What causes back pain during pregnancy?

Although back pain during pregnancy is considered normal or a symptom of pregnancy, most women want to know what causes it. Back pain during pregnancy is affected by a variety of reasons. Some women have reported back pain as part of their early symptoms of pregnancy. Some women are more at risk for back pain during pregnancy because or current weight issues, inappropriate body postures, or current back issues. Outside of these factors, here is a list of potential causes of back pain or discomfort during pregnancy:

  • Increased hormone levels – hormones released during pregnancy allow ligaments in the pelvic area to soften and the joints to become looser in preparation for the birthing process of your baby; this shift in joints and loosening of ligaments may affect the support your back normally experiences
  • Center of gravity – your center of gravity will gradually move forward as your uterus and baby grow, which causes your posture to change
  • Additional weight – your developing pregnancy and baby create additional weight that your back must support
  • Posture or position – poor posture, excessive standing, and bending over can trigger or escalate the pain you experience in your back
  • Stress – stress usually finds the weak spot in the body, and because of the changes in your pelvic area, you may experience an increase in back pain during stressful periods of your pregnancy

  • Severe back pain
  • Increasingly severe or abrupt-onset of back pain
  • Rhythmic cramping pains; this could be a sign of preterm labor

Severe back pain may be related to pregnancy-associated osteoporosis, vertebral osteoarthritis, or septic arthritis. These are not common, but it is something your health care provider will examine if you are experiencing severe back pain.
