The main cause of back pain during pregnancy is strain on your back muscles. As your pregnancy progresses, your uterus becomes heavier. Because this increased weight is carried in the front of your body, you naturally bend forward. To keep your balance, your posture changes. You may find yourself leaning backward, which can make the back muscles work harder. This extra strain can lead to pain, soreness, and stiffness.
Get regular exercise. Exercises for the back strengthen and stretch muscles that support your back and legs and promote good posture. They not only ease back pain but also help prepare you for labor and childbirth. For more information:
