      What causes lower body pain during pregnancy? ? Some people will feel pain in their "lower body" after pregnancy, even turning over or cough , defecation is also painful, this situation is caused by pubic symphysis separation.

      The pubic bone has two left and right pieces, which together form the front edge of the pelvis. The pubic bones are connected by fibrocartilage and reinforced by ligaments, making them difficult to move. After pregnancy, due to the influence of hormones, the two pubic bones are slightly separated, causing fetus Will give birth smoothly in the future. However, if the separation of the pubic bones is large, it will cause traction pain when walking, especially when climbing stairs. Because when the hind legs touch the ground when going upstairs, the center of gravity of the body is tilted to one side, and the left and right pubic bones are misaligned, which pulls the fibrocartilage and ligaments, causing pain. If the separation is severe, the ligaments are torn, and there is edema, you will not be able to walk. Although the pubic symphysis is somewhat separated after pregnancy, only a few people experience pain. The pain is mild, tolerable, and does not affect work and life. However, pregnant women still need to avoid heavy physical labor and walking for long periods of time. Bed rest is required when the pain is severe. The best sleeping position is on the left side.

      Will pubic symphysis separation affect childbirth? Generally speaking, if the condition is mild and the fetus is not large, it will not affect delivery. If the condition is severe and the fetus is too large, a caesarean section should be performed. After the fetus is delivered, the estrogen level drops, the pubic symphysis gradually closes and returns to its original shape, and the pain disappears. However, during maternity leave, you should still walk less and sleep more, and do not do heavy physical labor. 》》》 Six types of pregnant women who should not drink milk
