Back pains are often common during pregnancy. Here’s why.


Motherhood speaks to Dr Pamela Tan, consultant obstetrician and gynaecologist, TLC Gynaecology Practice, Thomson Medical Centre, about back pains during pregnancy and its remedies.

Dr Tan outlines the three main causes of back pains during pregnancy:


Strain on the Back Muscles

As the pregnancy progresses, the uterus becomes heavier and pregnant women naturally bend forward. To keep their balance, their posture changes and they start leaning backward, which makes the back muscles work harder. This extra strain can lead to pain, soreness, and stiffness.


Weakened Abdominal Muscles

The abdominal muscles, which support the spine and play an important role in the health of the back, stretch and may weaken during pregnancy.


Pregnancy Hormones

Towards the third trimester, relaxin is produced to prepare for the passage of the baby through the birth canal. This hormone relaxes the ligaments in the joints of the pelvis and allows the joints to become more flexible. However, it can also cause back pain if the joints become too mobile.
