Why do I have back pain when I am pregnant?

Don't think that pregnancy is just pregnancy. The body will undergo changes after pregnancy that we can't imagine. First of all, as the pregnancy time gets longer, the belly begins to slowly grow larger. At this time, the first part to be compressed is the uterus, and the uterus will also cause back pain or even back soreness due to the compression. This is also a problem that many pregnant women often face during pregnancy.

Causes of back pain during pregnancy

The increased weight on the waist and abdomen leads to fatigue of the waist and back muscles: During pregnancy, as the fetus grows, the center of gravity of the expectant mother's abdomen moves forward, and the weight on the waist and back muscles increases. In the later stages of pregnancy, the expectant mother's belly becomes bigger and bigger, and this situation becomes more obvious. The waist and back muscles are prone to fatigue, resulting in symptoms of waist and back pain.

The secretion of relaxin affects the strength support of the pelvis and the quality of tissues such as bones, muscles and ligaments: relaxin is a group of polypeptides similar to "insulin". Under normal circumstances, women's relaxin is secreted by the corpus luteum of the ovary, and the secretion of relaxin increases during pregnancy. This is mainly to stimulate breast development, relax the skeletal muscle system of the whole body, change the curvature of the lumbar spine and the pelvic cavity, and make the fetus grow more advantageously. As pregnancy draws to a close, relaxin further relaxes the ligaments around the pubic symphysis and sacroiliac joints, preventing the birth canal from becoming bony and narrow, and at the same time softens the cervix and vagina to facilitate the delivery of the fetus. This not only affects the strength support of the expectant mother's spine and pelvis, but also affects the supporting strength of tissues such as bones, muscles, and ligaments.

Adjust your posture and relax your back muscles

Since lower back pain during pregnancy is related to fatigue of the lower back muscles caused by the increased weight-bearing on the waist and abdomen, expectant mothers can adjust their posture appropriately and relax the lower back muscles to relieve pain whether they are standing, sitting or sleeping.

Standing posture: Keep your chest and head up, lean your abdomen slightly forward, pull your hips slightly forward, and bend your legs slightly. This posture allows the muscles in the lower back to relax, relieving lower back pain.

Sleeping position: It is recommended to sleep on your side. Expectant mothers with lower back pain can buy a pregnancy pillow to help them bear the force of their abdomen. When lying on your side, you can also bend one leg and place your knee on the pregnancy pillow.

Sitting Posture: Keep your back and shoulders straight while sitting. Sit with your buttocks against the back of the chair, leaning as close to the backrest as possible, or sitting on the entire chair if there is no backrest. Distribute your weight evenly across your hips, uncross your legs, and keep your feet flat on the ground. Avoid sitting in the same position for more than 30 minutes. When working, pay attention to adjusting the height of the chair and table. You can lean your elbows on the chair handles and try to keep your shoulders relaxed. Especially mothers who sit in the office for a long time should pay more attention to their sitting posture.
