Causes of back pain in pregnancy

Back pain is caused by changes happening to your body to accommodate your growing baby.

These changes include:

  • your posture changing to accommodate the increased weight you're carrying
  • changing hormones - these can make your pelvis and back feel weaker
  • more pressure and less support for some joints in your back and pelvis
  • tiredness and stress - these can intensify any pain or discomfort in your body

How to reduce back pain in pregnancy

Being aware of your posture and trying to improve it can reduce your risk of back pain.


  • think about your posture when you are sitting or moving

  • avoid standing for long periods of time

  • tuck your hands under your bump for support if you have to stand for long periods

  • keep the weight even between your two legs - avoid shifting your weight to the left and the right leg

  • wear comfortable, supportive, low-heeled shoes

  • sit with your bottom against the back of a chair and sit up tall - put a small cushion at your lower back if needed

  • get all the sleep you can - this can help reduce pain

  • stay active with gentle exercises and stretching


  • do not lift heavy objects - if you need to lift anything, bend your knees and keep a straight back

Correct posture during pregnancy

Correct posture in pregnancy can help to improve back pain

Change your position often to avoid over-stressing your joints.

You can also practice improving your posture by following these steps:

  1. Keep your knees soft.
  2. Stack your pelvis under your rib cage.
  3. Tilt your pubic bone and breastbone towards each other.
  4. Roll your shoulders back and down.
  5. Tuck your chin.
  6. Keep the back of your neck long.

Do a back exercise

You can try the following exercises.

Child's pose

This exercise helps to relieve the pressure on your back. It give the joints and muscles of the lower back space to open and lengthen.

  1. Kneel on the floor, with your knees spread wide and your feet in close to each other. This allows space for your baby bump.
  2. Now allow your bum to sit right back onto your heels. Place a cushion at your heels if it feels more comfortable.
  3. This should feel like a relaxing, comfortable stretch in your low back.


This exercise will help strengthen the abdominal (stomach) muscles that can support and ease back pain during pregnancy.

  1. On all fours, make sure your knees are under your hips and your hands are under your shoulders. Your spine should be straight and in a neutral 'box' position.


2. Hollow your back as shown in the image above.

3. Then follow this with a rounded spine, as shown in the image below.

5. Breathe comfortably and hold this position for 20 seconds.

6. Return your back to the neutral position in step 1.

7. Repeat this 5 times.
