Lower back pain and pelvic pain are incredibly common among pregnant women, as the body’s center of gravity shifts to accommodate a growing belly. A pregnancy back brace alleviates the strain put on abdominal muscles, lower back, hips and the pelvic floor as pregnancy progresses, relieving the aches and pains that go along with it. It can also help improve circulation, especially in the second and third trimester. As your baby bump grows, a pregnancy back brace can help lift the weight off of the blood vessels that flow to the lower extremities, promoting good circulation and reducing fatigue in the legs and feet.
