Back Pain During Pregnancy
January 17th, 2010Back pain in pregnant women is a very common complaint. In fact, as many as 80% of pregnant women will have back pain at some time during their pregnancy. There are several types of back pain that occur among expectant mothers, but low back pain is the most common. But why does your low back hurt during pregnancy?
Back Pain can occur for a number of reasons, which can be reduced to two main issues: hormones and postural changes.
During pregnancy, your body produces a veritable cocktail of hormones. Among these is a hormone called relaxin. The primary role of relaxin is to loosen the joints and ligaments in your body in order to help them stretch and widen. This allows your body to more easily make room for your baby inside of your pelvis. And, when the time comes for your baby to be born, the hormone relaxin will have helped the joints of your pelvis relax and stretch enough for your baby’s shoulders to pass through your pelvic bones.
