Back pain in pregnancy causes, treatment, and prevention


Pregnancy is undoubtedly a wonderful thing. But in these 10 months of pregnancy, pregnant women are likely to experience more or less pain in one way or another. Back pain in pregnancy is one of the common symptoms during this period.

After the pregnancy enters the middle stage, the stable joints in the pelvis begin to relax and open, and the ligaments of the spine and joints are relaxed, preparing for childbirth. At this time, some pregnant moms will feel back pain. In addition, as the gestation month progresses, the uterus becomes larger and the center of gravity gradually moves forward. In order to maintain the balance of gravity when standing or walking, pregnant mommy can only lean back to maintain posture. This posture increases the load on the ligaments and spine of the lower back, which can also cause or aggravate low back pain. In addition, the enlargement of the uterus against the nerves of the lower back is another cause of low back pain. At the end of pregnancy, the phenomenon of low back pain is more obvious. There are also some diseases that can cause back pain.
