Back and pelvic pain is common in pregnancy and affects around 50-80% of pregnant women. This pain is associated with the biochemical and structural changes in the body that occurs during pregnancy, after giving birth, and if breastfeeding.
These changes can alter posture and weaken muscle support.
During pregnancy the body produces the hormone relaxin, which increases during the 1st trimester and in the final weeks of pregnancy. This hormone as the name suggests, “relaxes” or loosens the muscles, tendons, and ligaments in the body to allow the body to accommodate the growing baby.
The increased weight of the belly tilts the pelvis forward causing the back to arch further to maintain balance. This “hyperlordotic” position can then cause the joints in the back to become stiff and irritated as the normal lubrication and movement is reduced.
