What causes back pain during pregnancy?
The following changes during pregnancy can lead to back pain:
How do my back muscles become strained during pregnancy?
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.
How can weakened abdominal muscles affect my back during pregnancy?
Your abdominal muscles support the spine and play an important role in the health of the back. During pregnancy, these muscles become stretched and may weaken. These changes also can increase your risk of hurting your back when you exercise.
How can pregnancy hormones contribute to back pain?
To prepare for the passage of the baby through the birth canal, a hormone relaxes the ligaments in the joints of your pelvis. This loosening allows the joints to become more flexible, but it also can cause back pain if the joints become too mobile.

Back pain is a symptom of preterm labor, and it also can be a sign of a urinary tract infection. Contact your health care professional right away if you have a fever, burning during urination, or vaginal bleeding in addition to back pain.
