Physical Changes During Pregnancy
Joints and muscles
The joints and ligaments (fibrous cords and cartilage that connect bones) in the woman’s pelvis loosen and become more flexible. This change helps make room for the enlarging uterus and prepare the woman for delivery of the baby. As a result, the woman’s posture changes somewhat. Backache in varying degrees is common because the spine curves more to balance the weight of the enlarging uterus. Avoiding heavy lifting, bending the knees (not the waist) to pick things up, and maintaining good posture can help. Wearing flat shoes with good support or a lightweight maternity girdle may reduce strain on the back.
