What is Back Pain in Pregnancy?
Back pain is very common during pregnancy, affecting most people at some point. It happens as hormones loosen the ligaments supporting the spine and pelvis in preparation for birth, while growing weight and a shifting centre of gravity put extra strain on the lower back.
It usually develops in the lower back but can also affect the upper back, especially as the bump grows and posture changes. While uncomfortable, it's rarely a sign of a problem with the pregnancy itself.
02 · Understand
Clinical context
Posture and support make a real difference
Small adjustments — like sitting with better back support, avoiding heavy lifting, and wearing flat, supportive shoes — can meaningfully reduce strain on the lower back throughout pregnancy.

04 · Prevent & manage
Practical steps
Avoid Heavy Lifting and Prolonged Standing
Both can put extra strain on an already loosened lower back and pelvis during pregnancy.
- 1Practice good posture.Stand tall, avoid slouching, and use a supportive chair with good lower back support when sitting.
- 2Wear flat, supportive shoes.Avoid high heels, which shift your centre of gravity further and increase strain on the back.
- 3Sleep on your side with support.A pillow between the knees and under the bump can ease pressure on the lower back and hips.
- 4Stay gently active.Pregnancy-safe exercises like swimming, walking, and prenatal yoga can strengthen supporting muscles.
- 5Apply heat.A warm (not hot) compress on the lower back can help ease muscle tension.
