What causes back pain in pregnant women?

　　What causes back pain in pregnant women? ? Pregnant women will experience back pain from the first trimester to the third trimester. What causes this?

　　1. Mild separation of pubic symphysis

　　Changes in hormones in the body, especially the influence of progesterone, cause the pelvic joint ligaments to relax. After relaxation, the pubic symphysis will be slightly separated, and the separation will cause joint pain. The pain caused by this separation of the pubic symphysis is bearable to most people. If the pubic bone is greatly dislocated, resulting in ligament strain, edema, and difficulty walking, bed rest is necessary.

　　2. Subject to increasing pressure month by month Uterus oppression

　　As the pregnancy progresses, the uterus increases. Because the uterus grows forward, it forces the pregnant mother to stand up straight, with her head and shoulders back, her abdomen protruding forward, and her waist also protruding forward. Over time, it will cause back pain.

　　3. It may also be caused by chronic pyelonephritis

　　Ureteral injury during pregnancy nerve Due to the influence of body abnormality changes, the ureter becomes thicker, the accumulated tension is reduced, peristalsis is weakened, and the speed of urine flow is slowed down, which may cause infection. In the second trimester, it will cause the renal pelvis and ureter to expand, which can easily compress the right ureter and the right nerve (because the uterus rotates to the right, so pregnant women lie on the left side for the same reason), causing chronic pyelonephritis and lower back pain. 》》》 Pregnant woman appears7Be careful with these symptoms
