ml of water or other beverages every day; 3. Exercise regularly: walking, swimming, riding stationary bicycles and yoga can all promote health. These are helpful to enter the intestinal peristalsis, control blood sugar and improve the immunity of the body. Probiotics, whether from food or supplements, can help the digestive system to function more efficiently. Probiotics increase the beneficial bacteria in the intestinal tract, which can help balance nutrient absorption, promote intestinal motility, improve the body’s immunity, regulate blood sugar, prevent infections and allergies, and other functions. In current studies on the use of probiotics during pregnancy, no association has been found between the use of probiotics and miscarriage or any form of fetal malformation. Therefore, probiotics can be taken during pregnancy to improve constipation, hemorrhoids, high blood sugar during pregnancy and to strengthen the immunity of pregnant women after delivery and to prevent the occurrence of gynecological inflammation after delivery. And now the incidence of postpartum depression is increasing, research found that depression and intestinal flora disorders are closely related, pay attention to the adjustment of intestinal flora during pregnancy, but also help to reduce the occurrence of postpartum depression. Therefore, it is possible to take probiotics during pregnancy.
