What causes low back pain during pregnancy

Changes in hormones in the body during pregnancy can make pregnant women feel uncomfortable, and their enlarged belly makes it inconvenient to move, which can easily lead to back pain in pregnant women. Pregnant women should pay attention to a balanced diet, avoid eating spicy foods, eat more calcium-rich foods, and if they have lower back pain, they should rest in bed more. Eating some fruits is also good for the fetus. The baby's skin will be smoother after eating fruits.

1. Hormonal changes in the body during pregnancy.

Hormonal changes in the body after pregnancy can cause many pregnancy reactions in pregnant women, and back pain is one of them. After pregnancy, hormone changes in the body cause the pelvic ligaments to relax to adapt to the growth of the fetus and the needs of future delivery. This will also cause the ligaments and fascia in the waist to relax, reducing their elasticity, making them prone to strain and causing low back pain.

2. The placenta and amniotic fluid increase, and the lumbar spine is overloaded.

This is the main reason for back pain in pregnant women. After pregnancy, the fetus and its attached placenta, amniotic fluid, etc. grow larger and larger day by day, increasing the burden on the front of the lumbar spine. In order to maintain balance, pregnant women must contract their back muscles forcefully when standing, causing the pelvis to tilt forward, forming a unique straight back posture. The back muscles continue to contract and they cannot relax and rest. Over time, fatigue will cause back pain.

3. Reduced amount of exercise.

After pregnancy, the amount of exercise for pregnant women is greatly reduced. Some pregnant women even lie down or sit for a long time. Lack of exercise can also cause a decrease in basic physical strength, thereby causing back pain in pregnant women.

4. Insufficient calcium supplementation.

During pregnancy, the fetus needs a lot of nutrients such as calcium to develop. If these nutrients are not consumed enough, it can easily cause osteoporosis and decalcification in pregnant women, which can also cause back pain.

The causes of low back pain in pregnant women vary in the early, middle and late stages of pregnancy. The back pain in pregnant women in the early stages of pregnancy will not be very severe. It is mostly back pain, which is mainly caused by the retroverted uterus and compression of the rectum and ligaments. Pregnant mothers do not need to worry.

Low back pain in the middle and late stages of pregnancy is mostly caused by the rapid development of the fetus, which causes the uterus to gradually enlarge and the abdomen to move forward. In order to maintain balance, the upper body tends to lean back, causing excessive lordosis of the spine and continuous tension in the back extensor muscles, resulting in excessive fatigue of the waist and back, which can easily lead to low back pain.
