Lower Back Pain During Pregnancy: Causes, Relief Tips, and When to See a Doctor
20 Feb 2025
Why Does Lower Back Pain Happen During Pregnancy?
Lower back pain is one of the most common pregnancy complaints, affecting up to 75% of moms-to-be. As your body changes to accommodate your growing baby, extra weight, posture shifts, and hormone fluctuations can lead to back discomfort. The good news? While lower back pain can be frustrating, there are safe and effective ways to relieve it—so you can stay comfortable throughout your pregnancy.What Causes Lower Back Pain in Pregnancy?
Several factors contribute to back pain while expecting, including:1. Weight Gain
- During pregnancy, you gain extra weight, which puts more pressure on your lower back and spine.
2. Posture Changes
- As your belly grows, your center of gravity shifts forward, making you lean back to balance. This strains your lower back muscles.
3. Hormonal Changes (Relaxin Hormone)
- Pregnancy releases the hormone relaxin, which loosens ligaments and joints in preparation for labor. This can make your lower back less stable and more prone to pain.
4. Muscle Separation (Diastasis Recti)
- Your abdominal muscles stretch to make room for your baby, sometimes separating in the middle. This weakens your core, putting more strain on your back.
5. Stress and Tension
- Emotional stress can cause muscle tightness, especially in the lower back and shoulders.
